OVERVIEW

NETWORK CONFIGURATION

This section describes the network communications protocol and the individual modules used in
the PowerCommand network. This section also describes network media, network power supply, and
physical connection requirements. For a definition
of the terms used in a PowerCommand network, refer to the Glossary in Appendix A.

The PowerCommand network uses a multidrop bus
topology (Figure 2-2). The network is made up of individual modules that are connected by twisted-pair
communications cable for the transmission of network data. Network power is transmitted over a second pair of wires.
Figure 2-1 shows a typical network with several
modules. Refer to Figures E-1 thru E-3 in Appendix

outputs for each device as network variables.

SYSTEM DESCRIPTION
The PowerCommand Network is a distributed control network. Echelon LonWorks technology provides the communications protocol via Echelon’s
Neuron Chip and firmware. The network consists
of nodes (for example: PCCs with Genset Communications Modules, Digital I/O Modules, Controls
Communication Modules, and Network Gateway
Modules) wired together on a common network
data bus.

Nodes that do not have a local source of uninterrupted power are supplied by the network power
lines.

Neuron Chip
Each node contains a Neuron Chip. The primary
function of the Neuron Chip is to serve as a communications link between the system component located at that node and other system components on
the network. The Neuron Chip also provides the
node with some local processing power to read
switch positions, drive outputs, read analog data,
etc. The Neuron Chip communicates by directly
transmitting and receiving through a transformercoupled transceiver.

The control of the system does not reside in a central device, but rather is distributed at the system
component level. That is, each node has its own intelligenceintelligence needed at that location to
perform functions for that particular component.
The nodes communicate control and monitoring information to one another over the network data bus.

SYSTEM MODULES

The nodes, their connections to one another, and
the modules/devices they control/monitor collectively form the distributed control system. A distributed control system is a more robust control
scheme than a conventional central control system.
Single points of failure in the distributed control system do not necessarily render the whole system inoperative.

PowerCommand Control
The PowerCommand Control is a microprocessorbased control for Onan generator sets. It provides
fuel control and engine speed governing, main alternator voltage output regulation, and complete
generator set control and monitoring.
The operating software provides control of the generator set and its performance characteristics, and
displays operating information on a digital and analog display panel.

Communications Protocol
A distributed control network operates on a peer-topeer communication protocol, whereby any device
on the communication channel can communicate
with any other device at any time.

The PowerCommand Control (PCC) communicates through the GenSet Communications Module
with other modules, such as a Network Annunciator
Module or Network Gateway Module.
The PowerCommand Control is covered in your
generator set Installation, Operator’s, and Service
manuals.

Messages can be prioritized so that critical control
messages have first access to the network. Reliability of transmission is provided through use of acknowledged or repeated message service levels.
Accuracy of the message is checked by cyclical redundancy checking.

GenSet Communications Module (GCM)

Network Gateway Module

The GenSet Communications (GCM) is mounted
inside the PCC, and is required for connection of the
PCC to the network.
The GCM provides an interface for data between
the PowerCommand Control and other modules on
the network. It communicates with the PCC through
the PCC’s serial port, as well as by monitoring various PCC inputs to determine the operating state of
the control. For example, the GCM monitors PCC
data such as voltage, current, engine speed, and oil
temp; and then stores it for the network.
The GCM also provides some direct local control
and monitoring of the PCC. Outputs from the GCM
allow it to “wake up” the PCC when needed, or to
cause an emergency shutdown on command. It
monitors Not-In-Auto mode and battery voltage
(when the PCC is asleep).
The GCM is installed piggyback on the analog
board within the PCC. Description of the GCM is
covered in Section 5.

The Network Gateway Module (NGM) provides a
network interface to a PC either directly or through a
modem. It translates network protocol into a protocol that can be understood by a PC.
The NGM connects to network data wire through an
RJ45 jack. Connecting to the network requires a 24
AWG communications cable (cables are included
with NGM kit) . The NGM receives its power from
AC wall power, and should be backed up by a standby uninterruptable power supply (UPS).
The NGM allows software running on a PC to access, and control all modules on a network. The
PowerCommand Software uses this module to access the network.


An NGM that is used for monitor
and control of a site cannot be used to install a
site. Failure to use a separate installation NGM
will cause the NV data stored in the site monitoring NGM to be destroyed. If this occurs, do a Repair/Replace in LonMaker on the Site NGM.

Digital I/O Module

LonMaker and PowerCommand Configuration
Tool software require a unique network gateway
module referred to as the “Network Installation
Gateway” for installing and servicing a network
(shown in Figure 2-1).

The Digital I/O Module (DIM) provides a group of
relay contact outputs and discrete inputs for interfacing the PowerCommand System to alarm or status outputs and to equipment that does not have
compatible communications capability.
The Digital I/O Module provides sixteen 5A,
250VAC/30 VDC Form-C dry contact relay outputs,
which are driven by data from the network. The contacts are connected to pluggable terminal blocks for
field wiring. Each relay can be programmed to operate from any Boolean variable on the network. The
module also includes four digital inputs to couple
user inputs to the network for use elsewhere in control or monitoring.
Description and installation of the Digital I/O Module
is covered in Section 6.

Description of the NGM is covered in Section 7.

Controls Communications Module
for Generator Set and Transfer Switch
Monitoring

Junction Box/Terminator
A Junction Box/Terminator (JBT) provides connection points for network power and data wire. Junction Boxes may be used throughout a network for
connecting in Pass Thru, Local Loop and Stub configurations. The JBT is a potted assembly.

The Controls Communications Module (CCM) allows interfacing the network to conventional nonPCC generator sets, transfer switches, system or
breakers.
These modules monitor discrete inputs, AC and DC
analog inputs, and communicate data to the PowerCommand Network.
The CCM has 32 discrete inputs and 7 analog inputs.
The module also includes two Form-C output relays
and two Form-A output relays to provide control of
the monitored equipment from the network. For example, these outputs can be used to initiate a test
within a transfer switch, or to remotely start a generator set.
Description of the CCM for genset applications is
covered in Section 10, and the transfer switch applications are covered in Section 11.

The JBT is required when connecting an NGM to
the network.
A junction box provides two 6-position pluggable
connector for data and power, two RJ45 jacks for
24AWG stub connections (e.g. NGM), a switch to
connect the data lines to a terminator circuit, and a
switch to select either a Pass Thru or a Local Loop
connection between the data lines on the two connectors.
Description of the JBT is covered in Section 8.

Network Annunciator Module
The Network Annunciator Module (NAM) combines
a hardwired PowerCommand System Annunciator
with a Digital I/O Module. The NAM is connected to
the network by twisted pair communication wire.

Network Router
The Network Router (RTR) connects two communications channels by passing messages between
the two channels. The PowerCommand Network
Router is configured to connect two twisted pair/
transformer isolated 78kb (TP/XF-78) channels.

The NAM has 20 LEDs to annunciate alarms. In
NFPA 110 applications the network directly controls
16 of the LEDs and indirectly controls one LED
(DS3). The remaining three LEDs can be hardwired. In non-NFPA 110 applications the network
controls 16 of the LEDs and four can be hardwired.
This module has its own Operator’s manual
(900-0282).

The Router can be used within a PowerCommand
Network to extend the physical length of the network beyond 4600 feet (1402 m) and/or increase
the maximum number of nodes to more than 44
nodes. Refer to the Section 12 for application information on the Network Router.

The NAM is covered in Section 9 of this manual.

Redistribution or publication of this document,

This topology requires that there be only two ends
to the network. Stubs off the network bus can be no
longer than 10 feet (3 m). The maximum bus length
of a single channel is 4600 feet (1402 m).

DATA TRANSMISSION MEDIA
The modules communicate at 78 kbps over a bus of
22 AWG UL Level IV (or EIA Category 4) twisted
pair communications wire. The network data signal
is coupled to the twisted pair wire by transformercoupled transceivers in each node. Nodes are isolated by transformer from the data lines, which
makes the data wiring polarity insensitive. A high
degree of noise immunity is achieved with this medium.

A Local Loop must be used when branching off for
more than 10 feet (3 m). The Local Loop lets you
wire “out and back” to a module. Add the length of
the local loop in both directions to the overall bus
length.
Both ends of the network data bus must be terminated with a terminator circuit. Proper termination of
the network is important for reliable communications. All Onan nodes have the terminator circuit
built in except the NGM and Router. Termination is
activated by a slide switch.

Wiring and connection of data transmission media
is covered in the individual module sections.

NETWORK TOPOLOGY
The wiring topology is a multidrop bus topology.

Tension: All cabling should be free from tension at
both ends, as well as over the length of each run.

WIRING GUIDELINES
Communication over unshielded twisted pair (UTP)
could be distorted by external sources of electromagnetic interference (EMI), especially if the conductors are physically degraded in any way. To
avoid or minimize this interference, observe the following guidelines.*

Twisted pairs: All terminations should be made in
such a way as to minimize the extent to which
each twisted pair is unraveled at the point of its
physical termination. Allow no more than 0.5 inch
(13 mm) of exposed untwisted pairs.
UTP cable bends: UTP cable bends, or radii,
should be no less than eight times the cable diameter.



Electromagnetic interference (EMI)
can cause communication signal distortion,
which can cause network failure and unintended equipment operation. Read and follow
these wiring guidelines.

Harsh, hazardous, or corrosive environments:
Communications wiring should not be installed
where vapors, fumes, corrosives, dusts, or other industrial byproducts are present without taking appropriate precautions to protect the cables. Installers and cabling manufacturers of the materials involved must be consulted in all such cases.

Observe all local wiring codes. Refer to the NEC
(NFPA70) section on Wiring Methods and Materials
for general wiring methods and procedures.
Routing: Whenever possible, cabling should be
installed over corridor areas or along lines that are
parallel to the contours of buildings. All deviations
from straight runs should be made at right angles.
Keep wire away from sharp, abrasive, and hot surfaces.

Grounding and bonding: Although the use of UTP
does not involve the use of shielded cables in horizontal station runs, the use of shielding in high-paircount UTP riser cables as well as cables of all types
used in outdoor conditions is not uncommon. In
some cases, qualified installers or manufacturers
will make related recommendations in the interest
of human safety or mechanical protection of
installed cables (e.g., shielding against rodents).

Separation from sources of EMI: All cabling
should be installed in such a way as to comply with
the minimum separations from AC power sources,
as listed in Table 2-4.

When shielded cables are used, all applicable regulations for grounding and bonding as defined by local building codes for electrical materials must be
strictly adhered to.

In general, communications wiring should not be located in spaces that are shared with electrical panels, transformers, or other high voltage equipment.

24V GenSet Battery Power Supply

NETWORK POWER
This section describes the methods of supplying
power (referred to as network power) to those network modules that require an external power
source. Observe all local wiring codes and regulations when designing and installing network power
wiring.

The genset batteries cannot deliver network power
over a long distance due to the voltage drop during
cranking. The genset batteries require a battery
charger that can supply the network load and maintain the batteries.

The modules that require DC network power are:
• Digital I/O Module (DIM)
• Network Annunciator Module (NAM)
• Controls Communications Module – GenSet
Applications (CCM–GenSet)
• Controls Communications Module – Automatic
Transfer Switch Applications (CCM–ATS)
The DIM, NAM and CCM-Genset modules can be
powered by a 24V genset battery. The 24V genset
battery can supply one or more of these modules
within specific distance limitations.

Refer to the genset wiring diagram for fused B+ connection points. (On PCC gensets: Use the TB1 terminal in the customer connection box. TB1–12 [+]
and TB1–13 [–] is fused at 10 amps, and are the preferred connection points. If voltage is not available
at these points, use TB1–1 [+] and TB3/4 [–], fused
at 20 amps. Make sure that the total circuit load
[load factor] does not exceed the fuse rating.)

SELECTING NETWORK POWER
CONFIGURATION AND WIRE SIZE

The CCM–Genset module can also be powered by
a 12V genset battery power supply. The distance is
very limited and no other types of modules can be
powered off the same network power circuit. Refer
to Table 2-6 for distance and wire gauge requirements. (When powering CCM modules only from a
24V genset battery, refer to Table 2-7.)

The following section describes the procedures for
selecting the copper wire gauge needed to supply
network power. The wire gauge selected will be a
function of the type and number of modules used,
the type of power supply selected, and the distance
between the power source and the farthest module
in the power supply circuit. Do not use twisted pair
data wire for DC power.

The CCM–ATS network power will be supplied by a
12VDC battery that is included along with a battery
charger in the CCM–ATS kit.
A 12V genset battery will not provide an adequate
power supply for DIM’s and NAM’s. In cases where
the genset is powered by a 12V battery, a separate
power supply must be used.

Use this procedure for developing network power
circuits for DIM, NAM and CCM-Genset modules
only. (CCM-ATS modules are not included because
they are equipped with their own power supply.)

Locate the CCM as close to the device being monitored as possible. Do not mount the CCM on a genset or vibration damage can result.
If current transformers will be monitored, the distance limitations between the current transformers
and the CCM will generally be more restrictive than
the network power distance limitations. Refer to the
appropriate CCM section for current transformer
distance charts.

Refer to Figure 2-6 for illustrations of typical circuit
configurations and notes.
1. Determine the number and type of load modules (DIM, NAM and CCM-Genset modules).

2. Calculate the Total Load Factor by adding up
the individual load factors for each DIM, NAM,
and CCM-Genset in each circuit.

Each CCM-GenSet has a load factor of: 2.40
Each DIM has a load factor of: 0.10
Each NAM has a load factor of: 1.20
3. Determine the distance between the power
source and the farthest load device (DIM, NAM
or CCM-GenSet module) in the circuit.

# + / '

4. Look up the required minimum copper wire
gauge. Refer to Table 2-5 for 24V genset battery power supply.

Example:
Application: The network plans call for one CCMGenset at 40 feet (12 m), one DIM at 50 feet (15.2
m) and one NAM at 300 feet (91.4 m). The farthest
module from the network power source is the NAM.
The top drawing in Figure 2-6 shows each of these
modules being supplied in one circuit.

/5! " (
( () ( 

/ 4
#+ '

Calculation: The total load factor =
(1 X 2.40) + (1 X 0.10) + (1 X 1.20) = 3.70

 4
# + / '

Wire Size Required: Look up the total load factor
(3.70) in the first column of Table 2-5. Then look
across the table to find a distance equal to or greater
than the distance to the farthest load device (300
feet). Table 2-5 indicates that the maximum distance obtainable is only 201 feet, this power supply
is not adequate to supply all of these modules in one
circuit.

( /5! " (
 () (   *

The circuit can be redesigned so the CCM-GenSet
module is supplied by a second circuit off the same
source (center diagram in Figure 2-6). Be careful
not to exceed the current rating of the circuit. (The
load factor equals the maximum current draw.)

–OR–

The circuit can be supplied by more than one genset power supply if available (bottom diagram in
Figure 2-6). Do not connect separate network power sources in parallel or damage to the batteries will
result from overcharging.

 4
# + / '

Using either of the redesigned circuits, recalculate
the wire gauge based on steps 1 thru 4. The CCM–
GenSet with a load factor of 2.40 can be supplied
using 18 gauge wire. The DIM and NAM with a total
load factor of 1.30 can be supplied using 14 gauge
wire.

ABOUT THIS SECTION
This section describes procedures for the logical
installation and connection of the various modules
on the network using LonMaker. Refer to the Glossary section for definitions of network terms.

The following section (Section 4) describes the
installation and use of PowerCommand Configuration Tool (PCT). PCT is used to complete the network installation.

Much of the material in this section is derived from
the Echelon LonMaker Installation Tool Users
Guide. The Echelon manual is included with the
LonMaker software, and should be considered a
reference companion to this manual.

The step-by-step procedural information in this section is intended for use in conjunction with operating
LonMaker software. Read all introductory and overview material, and skim over the major headings of
the procedures ahead of time; but do not expect the
procedural text to be very useful until you are operating the software and can view its menus and features.

Use this manual for basic, Onan-specific network
installation, operation and service information
(hardware and software).

POWERCOMMAND NETWORK OVERVIEW
Devices, or modules on a PowerCommand Network communicate with one another by sending
measurements, instructions, signals, and other
messages. The devices sense monitored conditions and network input messages, and respond
with appropriate actions and output messages.
In a PowerCommand Network, modules are connected to a physical transmission media. In the
PowerCommand Network, however, physical attachment (wiring) is not enough to “install” the system. The physical connections only provide a path
for sending and receiving control messages.

Items 1 through 3 cover introductory and background information.

PowerCommand Software for Windows (refer to
PowerCommand Configuration Tool in this section).

With a PowerCommand Network, you must also
install and connect devices by using the LonMaker
software, a personal computer, and a Network
Installation Gateway to send messages over the
network to each device. This procedure, the logical
installation and connection of devices using LonMaker software, identifies all devices on the network and assigns, or links, outputs from specified
devices to inputs on other specified devices (binding). Many of these terms are defined in the Glossary in Appendix A.

The network installer will need documentation listing the device-specific network variable input and
output connection pairs. These network variable
connection instructions define logical input/output
connected pairs, just as a point-to-point wiring diagram defines physical input/output connected
pairs. Refer to the Forms in Appendix C.
Device-specific network installation procedures are
covered in the individual module sections.

Network Installation Gateway Module.

NETWORK INSTALLATION SCENARIOS
There are two basic installation scenarios that you
can use when installing a new network:

The installer then runs the LonMaker installation
software to perform several functions including defining components of the network and identify specific device nodes by pressing their individual service pins when prompted to do so. Next the installer
runs the PCT software to further define and download module configuration information and to make
a CSV file for use by PowerCommand Software for
Windows.

• Setup before going to the site, then install and
test at the site.
• Setup, install and test at the site

Setup Before Going To The Site
With this scenario, everything about a new network
configuration is predefined using LonMaker and
PCT before you go to the site. Defining network
components like domain, channel, location, devices, and defining connections can be done before
going to the actual installation site. This information
is stored in the site directory for use at the site.

As a final checkout, the installer should run PowerCommand Software for Windows to thoroughly test
the installation connections, alarms, etc. Refer to
the PCW manual for PCW operating instructions.
This must be done with an NGM configured for
PCW (not the Network Installation Gateway).

At the installation site, the network installer uses
LonMaker to “install” each physical device and PCT
to install configuration information and to make a
CSV file for use by PowerCommand Software for
Windows (PCW). Any changes must be made at the
site.

Any future modification of an existing network
installation must be done on-site.

SETTING UP NETWORK
INSTALLATION TOOLS

Setup At The Site

Refer to the the Required Installation Tools in Section 1 for the minimum PC system requirements.
LonMaker software, a network gateway driver, Network Module Library and PCT must be installed on
your computer before you can begin the network
installation procedures.

With this scenario, the network installer connects to
the site network and uses LonMaker to define network components such as domain, channel, location, devices and define and make connections between device inputs and outputs. The installer will
also use PCT to define module configuration information and to make a CSV file for use by PCW at the
network site.

Normally the LonMaker software, Network Module
Library, the network gateway driver and PCT are
installed before you arrive at the installation site.
These programs only need to be added to the installation computer once.

Procedure Overview
Initial network setup, including assigning connections (binding), can be done off-site, prior to the
physical installation or at the site. This creates a site
database.

To connect the installation PC that runs LonMaker
software to a PowerCommand network, you must
connect a Network Installation Gateway between
the network and the PC. This gateway can be connected to the network at a Junction Box/Terminator,
a GCM or at a CCM.

After the devices are physically connected at the
site, the installer must connect a PC (with LonMaker

2. At the DOS prompt type:
A:\BIN\DINSTALL ↵ Enter\Return.

Network Module Library Installation
The Network Module Library (NML) contains the
data files that are used to create or update a PowerCommand Network. The NML software is used in
conjunction with LonMaker software to install a
PowerCommand Network. The NML software is updated as additional features and modules become
available.

LonMaker Software Installation
This software is provided on two floppy disks. The
files on these disks are compressed, so you must
use the INSTALL program on the LonMaker disks to
transfer the files to your computer.
The INSTALL program will modify the the PATH
statement in the AUTOEXEC.BAT file so that when
the computer is rebooted, the LonMaker directory is
in the defined path.

Install the latest NML software as follows:
1. Insert the Module Library Disk into the floppy
drive (A:).
2. At the DOS prompt type:
A:\INSTALL [drive] ↵ Enter\Return.

Insert disk 1 and type: A:\INSTALL (press ↵ Enter\Return).

Note: [drive] Optional. If the drive is not specified, the
drive defaults to C:. To install to a drive other than C:,
enter the drive letter and colon.

Follow the prompts and choose a drive when requested. When prompted for a subdirectory, editing
the path to add the ONAN directory (\ONAN\LNM)
will help organize the network installation files. Select the graphical version. Answer yes “Y” to modify
the config.sys file.

The install routine creates a directory called
\ONAN. The Module Library is installed in the
\ONAN directory in a subdirectory called NML (e.g.
C:\ONAN\NML).

The software installation places LonMaker files in a
new directory named LNM. Reboot the computer to
activate these changes.

The install routine also creates a subdirectory
named BIN (C:\ONAN\BIN). BIN contains the driver
for the Network Installation Gateway.
The install program deletes previous versions of the
Module Library and updates the Installation Gateway driver. Review the README.TXT file for the latest information on the NML software.

Create Or Update A Network
Each PowerCommand Network installation site
must have its own site directory. This directory
will contain the files necessary to run LonMaker.
There can be many site directories on your computer with each one corresponding to a different network installation. LonMaker software resides in its
own directory (C:\ONAN\LNM), separate from any
of the site directories.

A line must be added to the config.sys file using a
text editor. Example using MS DOS:
From the C:\ prompt, type edit config.sys to edit the
config.sys file.
Add the following line:
devicehigh=c:\onan\bin\ldvslta.sys /p1 /b9600 /m

A utility program is included to create a new site directory or update a current site with new NML data
files. The NML install routine created a subdirectory
named SITES (C:\ONAN\SITES) to contain network sites. To create or update a site:

Note: Be sure to include a space between ldvslta.sys
and /p1, between /p1 and /b9600, and between /b9600
and /m.

The /p1 specifies that the Network Installation Gateway is connected to COM1 on the computer. Use
/p2 if connected to COM2.

1. Change directories (CD) to ONAN
2. From the C:\ONAN> directory enter the following:
pcnet c:\onan\sites\

The /b9600 specifies the Network Installation Gateway baud rate (do not change). The /m specifies the
protocol (do not change).

Example where the site_id is site_10:
pcnet c:\onan\sites\site_10 ↵ Enter\Return

Network Module Library Removal
To remove the Network Module Library:

This utility creates a site directory (\site_10) located
in the \onan\sites directory or updates the existing
site.

Procedure to Define a Domain

LONMAKER NETWORK SETUP
The first steps for installing a network require that
you describe the specific components of the network to the LonMaker program. With this network
setup procedure, you define domains, channels,
locations, and devices. If you encounter error messages, refer to the LonMaker Installation Tool
User’s Guide, section on Error Messages and Troubleshooting.

You must define a domain for the devices you are
going to install. Follow these steps:
1. Click on the Domain Setup task button. The list
of defined domains appears on the DOMAIN
SETUP screen (Figure 3-5).
2. Click on the Define action button. The DEFINE
DOMAIN screen appears.

The network designer supplies most of this information, along with a plan for the physical installation of
devices and communications media. Forms for network design are provided in Appendix C.
As you define components (domains, locations,
channels, and devices) LonMaker records them in a
network database—in the project subdirectories
DB_INST. These definitions affect the operation of
the network only after you install the components.
Installing and connecting devices is covered later in
this section.

3. Type in “domain_∅∅” for the new domain
name (in special cases, use a new name of up
to 16 characters, including spaces). Use the
default ID of “∅∅” in the domain ID, if provided.
Do not change the Domain Auth. Key, (all
F’s) unless instructed specifically, to do so.
4. Click on the Done action button if this is the only
domain you want to define at this time. Click on
the Save action button if you want to define
another domain.

Defining and Selecting a Domain
You must name at least one domain for the devices
on your network.

Procedure to Select a Domain

A domain is the top level of organization of the network. Normally, all of the devices in a domain are
assigned only to that one domain.

If your network installation contains more than one
domain, before you work with application devices,
you must select the domain that they belong to.

• A network must have at least one domain.
• A domain has a unique name.
• A domain has a unique ID number. Normally,
this ID limits communication to devices in the
same domain.
• An application device can belong to one or two
domains.

1. Click on the Domain Setup task button. The list
of defined domains appears on the DOMAIN
SETUP screen (Figure 3-5).
2. Click on the domain you want to select. The
name of the selected domain appears at the
top of the screen.

Most PowerCommand network installations will
have only one domain.

Procedure to Define a Channel

Defining and Selecting a Channel

You must define a channel for the devices you are
going to install. Follow these steps:

You must name at least one channel for your network.

1. Click on the Channel Setup task button. The list
of defined channels are displayed.
2. Click on the Define action button. The DEFINE
CHANNEL screen appears.
3. Channel Name: Type in the channel name
“tp78_channel1”.

Channels are the physical communications media
that connects the devices and the properties of
these media (such as transmission speed). Most
PowerCommand network installations will have
only one channel (twisted-pair wiring and 78 k bits/
second transmission speed).

4. Channel Type: Click on the  symbol to the
right of the Channel Type text area to see a list
of available channel types. Double click on
channel type “tp/xf–78” to choose it.
5. Click on the Done action button if done defining
channels, otherwise select save.

An additional channel will be required if the distance
between devices exceeds the operating range of
the communications medium or if the number of devices exceeds the capacity of the channel. Although LonMaker can install up to 127 devices on a
channel, the communications media (22 AWG
twisted pair) has a lower limit (44). Refer to the material on data transmission media and network data
specifications in Section 2.

Procedure to Select a Channel
1. Click on the Channel Setup task button.
2. Click on channel name. From here, you can remove an unused channel, display name and
type information about a channel, or attach the
Network Installation Gateway. You can initiate
these actions by clicking on the Remove, Info,
or Attach action buttons, respectively.
3. Select the channel that the Network Installation
Gateway is connected to. Select Attach.

If the network contains a Router, two channels must
be defined (Refer to the Router Section). One additional channel must be defined for each additional
router.

Defining and Selecting a Location

Procedure to Define a Location

You must name at least one location for the devices
on your network.

You must define a location for the devices you are
going to install. Follow these steps:
1. Click on the Location Setup task button. The list
of defined locations appears on the LOCATION
SETUP screen (Figure 3-7).
2. Click on the Define action button. The DEFINE
LOCATION screen appears.
3. Type in the new location name (up to 16-characters, including spaces).
4. Click on the Done action button if this is the only
location you want to define at this time. Click on
the Save action button if you want to define
another location.

A location is a subdivision of a network that contains
one or more related devices. Locations are available for the convenience of the designer and installer. They allow you to organize a network installation.
Locations can be defined to correspond to physical
sites in the project. How locations are defined for a
particular installation project is up to the discretion
of the designer and the installer.
• A network must have at least one location.
• All modules must be assigned a location.
• A module can belong to only one location.

Procedure to Select a Location
Before you work with application devices, you must
select the location that they belong to.
On any screen that shows the Locations list, click on
the location name. A ♦ symbol appears to the left of
the selected locations name.
The “ALL” locations name will show all devices in all
locations.

These connections are software (logical) connections, not physical connections between devices.

INSTALLATION OF DEVICES
WITH LONMAKER

LonMaker software is used to connect selected
pairs of application devices. The first step in connecting devices is to select a “hub” device. The hub
device is the first device that you will use to connect
to several other devices. For example, to connect
the device named “GCM_1” to the devices named
“DIM_1” and “DIM_2,” you should select “GCM_1”
as the hub device. You then select devices to connect to the hub. Refer to Appendix C for Application
Table Consumption to review the number of connections that can be made. In general the DIM and
NAM can connect to a maximum of 5 devices and
the CCM and GCM can connect to up to 15 modules.

Network installation actually involves two distinct
processes:
• Connecting Modules is the process of assigning (or “binding”) device-to-device connections—linking an output variable of one device
to an an input variable of another device. This
procedure is described under: CONNECT
PROCEDURE.
Initial network setup, including assigning connections (binding), can be done off-site, prior to
the physical installation.
(Any modification of an existing network installation must be done on-site.)

You can connect a device to itself by connecting
(binding) its inputs to its outputs.

• Installing Modules is the process of identifying each device as a unique member of the network. This procedure is described under:
INSTALL PROCEDURE.

Connections occur in two steps:
• Pending: When you first specify connections,
they are stored as proposed or pending connections. LonMaker places a+ symbol next to
device names involved in pending connections.
• Completed: When you click on the Done action button on the CONNECT screen (and the
devices are already installed), LonMaker
sends connection information to the devices
and removes the+ symbol next to device name.
If the devices are not installed yet, LonMaker
saves the connection information and sends it
to the devices when you do install them.
LonMaker refers to the inputs and outputs of devices as network variables (NVs). Inputs and outputs on a LonWorks network are not hard-wired
connections, but flexible software connections.

The installer selects the Installation task, and
identifies specific device nodes by pressing
their individual service pins when prompted to
do so by the LonMaker installation program.

CONNECT PROCEDURE
This section covers setting up connections between
outputs and inputs of application devices. This process is also referred to as “binding.” (Refer to the
end of each module section for available bindings.)
You can connect application devices before or after
installing them.

The devices you connect must be in the same domain, but they can be in different locations.

Procedure for Manual Connections

Procedure for Connecting Devices

The network designer will provide instructions
and/or forms that define these connections.
(Sample forms and schematics are provided in
the back of this manual.)
From step 7 above: If the selected pair does not
have predefined connections, or if you want to set
up other connections:
1. Click on the Manual action button. The MANUAL CONNECT screen appears (Figure 3-12).
2. Select an output for one device and an input for
the other device. A ♦ symbol appears to the left
of your selections.

1. Click on the Installation task button. (Figure
3-10).
2. Select the specific location that contains the
“hub” device—or select the All location.
3. Select the “hub” device from the Devices list.
The hub device is the device that you will to
connect to several other devices.
4. Click on the Connect (F8) action button. The
CONNECT screen appears (Figure 3-11).
5. Select the next device to connect to from the
Devices list.
6. Choose the Auto or Manual actions.
Auto: If there are automatic (predefined) connections for the two selected devices, this button appears at the bottom of the screen. Click
on the Auto action button to add these connections to the pending list. Refer to Appendix C
for a list of Automatic Connections.
Manual: If the selected pair does not have predefined connections, or if you want to set up
other connections, click the Manual action button. Manual connections are described below.
7. Repeat steps 5 and 6 for each device that connects to the hub device.
8. Click on the Done action button to complete the
pending connections.
9. Repeat steps 2 thru 8 for the next designated
hub device and each of its connected devices.

The inputs and outputs must be of the same
type.
LonMaker checks your choices for connections
to see if a connection is already pending or completed, and whether it is appropriate for the
types of inputs and outputs involved.

3. Choose the Add or Next actions.
Add: Adds the input/output connection to the
list of pending connections.
Next: Toggle the display of inputs and outputs
between the two selected devices.
4. Repeat steps 2 and 3 to set all connections between these two devices.
5. Click on the Done action button to return to the
CONNECT screen. LonMaker completes the
pending connections when you click on the
Done action button on the CONNECT screen.

Before you use LonMaker to install devices on a
network, you must also complete the following
steps:
1. Connect the computer to the Network Installation Gateway.
2. Physically connect the Network Installation
Gateway to the network channel.
3. Turn on the computer and network interface.
4. Start LonMaker.
(From the site directory you created, type:
lnmg)
5. Make sure that LonMaker is “attached” to the
correct channel. Refer to the icon in the upper
right corner of the screen (Figure 3-13) to determine if the Network Installation Gateway is
attached. If it is not attached, click on this icon.
If it will not attach, check the cable connection
to the PC and verify that it is connected to the
correct COM port as identified in the config.sys
file (/P1, /P2, etc.). Also try cycling power on the
Network Installation Gateway and make sure
its service LED blinks once when the power is
cycled On.

INSTALL PROCEDURE
Preliminary Steps
Before you perform these steps, the specific components of the network must be defined. The last
step in setting up LonMaker for network installation
is to identify the channel to which LonMaker is attached. (If the network has only one channel, LonMaker automatically selects this channel.) The setup procedures are covered under LonMaker Network Setup.


Network service procedures can
cause accidental starting of the generator set or
operation of a transfer switch or other auxiliary
equipment connected to the network—which
can cause severe personal injury or death.
Place the generator set RUN/OFF/AUTO switch
in the OFF position. Prevent accidental operation of the transfer switch by disabling the actuating mechanism (see Operator’s Manual).

If the device was previously installed, LonMaker informs the installer that the device has been
configured. Select Continue (F2).

Procedure to Install Devices
In networks with Routers, the order of installation is
important. Install the Router(s) first. Routers connect different channels. Once they are installed the
other channels can be accessed so that modules on
those channels can be installed.

When installation of a device is complete, LonMaker removes the • symbol from the left side of the device name.
Repeat steps 2, 3, 4, and 5 for each device in the
network.

1. Click on the Installation task button (Figure
3-13).

Reset Modules

2. Choose a location for the device. Choose the
All location or the specific location for the device.

When finished using LonMaker, push the reset button on each of the modules.

3. Select the device from the Devices list (Routers
first if applicable). Uninstalled devices have a •
symbol next to their names.

When finished with the installation, make a backup
copy of the entire LonMaker site directory on a separate floppy disk. Keep the LonMaker site directory
structure intact when backing it up.

Make Backup Copies

4. Click on the Install action button. The INSTALL
screen appears.

Use Microsoft Windows File Manager to copy the
site directory and files to the floppy drive. The directory structure MUST be preserved.
Store the backup in a safe place.

5. LonMaker displays a message asking you to
press the service pin on the device to install.
LonMaker waits until you press the service pin
(or until you press the  key to cancel the
process).

 If this database is lost or corrupted,
the entire installation procedure must be repeated. In addition to making and safely storing backup copies, keep documentation of the
network design (device names, connections,
locations, etc.) up to date with the LonMaker database. This is the responsibility of the network
designer and the network installer.

(Service pin location for a specific device is provided in the hardware description of that device.
Make sure that you press the service pin on the
correct device.)

6. After the service pin is pressed, it can take a
few minutes to install the device. Wait until the
LonMaker popup indicates that the device is
successfully installed.

 Network service procedures can
cause accidental starting of the generator set or
operation of a transfer switch or other auxiliary
equipment connected to the network—which
can cause severe personal injury or death.
Place the generator set RUN/OFF/AUTO switch
in the OFF position. Prevent accidental operation of the transfer switch by disabling the linear
actuators.

The Replace action allows you to substitute a new
device for a defective device. You can only replace
one device with an identical device type.
You can also use the Replace action to test a device
that may be defective. Replacing a suspected defective device with a known good device will help
determine whether the original device is defective.
The Replace action installs the new device and
transfers input and output connections, recorded in
the LonMaker database, from the original device to
the replacement device.

Taking Devices Off Line or
Placing Them Online
Using the Offline action, network application devices can be rendered inactive. You may want to
deactivate certain devices while you are troubleshooting a network.

Before you begin a replacement, physically remove
the original device, and replace it with the new device. The replacement device must be installed on
the same channel as the original.

Offline devices receive inputs, but respond only to
an Online or Reset action. The Online action restores the activity of an Offline device.

To execute the Replace action, perform the following steps:
1. Install the replacement device on the network.
2. Click on the Repair task button. The REPAIR
screen appears.

Test Statistics

TESTING DEVICES AND
VERIFYING INSTALLATION
You can test installed and connected devices to see
if they are working properly.

Evaluation of these statistics may be a task for a network designer, system programmer, or network support specialist. For further information, refer to the
Echelon LonMaker Installation Tool Users Guide.

The following steps cover the procedure for testing
a device to determine whether it can communicate—receive and send messages—over the network.

You can further examine the test results by choosing the TEST STATISTICS screen.
1. On the TEST screen, click on the Stats action
button to see the TEST STATISTICS screen.

3. Click on the Test (F3) action button. The TEST
screen appears (Figure 3-17).
The TEST screen displays the following fields:

CRC errors: The number of errors in the message accuracy test (cyclic redundancy check),
detected on receiving a message packet at the
device. These could result from collisions,
noisy communications media, or signal attenuation.

Test Results: PASSED or FAILED refer to
whether or not LonMaker can communicate
with the selected device.

Transaction timeouts: The number of timeouts that occurred while the device tried to
carry out a message transaction.

System Version #: Version of the firmware on
the device’s Neuron chip.

Receive transaction errors: The number of
times the device failed to receive messages
because it had too many pending messages at
one time.

Error: The most recent error message that the
device recorded, if any.
Last Reset: The reason for the last reset. If the
message “Watch-dog timer” occurs repeatedly, the device is defective.

Msgs lost at application level: The number of
messages discarded at the device because its
incoming application buffers were full.

Device State: The activity of the device.
Evaluation of these results may be a task for a
network designer, system programmer, or network support specialist. For further information, refer to the Echelon LonMaker Installation
Tool Users Guide.

Msgs lost at network level: The number of
messages discarded at the device because its

the [Site_id].csv. The .CSV extension stands for
Comma Separated Value. The CSV file must be imported by PCW in order to communicate with the
site.

POWERCOMMAND CONFIGURATION
TOOL (PCT)
This section describes installation and use of the
PowerCommand Configuration Tool software, beginning with version 1.00.
Note: PCT v1.00 will not convert site files that were
created with the Beta Release (v0.914). If site configuration data for all existing sites were recorded on
the Network Design Forms, proceed with the installation. Otherwise, record all configuration data for
each site on the design forms. Do this by running
v0.914, open each site and record all configuration
data. Sites that were configured with v0.914 are still
valid and do not require servicing. However, when
servicing is required on one of these sites, the site
files will have to be recreated. All configuration data
must be re-entered (and re-written) with the new software.

PCW must be updated with the latest .CSV file anytime a module is added or removed from a site, or
the bindings are changed in LonMaker or the configuration is changed in PCT.
In this section, the network installer will install and
use the PCT software to complete the network
installation. To use this software, you will need to
have experience using Windows application software.
Menu commands that are grayed out will not function. If a command is grayed (dimmed) in the menu
bar or pull down menu list, it may not be available at
that time or in the current software version.

PCT is used to complete the installation of a PowerCommand Network. After using the LonMaker
installation software to begin the network installation (Section 3), define and connect modules etc.,
the installer must run PCT. PCT is used to edit and
install the network modules’ configuration settings.
PCT also creates a site information file (.CSV file)
that is used by PowerCommand for Windows
(PCW) software to communicate with the PowerCommand Network.

The forms in Appendix C can be used to predefine
and document the information that will be filled into
the PCT screens. By completing these forms before
using PCT, this process may be easier to complete.
The sections that follow this one (beginning with
Section 5) provide detailed information on each of
the individual modules available for the PowerCommand network.

The site information file (.CSV) contains information
necessary for PCW to communicate with the mod-

parameters.

Configuring a Site
Opening a site (or creating a new site), loads the
Site dialog. There are four buttons allowing the user
to save changes, write configuration to the module,
close the site and get online help.

The software is pre-loaded with five templates for
quickly configuring Cummins/Onan equipment.
These five templates (modules) are found in the
TEMPLATE site. This site is “Read Only”. Applying
a template to a module is accomplished by copying
a module from the TEMPLATE site. (Refer to Edit –
Copy From Site, described earlier in this section).

A box with a plus symbol (+) to the left of the module
icon indicates the module has parameters to be
configured. An empty box indicates the module has
no configurable parameters.

The following section describes how to navigate the
configure site dialog and how to configure modules.

Configuration information may be entered manually
as described in the following sections or copied
from another module (which has already been configured). To copy a module’s configuration information to another module, drag the module which has
already been configured (source) on top of the module which you want to configure (target) and drop it.
You must confirm your action.

To configure a module, click on the plus symbol (+)
or double click on the module icon or name. The
module list is expanded, listing its configurable parameters. Once expanded, A minus symbol (–) appears in the box to the left of the module allowing the
user then “contract” the module. Selecting a parameter will display its configurable fields below. When
displayed, the user may edit the parameter(s).

The source module may be in the same site or in
another existing site. The target module cannot be
in a site which has been opened as “Read Only”.

ADDITIONAL INSTALLATION STEPS
After using PCT to configure a site, always perform
these steps before testing out a network installation.



Do not use the “installation” computer to run PCW unless it has been disconnected from the Network Installation Gateway
and reconnected to the site monitoring NGM.

Reset Modules
When installation and configuration are complete,
each of the modules (nodes) must be reset. This
can be done by pressing the reset button on each
module or with the reset feature in PCT. In PCT, attach to the site, select a module and click on the Reset button. Repeat this step for each module.

Refer to the PCW manual (900-0365) for instructions on installing and running PCW. Operate PCW
to thoroughly check out the installation.
If installation problems are detected, reattach to the
site through an Installation Gateway before running
LonMaker or PCT. Failure to use a Network Installation Gateway will cause the NV data stored in the
site NGM to be destroyed.

Repower NGM
Turn Off the NGM power switch, then turn it back
On.
Note: A connection problem can occur with
some computers when exiting PCT in Windows
95 to run LonMaker. If LonMaker will not attach
to the Network Installation Gateway, Windows
95 may not be releasing the port.

Each time a change is made in LonMaker (such as
adding a module, repairing or replacing a module,
or changing bindings) a new .CSV file is required for
PCW. Open the site in PCT to create the new .CSV
file.

If this occurs, the port will need to be disabled
and re-enabled. Use Device Manager, located in
the System folder of Control Panel, in Windows
95. Under Ports, select the COM port that the
Network Installation Gateway is attached to and
select Properties. Under Device Usage, unselect the check box to disable the port, then click
OK. Repeat this procedure and click on the
check box to select it and enable the COM port,
then click OK.

CHANGES TO THE LONMAKER
DATABASE
After a site has been updated with LonMaker (added, removed, replaced, or installed modules), PCT
should be run to update the site’s configuration.

INSTALLATION CHECKOUT

In PCT, open the site as normal. Each time PCT
opens a site it checks the site directory to see if any
changes have been made to the site. If changes to
the site are detected, PCT will display a message
stating the user must update the modules at the site
(Figure 4-36). The PCT Database Discrepancies
dialog will open, listing all the old and new modules
at the site. Next to each module name is a unique
identification number. No two modules will have the
same identification number.

Make Backup Copies
Use File – Export Site to make a complete backup
copy of the LonMaker site directory (the exported
file [file.pct] will be located in C:\ONAN\PCT\EXPORTS). Also make a separate backup copy of the
CSV file (located in C:\ONAN\PCT\CSV). Keep a
copy of all of the “Binding Forms” used to describe
the modules and connections etc., (see Appendix

Pairing Unpaired Modules

 Old Unpaired Module configuration
will be lost if not paired.

The Discrepancies dialog (Figure 4-37) provides
the option to manually “Pair” each old module configuration with a new module. This allows the user
to retain a module’s configuration. This is needed
after configuring a site in advance of installing it. Or
if a module has been physically replaced and the
user would like to write the identical configuration to
the new hardware.

To Pair Modules: In the Unpaired Modules section,
click on the module in the Old Modules dialog, then
click on the module in the Current Modules dialog.
Click on the Pair button to pair the modules.
To Unpair Modules: To undo a pairing, select the
two modules you want to unpair from the Paired
Modules section and press the Unpair button.
When finished pairing modules, click on the Done
button. Modules which have been paired will retain
their configuration. All unpaired New Modules will
be added to the site with their default configuration
while all unpaired Old Modules will be removed
from the site. Make sure the monitoring PC updates
its site information with the latest site information file
(.CSV file).

To retain a module’s configuration, pair the old module with the new one. This is done by selecting a
module from the Unpaired Modules (Old Modules)
list and then selecting the corresponding module in
the Current Modules list. Then press the Pair button. This will move the two modules to the Paired
Modules section.

OVERVIEW

DESCRIPTION
The GCM is mounted inside the PCC housing. It is
required for connection of the PCC to the PowerCommand Network. Control and monitoring of the
PCC can be accomplished over the network, via the
GCM.
The GCM contains a terminate circuit for use at the
end of a network data bus.
The GCM provides an interface for data from the
PCC to other modules on the network. The GCM
communicates with the PCC via the engine interface board, and it monitors various PCC circuits to
determine the operating state of the control. For example, the GCM stores PCC data such as volts, current, engine speed, and oil temp; and then sends it
out on the network when another network node requests the data.
Outputs from the GCM allow it to “wake up” the PCC
when needed, or to cause an emergency shutdown
on command. The GCM also provides some direct
local control and monitoring of the PCC. It monitors
for Not-In-Auto mode and High and Low battery
voltage (when the PCC is asleep).
The GCM is powered from the genset battery. It remains powered even when the PCC is “asleep.”

This section describes the Genset Communications Module (GCM) and its functional role in the
PowerCommand Network. This section also describes the physical mounting and wiring of this
module, and provides information for the logical
installation and connection of the GCM on the network.
In network terms, “logical installation and connection” refers to programming the various devices (or
nodes) on the network so that they can communicate with one another. This communication takes
the form of passing network variables from one device to another. The process of assigning connections—linking an output variable of one device to an
an input variable of another device—is called “binding.”
In addition to functional and physical descriptions,
this section provides definitions of the network input
and output variables assigned to the GCM. Refer to
section 3 for the step-by-step procedure for binding
these variables to input and output variables assigned to other network devices.

Block Diagram

Refer to Mounting in this section for GCM compatibility with PCC software versions.

Refer to Table 5-1 and Figure 5-1 for a block diagram overview of the GCM.

Description/Specification

B+ Power

This is an output from the PCC to the GCM. The digital and analog circuitry on
the GCM is powered from CNTRL B+ from the PCC. The GCM is always powered. It rides through starter dip and crank. The GCM is switch selectable for
12V or 24V systems.

Serial Data

This is a bidirectional data path between the PCC and GCM. The GCM communicates with the PCC through the PCC’s serial port. Communication rate is
2400 baud. Starting, stopping and exercising of the set, readout of AC data,
Engine data, and Set status information are done through this link.
NOTE: When the PCC’s service port is connected (serial port) to an external device, the GCM cannot communicate with the PCC and thus the PCC
state and data cannot be known on the network.

Emergency Stop
Control

This is an output from the GCM. The GCM can activate the PCC’s Emergency
Stop Latching Relay. This allows a remote emergency stop over the network.
NOTE: The Emergency Stop condition can only be reset at the PCC front
panel. Can be reset once the E-Stop output from the GCM has been
cleared.

Wake Up Monitor
and Control

This is both an output and an input for the GCM. The GCM has the capability to
wake up the PCC. It would do this for example when a network message was
telling the genset to start. The GCM also has the capability to monitor whether
or not the PCC is awake (i.e. due to some other reason). This helps the GCM
determine if it can communicate with the PCC.

B+ Voltage Sensing

This is an input to the GCM from the PCC. The GCM directly monitors battery
voltage and determines high and low conditions. This function is needed when
the PCC is not awake (and thus is not capable of monitoring battery voltage
itself). A low or high condition will cause the GCM to wake up the PCC. The
PCC then annunciates the warning. Voltage thresholds are the same as in the
PCC. The GCM annunciates to the network a high or low voltage condition.

Not-In-Auto Monitor

This is an input to the GCM from the PCC. The GCM monitors the position of
the front panel Run/Off/Auto switch. When the PCC is not awake, the GCM
annunciates to the network a Not-In-Auto condition.

than the version listed, obtain and install an
EPROM upgrade kit.

MOUNTING
GCM is mounted inside PCC cabinet on top of the
analog board (Figure 5-2).

Special Tools Required
• Grounding wrist strap with grounding clip

 Electrostatic discharge will damage
circuit boards. Do not remove the circuit board
from the antistatic shipping bag until you are
grounded to the PCC with a wrist strap.

Circuit Board Handling Precautions
To help prevent circuit board damage due to electrostatic discharge (ESD), a grounding wrist strap
must be worn when handling the circuit board. (The
wrist strap does not provide a direct short to
ground, it is typically rated at approximately 1 megohm to ground.)

The GCM must be used with PCC operating software version 1.06 or newer for all models except
DFHA, DFHB, DFHC and DFHD (these models
have unique operating software and are GCM compatible with version 1.04 or newer). Check the version on the display menu. If the version is earlier

Attach the clip to a clean unpainted surface of the
control box (see Figure 5-2) and place the strap
around your wrist before handling a circuit board.

INSTALLATION
1. Place the genset Run/Off/Auto switch, on the
control panel, in the Off position.
2. Disconnect the battery charger (if applicable).
Remove all electrical supply sources.
 Always disconnect a battery
charger from its AC source before disconnecting the battery cables. Otherwise, disconnecting the cables can result in voltage
spikes high enough to damage the DC control circuits of the system.

 "
 !


3. Disconnect the genset starting battery
cable(s). Disconnect the negative (–) cable(s)
first to reduce the risk of arcing.


Accidental starting of the genset while working on it can cause severe
personal injury or death. Prevent accidental starting by disconnecting the starting
battery cables. To reduce the risk of arcing,
disconnect the negative (–) cable first.
When reconnecting, connect the negative
(–) cable last.
Make certain battery area has been wellventilated before servicing battery. Arcing
can ignite explosive hydrogen gas given off
by batteries, causing severe personal injury. Make certain hydrogen gas, engine fuel,
and other explosive fumes are fully dissipated. This is especially important if battery
has been connected to a battery charger.

FIGURE 5-3. PREPARING TO MOUNT GCM BOARD

4. Open the control box door. Connect the wrist
strap ground clip as shown in Figure 5-3.
5. Use a Phillips screwdriver to remove the four
analog board mounting screws shown in Figure 5-3.
6. Install four new standoffs in place of the analog
board mounting screws removed in step 5
(Figure 5-4). Tighten the standoffs securely.

and output variables assigned to the DIM. Refer to
section 3 for the step-by-step procedure for binding
these variables to input and output variables assigned to other network devices.

OVERVIEW
This section describes the Digital I/O Module (DIM)
and its functional role in the PowerCommand network. It also describes the physical mounting and
wiring of this module, and provides procedures for
the logical installation and connection of the DIM on
the network.

DESCRIPTION
The DIM provides a group of relay contact outputs
and discrete inputs for interfacing the PowerCommand Network to alarm or status outputs and to
equipment that does not have compatible communications capability.
The DIM contains a terminate circuit for use at the
end of a network data bus.
The DIM provides16 Form-C relay contacts, which
are driven by data from the network. The contacts
are connected to terminal blocks for field wiring.
Each relay can be programmed to operate from
connectable variables on the network. The module
also includes four isolated digital inputs to couple
user inputs to the network for additional control and
monitoring.

In network terms, “logical installation and connection” refers to programming the various devices (or
nodes) on the network so that they can communicate with one another. This communication takes
the form of passing network variables from one device to another. The process of assigning connections—linking an output variable of one device to an
an input variable of another device—is called “binding.” Refer to Appendix C for Application Table Consumption to review the number of connections that
can be made.
In addition to functional and physical descriptions,
this section provides definitions of the network input

Power Supply

Outputs

The DIM requires power from the network power
bus. Power supply wiring and connection is covered
under Wiring and Cabling in Section 2. See Figure
6-5 for minimum power input.

The DIM provides sixteen 5A, 250VAC/30VDC
Form-C dry contact latching relay outputs. Secure
wires in the terminal block to 2 inch-lbs. (0.23 NSm).
External devices that are wired to these relays
should be fused appropriately to prevent damage to the DIM.

Inputs
Four discrete inputs can be connected to external
dry contacts. These inputs must be referenced back
to either of two “input common” terminals through

OVERVIEW
This section describes the Network Gateway Module (NGM) and its functional role in the PowerCommand Network. It also describes the physical
mounting and wiring of the NGM, and provides procedures for the logical installation and connection of
the NGM on the network.

The NGM (Figure 7-2) has an RJ45 connector on
one end for connection to network data. It has a DB9
connector on the other end for connection to an
RS–232 port on a PC or to an RS-232 port on a modem.
Externally the NGM has a DC power input jack, an
ON/OFF switch, a SERVICE pushbutton, and a
SERVICE LED indicator.

DESCRIPTION
The NGM provides a PowerCommand Network interface to a PC, either directly or through a modem.
The NGM translates network protocol into a protocol that a PC can understand. Figure 7-1 is a block
diagram of the NGM.

The NGM does not contain a terminate circuit for
use at the end of a network data bus. If the NGM is
located at the end of the network data bus, use a
JBT to connect the NGM and set the JBT to terminate.

Power Supply

The NGM allows software running on a PC to access, poll, and control all devices on a network.
PowerCommand Software for Windows (PCW)
uses this device to access the network. In this application the NGM is referred to as a “Network Gateway Module.”

The NGM has a DC power input jack, that connects
to utility power through a plug-in transformer.
If the NGM must remain powered during an electrical power failure, use an Uninterruptable Power
Supply (UPS). Refer to the UPS section of this
manual. If more than one device will be connected
to the UPS, purchase a multi-outlet adapter or multioutlet extension cord.

LonMaker and PowerCommand Configuration Tool
software require an NGM for installing a network
(referred to as a “Network Installation Gateway.”)

WIRE CABLES
 Use only the custom made cables
that are supplied with this kit. Cables from a
computer supply store may look the same, but
they may cause equipment damage or connection problems.

Figure 7-2 shows the network gateway module outline dimensions and connection points.
The module can be placed on a clean flat surface or
it can be mounted to a wall or other flat surface with
mounting brackets. Figure 7-3 shows the outline
and mounting hole locations for the mounting
brackets.

Figure 7-4 shows each of the cables included in this
kit.
These cables provide the following interconnects:
S Network Gateway Module to a modem
S Network Gateway Module to a PC
S Network Gateway Module to a Junction Box/
Terminator Module or other network RJ45 connection

If mounting to the wall, make sure that no wires,
plumbing, gas or exhaust lines run behind the wall
before drilling mounting holes.
The foam tape on the brackets is for spacing the
brackets. The exposed covering can be removed to
adhere the foam spacer to the NGM.

Only one of the top two cables shown in figure 7-4
will be used. The cables selected will depend on the
application.

OVERVIEW

the network bus. Termination of nodes at the
ends of the network is required.

A Junction Box/Terminator (JBT) is a device that
provides connection points for network power and
data wires. The JBT contains a terminate circuit for
use at the end of a network data bus. JBTs may be
used throughout a network for connecting in Pass
Thru or Local Loop configurations. A JBT is required to connect an NGM to the end of a network
data bus.

DESCRIPTION
The JBT provides two 6-position pluggable terminal
blocks for data and power (J1 and J2), and two
RJ45 jacks for 24AWG stub connections (J3 and
J4). The JBT also has a switch (S1) to connect the
data lines to a terminator circuit, and a switch (S2) to
select either Pass Thru or Local Loop connection
between the data lines on the two terminal blocks.

The JBT is used to provide a network termination for NGM nodes that are located at an end of

OVERVIEW
This section describes the Network Annunciator
Module (NAM) and its functional role in the PowerCommand network. It also describes the physical
mounting and wiring of this module, and provides
procedures for the logical installation and connection of the NAM on the network. Refer to the Network Annunciator Operator’s Manual 900-0282 for
features, customer options and operating procedures.
In network terms, “logical installation and connection” refers to programming the various devices (or
nodes) on the network so that they can communicate with one another. This communication takes
the form of passing network variables from one device to another. The process of assigning connections—linking an output variable of one device to an
an input variable of another device—is called “binding.” Refer to Appendix C for Application Table Consumption to review the number of connections that
can be made.
The NAM contains a Digital I/O Module that provides a communications interface with other modules on the network. Refer to the Digital I/O Module
section for network input and output variables assigned to the Digital I/O Module. Refer to Section 3
for the step-by-step procedure for binding these
variables to input and output variables assigned to
other network devices.

FIGURE 9-1. ANNUNCIATOR

DESCRIPTION
The NAM shown in Figure 9-1, combines a hardwired PowerCommand System Annunciator with a
Digital I/O Module. The NAM is connected to the
network by twisted pair data wire.
The NAM contains a terminate circuit for use at the
end of a network data bus.
The NAM has 20 LEDs to annunciate alarms. In
NFPA 110 applications the network directly controls
16 of the LEDs and indirectly controls one LED
(DS3), refer to Table 9-4). The remaining three
LEDs can be hardwired. In non-NFPA 110 applications the network controls 16 of the LEDs and four
can be hardwired.
The Digital I/O Module also includes four isolated

WIRING DIAGRAM

Four digital inputs can be connected to external dry
contacts (J1-1 thru J1-4). These inputs must be referenced back to either of two “input common” terminals through dry contacts (see note 2 on Figure
9-4). Three customer faults and one customer indication can be connected to the negative logic annunciator. These inputs must be referenced back to
ground (TB1-24) through dry contacts (see notes 5,
6 and 15 on Figure 9-4).
TB1-20 can be used as both input and output for Silence/Lamp test (see notes 5 and 6 on Figure 9-4).

Figures 9-4 and 9-5 show the interconnect wiring
diagram and associated notes for the network annunciator module. Refer to the specifications and
notes on the drawing. The DIM is prewired to the
negative logic annunciator. Refer to the NAM Operator’s Manual (900-0282) for complete wiring information.

Power Supply
The Network Annunciator Module requires network
power. Power supply wiring and connection is covered in Section 2. See Figure 9-4 for minimum power input.

Outputs
Two Form C relays (K1 and K2) are available for remote Silence/Lamp Test and Remote Alarm. Both
sets of contacts provide ground to an external circuit and are rated at 2 amps maximum at 30 VDC

dix E. The spare analog inputs are for signal monitoring (4-20 mA, 0-1 mA, 0-5V). The three temperature inputs and the oil pressure input can be used
generically with any sensor that provides between
0-9 VDC.

OVERVIEW
This section describes the Controls Communications Module (CCM) and its functional role in the
PowerCommand network. This module is used to
monitor and control both gensets and automatic
transfer switches. This section describes the CCM
and applications involving gensets. This section
also describes the physical mounting and wiring of
this module, and provides procedures for the logical
installation and connection of the CCM-Genset on
the network. Section 11 describes automatic transfer switch applications.

The 32 discrete inputs permit monitoring of numerous status/fault conditions. These inputs must be
referenced back to either analog ground (J6) or net
power negative (–) through dry contacts or through
a pulldown resistor when active “OPEN” input is +5
to +36 VDC (see notes 6 and 17 in Figure E-5).
The values of the analog and discrete inputs are
read from the network.

In network terms, “logical installation and connection” refers to programming the various devices (or
nodes) on the network so that they can communicate with one another. This communication takes
the form of passing network variables from one device to another. The process of assigning connections—linking an output variable of one device to an
an input variable of another device—is called “binding.” Refer to Appendix C for Application Table Consumption to review the number of connections that
can be made.

The CCM contains a terminate circuit for use at the
end of a network data bus.

CCM Outputs
The CCM has two Form-C relay outputs, and two
Form-A relay outputs. The relays are controlled
from the network and are used to transmit start/
stop/reset control signals.
External devices that are wired to these relays
should be fused appropriately to prevent damage to the CCM.

In addition to functional and physical descriptions,
this section provides definitions of the network input and output variables assigned to the CCM-Genset.

Standard Displays
Solid state indicators are provided to aid in diagnosis of module operating status. These include a service LED for the Neuron chip and a running LED on
the main processor.

DESCRIPTION
The CCM can be used to monitor and control a conventional (non-microprocessor controlled) genset.
It provides a PowerCommand Network interface for
remote monitoring and control.

CCM Power Supply
For genset applications, the 12- or 24-volt set starting battery(ies) will be used to power the CCM. The
genset must have a battery charger capable of
maintaining the starting battery(ies) with the CCM
load.

The module can monitor digital inputs, and AC and
DC analog inputs from generator sets and communicate monitored data to the PowerCommand network. Relay outputs on the CCM provide a limited
amount of control of the monitored equipment from
the network. For example, these outputs can be
used to remotely start a generator set.

Refer to Section 2 for a detailed description of Network Power and Network Power Wire Sizing requirements.

The CCM has 16 channels of analog input and 32
digital inputs. Most of the analog channels are configured for specific types of signals (AC volts, current, phase, oil temp, oil pressure, coolant temp, exhaust temp, etc.,see Figures E-4 and E-5 in Appen-

CCM CONTROL BOX MOUNTING
Figure 10-3 shows the CCM control box outline dimensions. The outside dimensions do not include
clearance for wire connections (dependant on conduit size and routing). When the mounting location
and wire routing are determined (see Wiring Connections section), make holes in the control box for
AC, DC, and data wire routing. Be careful not to
damage the CCM module. Remove the CCM if drilling is required. If the CCM is removed during
mounting, make sure the ground lead is recon-

 Installation debris can cause equipment failure and damage. Use extreme care to
keep drill chips and filings out of the CCM control box. Use tools carefully to prevent damage
to components.

Make sure that no wires, plumbing, gas or exhaust
lines run behind the wall before drilling the mounting
holes.

WIRE AND CONDUIT

WIRING CONNECTIONS

Measure the distance, one way, between the CCM
mounting location and the genset control. Refer to
the wire size chart in Figure E-13 (in Appendix D) to
determine the appropriate wire gauge for CT wires,
power supply wires and monitor and control wires
(see Table 10-2 for additional CT wire information).
Use stranded wire with a minimum insulation rating
of 600V and a temperature rating of 105°C.

This section describes connecting the CCM to a
genset with a Detector or DK type of control. Figures E-13 and E-14 show the interconnect wiring
diagram specifically for the CCM to Detector or DK
control. (Figures E-13 and E-14 apply to both 7-light
and 12-light Detector controls. Connections for Low
Fuel, Low Engine Temp, Fault1 and Fault2 are not
available from the 7-light control.)
Figures E-4 and E-5 provide basic CCM interconnect wiring diagram information, review the notes
on figures E-4 and E-5 and use these drawings for
reference.

Run one conduit for the AC wire connections and a
second conduit for the DC wire connections between the CCM and the genset control box. The
data wire does not require conduit unless mechanical protection is desired. The data wire can be
strapped to the outside of the DC conduit and be run
into the control box through a rubber grommet.
Make sure wiring meets all applicable wiring codes.

 Accidental starting of the generator
set while working on it can cause severe injury
or death. Disconnect the battery cables to prevent accidental starting. Be sure to move the
generator set operation selector switch to Stop,
disconnect the battery charger, disconnect the
starting battery (negative [–] lead first).

Install at least 2 feet (610 mm) of flexible conduit on
both lines at the genset control box connection to allow for genset vibration during operation. Round off
or cover the ends of the conduit to prevent sharp
edges from cutting the insulation. Use waterproof
conduit if the CCM will be exposed to moisture.

 Ignition of explosive battery gases
can cause severe personal injury. Do not smoke
or cause any spark or flame while servicing batteries.

The number of leads pulled through each conduit
will be determined by the type of genset control and
the desired monitor and control features selected.
Refer to the table in Figure E-14 for a list of the possible AC and DC connections. Number both ends of
each lead for identification before pulling the wire
through the conduit.

 Always disconnect a battery charger from its AC source before disconnecting the
battery cables. Otherwise, disconnecting the
cables can result in voltage spikes high enough
to damage the DC control circuits of the generator set.

1. Before making any wiring connections, make
sure the genset cannot be started by moving
the RUN/STOP/REMOTE switch to STOP.
Disconnect the power to the battery charger
and disconnect the starting battery (negative
[–] battery cable[s] first).

Grounding must comply with all codes. Mount the
enclosed ground lug inside the mounting box (refer
to the instructions provided with the lug). Make sure
the paint is removed from the ground lug mounting
location to provide a good ground.

control box, provide enough wire so that the
leads can be secured to the existing harness.
Leads that connect to components on the control panel door should be routed near the
hinges and be secured to the existing leads.

2. Refer to Figures E-13 and E-14 for point-topoint wiring information and component and
terminal locations. Follow standard wiring
practices. Properly secure wire terminals when
needed. Secure wires in the CCM terminal
blocks to 2 in-lbs. (0.23 NSm). Observe wire
gauge requirements for CT wires, power supply wires and monitor and control wires.

5. Connect the data wire to the CCM and provide
an adequate length of twisted pair wire for future connection to a junction box. Tighten the
tamperproof control box mounting screws securely to prevent tampering.
6. The module is now ready for network wiring.
Network wiring must be done by a trained network installer. Refer to sections 2, 3 and 4 for
instructions on network wiring the CCM and for
installation and connection of this module to
the network.
7. When the network installation is complete, reconnect battery (negative [–] battery cable[s]
last), reconnect battery charger and return the
generator control switch to the Remote position.

3. The table in Figure E-13 identifies the DC and
AC connections. The DC leads must be run inside a separate conduit from the AC leads.
It may be easiest to start at the top of the table
with the DC connections and make all the connections inside the CCM control box. Then
move to the genset control to complete the wiring. Make sure that each lead is marked and
pay close attention to the associated notes in
the wiring table. Some connections are for
jumpers inside the CCM only.

NETWORK POWER
Refer to Section 2 for information on the network topology and data transmission media. Also refer to
Section 2 for network power supply wiring calculation procedures.

NETWORK DATA MEDIA
AND POWER WIRING
 AC voltages and currents present
an electrical shock hazard that can cause severe personal injury or death. Only trained, experienced personnel are to perform the following procedures.

Connections
Network data and power wiring connections are
made at connector J9.

Conduit
When installing conduit, observe the following precautions:
1. Before beginning conduit installation, cover all
components to prevent accidental entry of metal chips.
2. If using rigid conduit, install at least 2 feet (610
mm) of flexible conduit between the rigid conduit and generator set to absorb vibration.
3. Always run DC circuit wiring in a separate metal conduit from AC power cables to avoid in-

ducing currents that could cause problems
within the control.
4. Data wire can be run without conduit if it is adequately protected. Do not run data wire in conduit with network power wiring or other nonpower–limited circuits. Make sure wiring meets
all applicable wiring codes.
 Installation debris can cause
equipment failure and damage. Use extreme care to keep drill chips and filings out
of the components when mounting or connecting conduit. Screwdrivers should be
used carefully to prevent damage to components.

The 32 discrete inputs permit monitoring of numerous status/fault conditions. These inputs must be
referenced back to either analog ground (J6) or net
power negative (–) through dry contacts or through
a pulldown resistor when active “OPEN” input is +5
to +36 VDC (see notes 6 and 17 in Figure E-5).

OVERVIEW
This section describes the Controls Communications Module (CCM) used for monitor and control in
automatic transfer switch applications (CCM-ATS).
This section describes the physical mounting and
wiring of this module, and provides procedures for
the logical installation and connection of the CCMATS on the network.

The values of the analog and discrete inputs are
read from the network.

CCM Outputs

In network terms, “logical installation and connection” refers to programming the various devices (or
nodes) on the network so that they can communicate with one another. This communication takes
the form of passing network variables from one device to another. The process of assigning connections—linking an output variable of one device to an
an input variable of another device—is called “binding.” Refer to Appendix C for Application Table Consumption to review the number of connections that
can be made.

The CCM has two Form-C relay outputs, and two
Form-A relay outputs. The relays are controlled
from the network and are used to transmit Remote
Test, Transfer Inhibit, and Load Shed control signals.
External devices that are wired to these relays
should be fused appropriately to prevent damage to the CCM.

CCM Power Supply

In addition to functional and physical descriptions,
this section provides definitions of the network input and output variables assigned to the CCM-ATS.

The CCM power supply consists of a sealed 12-volt
battery and a battery charger. These parts are included in the kit and are located inside the CCM
control box. A separate 120 VAC source is needed
to power the battery charger. If a utility outlet is not
available, a transformer kit is available for obtaining
120 VAC from the ATS.

DESCRIPTION
The CCM-ATS can be used to monitor and control a
transfer switch. It provides a PowerCommand
Network interface for remote monitoring and control. The relay outputs of the CCM provide control of
the transfer switch from the network.

The battery should be replaced every two years.
Make a note in the Maintenance section of the ATS
Operator’s Manual, or add this information to a
master maintenance schedule for the facility. Maintain power to the circuit during battery replacement
by connecting the new battery in parallel with the
power supply circuit, then disconnect the old battery. If a low battery condition is being monitored,
this will prevent a low battery alarm signal.

The CCM contains a terminate circuit for use at the
end of a network data bus.

CCM Inputs
The CCM has 16 channels of analog input and 32
digital inputs (refer to Figures E-4 and E-5 in Appendix E).

Standard Displays
Solid state indicators are provided to aid in diagnosis of module operating status. These include a service LED for the Neuron chip, a running LED on the
main processor.

Most of the analog channels are configured for specific types of signals (AC volts, current, power factor, oil temp, oil pressure, coolant temp, exhaust
temp, etc). The spare analog inputs are for signal
monitoring (4-20 mA, 0-1 mA, 0-5V). The three temperature inputs and the oil pressure input can be
used generically with any sensor that provides between 0-9 VDC.

WIRE AND CONDUIT

WIRING CONNECTIONS

Measure the wiring distance, one way, between the
CCM mounting location and the ATS connection
points. Refer to notes 7 and 8 in Figure E-9 to determine the appropriate wire gauge for CT, monitor
and control wires (see Table 11-2 for additional CT
wire information). Use stranded wire with a minimum insulation rating of 600V and a temperature
rating of 105°C.

Figures E-9 thru E-12 show the interconnect wiring
diagram for connecting the ATS to the CCM. Refer
to the notes on these drawings. Figures E-4 and E-5
provide basic CCM interconnect wiring diagram information. Review the notes on these drawings and
use these drawings for reference. Follow standard
wiring practices. Properly secure wire terminals
when needed. Secure wires in the CCM terminal
blocks to 2 in-lbs. (0.23 NSm).

Run one conduit for the AC wire connections and a
second conduit for the DC wire connections between the CCM and the ATS. Round off or cover the
ends of the conduit to prevent sharp edges from cutting the insulation. Use waterproof conduit if the
CCM installation will be exposed to moisture. The
data wire does not require conduit unless mechanical protection is desired. The data wire can be
strapped to the outside of the DC conduit and be run
into the control box through a rubber grommet.
Make sure wiring meets all applicable wiring codes.

 The transfer switch presents a
shock hazard that can cause severe personal
injury or death unless all AC power is removed.
Disconnect both the Normal and the Emergency
power sources from the transfer switch. Be sure
to move the generator set operation selector
switch to Stop, disconnect the battery charger,
disconnect the starting battery (negative [–]
lead first), and disconnect AC line power before
beginning the installation.
 Ignition of explosive battery gases
can cause severe personal injury. Do not smoke
or cause any spark or flame while servicing batteries.

The number of leads pulled through each conduit
will be determined by the features available on the
ATS and the desired monitor and control features
selected. Refer to Figures E-9 thru E-12 for a list of
the possible AC and DC connections. Number both
ends of each lead for identification before pulling
the wire through the conduit.

 Always disconnect a battery charger from its AC source before disconnecting the
battery cables. Otherwise, disconnecting the
cables can result in voltage spikes high enough
to damage the DC control circuits of the generator set.

Grounding must comply with all codes. Use the
ground lug located inside the CCM control box.

2. If a 120 VAC outlet is available for the charger,
make a hole in the control housing and route
the power cord to the outlet.

1. Disconnect both the Normal and the Emergency power sources from the transfer switch.
2. If a generator set provides Emergency power,
make sure that the generator set cannot be
started by moving the selector switch to Stop.
The selector switch is located on the generator
set control panel on two-wire start systems and
inside the transfer switch cabinet door on
three-wire start systems. If there is an external
battery charger, disconnect it from its AC power
source. Then disconnect the set starting battery(ies) (negative [–] lead first).

If a power source is not available, refer to the
instructions in the transformer kit.

3 Remove the accessory panel cover on the
back of the cabinet door.

PREPARE CCM POWER SUPPLY
A separate 120 VAC source is needed to power the
battery charger. If a utility outlet is not available, a kit
is available for obtaining the voltage from the ATS.
1. Install the enclosed 3-amp fuse in the location
as shown in Figure 11-2. An arc may occur
when the fuse is installed, this is normal.

ing features that require CTs (i.e. current, power factor, etc.), a separate CT kit is required.

4. Refer to the interconnect wiring diagrams (Figures E-9 thru E-12). Note that Figure E-9 is for
switches without meters and Figure E-10 is for
switches with meters. Locate the wiring termination points inside the transfer switch. Identify which installed options are available for
monitoring and control.

7. Position and secure the accessory panel cover.
8. Close and lock the cabinet door.
9. Connect the data wire to the CCM and provide
an adequate length of twisted pair wire for future connection to a junction box or other network module. Tighten the tamper-proof control
box mounting screws securely to prevent tampering.

5. Refer to the outline drawing provided with the
transfer switch to locate and make knockouts
for the wire routing to the CCM. Plan the wire
routing so the monitor and control leads from
the CCM follow the existing harness leads.
Provide adequate wire protection at the knockout. Follow standard wiring practices. Wiring
must meet all applicable codes.

10. Connect the normal AC power source, connect
the genset starting battery(ies) (negative [–]
lead last), and return the genset control switch
to the Remote position. Connect the battery
charger, if applicable.

6. Observe minimum wire gauge requirements
for CT, monitor and control wiring. Connect the
monitor and control wires to the locations
shown in Figures E-9 and E-10. Provide
enough wire so that the leads can be secured
to the existing harness.

11. The CCM is now ready for network wiring. Network wiring must be done by a trained network
installer. Refer to sections 2 and 3 for instructions on network wiring the CCM and for installation and connection of this module to the network.

The CT wiring shown in Figure E-9 is for transfer switches that do not have meters. If monitor-

3. Always run DC circuit wiring in a separate metal conduit from AC power cables to avoid inducing currents that could cause problems
within the control.
4. Data wire can be run without conduit if it is adequately protected. Do not run data wire in conduit with network power wiring or other nonpower–limited circuits. Make sure wiring meets
all applicable wiring codes.

NETWORK TOPOLOGY AND DATA MEDIA
Refer to Section 2 for information on the network topology and data transmission media.

NETWORK POWER
The CCM-ATS receives its network power from a
sealed 12-volt battery and a battery charger. These
components are included in CCM control box. A
separate 120 VAC source is needed to power the
battery charger. If a utility outlet is not available, a
transformer kit is available for obtaining the voltage
from the ATS. Refer to the transformer kit for transformer installation and power supply wiring information.

 Installation debris can cause
equipment failure and damage. Use extreme care to keep drill chips and filings out
of the components when mounting or connecting conduit. Screwdrivers should be
used carefully to prevent damage to components.

OVERVIEW
This section describes the PowerCommand Network Router (RTR) and its use in a PowerCommand
Network. It also describes the physical mounting
and wiring of the Router, and provides procedures
for the logical installation and connection of a Router within the network.

DESCRIPTION
A Router connects two communications channels
by passing messages between the two channels.
The PowerCommand Network Router is configured to connect two twisted pair/transformer isolated 78kb (TP/XF-78) channels.

FIGURE 12-1. NETWORK ROUTER

In addition to extending the length of a network and/
or increasing the number of nodes, Routers can
also be used to improve the reliability of the overall
network. When connecting two or more channels in
a network, each channels is physically isolated so a
failure in one channel will not affect the other channels.

The Router, shown in Figure 12-1, can be used
within a PowerCommand Network to extend the
physical length of the network beyond 4600 feet
(1402 m) and/or increase the maximum number of
nodes to more than 44 nodes.
Two separate (physical and logical) TP/XF-78
channels must be defined, and at least one
installed, before installing the router. Both channels
must be properly terminated at each end (four terminations total). The router must also be installed
before installing nodes that are physically located
on the other side of the Router. Each additional
Router adds one more channel.

Power Supply
The Router has a 9 VDC input power jack, that connects to utility power through a plug-in transformer.
The Router will not operate when utility power is lost
(no messages are passed).
If the Router must remain powered during an electrical power failure, use an Uninterruptible Power
Supply (UPS). Refer to the UPS section of this
manual. If more than one device will be connected
to the UPS, purchase a multi-outlet adapter or multioutlet extension cord.

Each PowerCommand Network is limited to a maximum of 20 channels. Each channel is limited to
4600 feet (1402 m) with a maximum of 44 nodes.

Redistribution or publication of this document,
by any means, is strictly prohibited.

Figure 12-2 shows the Router outline dimensions.

LOCATION
Locate the Router near an electrical outlet.

Refer to section 2 for network topology and maximum network length. All wiring must follow a specific network topology and must fall within distance limits.

Choose a clean, vibration-free mounting surface.
Avoid locations that are hot, damp or dusty. The
temperature range must not exceed 32°F (0°C) to
131°F (55°C).

cal (and logical) channels. Each channel requires
termination at each end of the channel.

ROUTER WIRING
Two Junction Box/Terminator (JB/T) modules are
required to connect the two channels to the Router.
The Router may connect to the end of a channel
(see CHANNEL A) or any convenient point on the
channel (see CHANNEL B).

Each additional channel is limited to 4600 feet
(1402 m) and a maximum of 44 nodes. Routers are
not required for a network that are less than 4600
feet (1402 m) and have no more than 44 nodes.
Each Router allows one additional channel in the
network. PowerCommand Networks are limited to a
maximum of 20 channels.

Routers are not equipped with a termination switch.
When a Router is connected to the end of a channel,
the termination switch on the JB/T must be set to
terminate (TERM), as shown in Channel A of Figure
12-5.

Refer to Figure 12-2 for the Router connection
points.
 Do not route wires over hot, sharp,
or abrasive surfaces.

Logical Installation

NETWORK TOPOLOGY AND DATA MEDIA

After the Router is physically attached to the network, and powered up, it must be logically installed
using LonMaker. The logical installation is covered
in the LonMaker Installation Tool Users Guide.

Refer to section 2 for information on the network topology and data transmission media.
 AC voltages and currents present
an electrical shock hazard that can cause severe personal injury or death. Only qualified
personnel are to perform the following procedures.

When installing a network that contains a Router, the Router must be installed first.
This section provides an overview of the logical
installation of a Router.

Connections

A Router is a single device that contains two Neuron chips, one serving each channel. In a network
with one Router, Channel A can have up to 43 additional nodes and Channel B can have up to 43 additional nodes, for a maximum of 44 nodes per channel.

Network data connections are made at the RJ45
connectors marked Net 1 and Net 2 (shown in Figure 12-2, cables supplied with the Router are shown
in Figure 12-4.)

A network diagram is needed to determine the number of channels in the network and which nodes are
assigned to each channel.

NETWORK INSTALLATION
Sections 3 and 4 provide a detailed description of
the network installation process. Read Sections 1
and 2, before constructing the network. Sections 3
and 4 provide the following step-by-step installation
procedures:

The following is an outline of the steps needed to
Define and Install a Router.
1. Create/Select one Domain and define the
channels that the Router(s) will connect.

1. Setting up Network Installation Tools

2. Choose a Location and Define the Router(s)
using Device Setup. Use a unique name for
each Router, this name can only be used once
in the network. Set up both sides of the Router(s) as using priority.

 # $  3
Channel – A Channel is the physical communications media that connects the devices and the
properties of these media (such as transmission
speed). Most PowerCommand network installations will have only one channel (twisted-pair wiring and 78 KBaud transmission speed). In a large
network, there may be multiple channels and each
channel may or may not be of the same media
type. Channels are linked together using Routers.
Comma Separated Value (CSV) – A record layout
that separates data fields with a comma and usually surrounds character data with quotes.
PCW uses the CSV record format.
Configured/Unconfigured – The term configured,
as used in this manual, refers to a module that has
been logically installed with LonMaker Software.
A “network image” (address and binding information) is stored in the node. A module that has not
been logically installed with LonMaker is referred
to as being unconfigured. The service LED will
blink on an unconfigured module.
Connecting Devices – Connecting refers to the
process of assigning connections—linking an output variable of one device to an an input variable of
another device. This process is also called “binding.”
Customer Site Database/ “Site Directory” – A
database that is specific to a customer’s installed
network. It contains two subdirectories,
“DB_TYPE” and “DB_INST”. When the PCNET
utility is executed, this directory structure is set up.
“DB_TYPE” contains the information LonMaker
needs in order to know what each module is and
what it can do. Once LonMaker is run and a specific customer site is set up (devices and binding defined), this information is stored in the “DB_INST”
subdirectory.

Attaching – Term used in this manual to describe
connecting the PC, used for network installation
and service, to the PowerCommand Network via
the Installation Gateway.
Binding – The process of making the logical connections on the network (also called connecting).
This involves connecting network variable outputs
to network variable inputs using LonWorks software.
Binding – The process of making the logical connections on the network (also called connecting).
This involves connecting network variable outputs
to network variable inputs using LonWorks software.
Boolean – A logical system used to express one of
two states, such as on or off (yes or no, 1 or 0 etc.).
Bound – A network communication technique
whereby a node automatically receives a network
variable from a sender node whenever the sender
node sends it out. The sending is completely controlled by the sender node. The network variables
involved are said to be “bound.”
Bus – The main “backbone” of the network data
wire. It must start at one point and end at another.
Stubs off the main bus wire must not exceed ten
feet. The wire is said to be “daisy-chained” from
one node to the next. Without using a router, the
maximum bus length is 4600 feet (1402 m).
Controls Communications Module (CCM) – A
module for monitoring genset or transfer switch
parameters. It also provides some control capability. There are two kit versions: CCM-Genset that
can be used on gensets that do not have a PowerCommand Control, and CCM-ATS that can be
used to monitor and control transfer switches.
(Refer to the CCM-Genset or CCM-ATS sections
of this manual for application information.)

Redistribution or publication of this document,
by any means, is strictly prohibited.

A-1

Digital I/O Module (DIM) – A network module with
four discrete customer inputs, and sixteen 5A, 250
VAC Form-C dry contact outputs. The four customer inputs are available on the network to control other devices or to indicate status. The 16 relays are controlled by other devices on the network.

Genset Communications Module (GCM) – The
GCM provides a communications gateway between the PCC and the network. The GCM communicates with the PCC over a serial data link.
The GCM gets data from the PCC such as volts,
current, engine speed, oil temp, etc. and then
sends it out on the network if another network
node is bound to it or is requesting data. The GCM
also provides some direct local control and monitoring of the PCC. It monitors for “Not-In-Auto”,
and both High and Low Battery voltage (when the
PCC is asleep) then sends it out on the network if
another network node is bound to it or is requesting data.
Installation Gateway – The term used in this
manual to describe the special Gateway (refer to
Gateway) used only when installaing or servicing
a PowerCommand Network.
Junction Box/Terminator (JBT) – A device that
provides connection points for network power and
data wires. It also contains a network terminator
circuit for use at the end of a network.
Onan has created a junction box/terminator
potted assembly. The JBT is required to connect
an NGM to the network. The JBT provides a (required) terminator circuit for NGM nodes that are
located at an end of a network. The JBT can also
be used as a convenient device for wiring pass
thru, local loop and stub connections throughout a
network. It provides two 6-position pluggable terminal blocks for data and power, two RJ45 jacks
for temporary 24AWG stub connections (e.g.
NGM), a switch to connect the data lines to a terminator circuit and a switch to select either a pass
thru or a local loop connection between the data
lines on the terminal blocks.
Local Loop – A method of branching out to a node
that is farther away from the main network bus
than a stub would allow (i.e. >10 feet [3m]). It uses
two wire pairs — one pair to go out to the node,
and the other to return from the node. Effectively
the node is “daisy-chained” into the network bus.
The effective bus length for that particular run will
be twice the distance to that node. The total local
loop distance must be added into the maximum
network length of 4600 feet (1402 m).

Distributed Control System – A collection of
nodes that interact to control a system whose
components are spread out over some distance.
Each node has intelligence for operating its own
particular component of the system. Different
parts of the system communicate status and control information with one another to form a distributed control system. Typically they communicate
on a peer-to-peer level. This is different from a
type of system where all control and interaction
between components is dictated by one central
control (this type of system typically communicates in a master/slave arrangement).
A distributed control system can be more robust
than a central control type because failure of one
node will not shut down the whole system. The
other working nodes will still interact. If a central
control fails, the whole system shuts down.
Domain – A domain is a network concept that allows independently functioning networks to share
resources, such as transmission media. A domain
designation provides an ID number to identify the
devices that can communicate within that domain.
A network must have at least one domain. PowerCommand network installations will usually have
only one specified domain.
Gateway – A device that acts as interface between
two different communication protocols. The network gateway module (NGM) is an example that
translates PowerCommand network protocol into
a protocol that a PC can understand. Other gateway devices may translate between PowerCommand network protocol and other systems such as
SCADA, building automation systems, UNIX systems, etc.

A-2

Locations – Locations are subdivisions of a network that can be selected strictly for convenience
and organization. Locations may be used to designate physical places, but they do not have to do
so. For example, a “location” designator could refer to one row of devices, while another “location”
designator could refer to an adjacent row of devices on the same wall.

Multidrop Bus Topology – The wiring arrangement used for the network data. The bus that
starts at one point and ends at another. The topology allows “drops”(or stubs) off of the bus up to 10
feet (3 m) from the bus. One or more “Drops” can
be made any place along the bus (hence “multidrop”).
Network – A collection of Nodes that communicate
with one another over a distance. The PowerCommand network communication is implemented
transformer coupled twisted pair data wire. The
“language” that is “spoken” on the network is
called the protocol.

Network devices in one location can communicate
with network devices in another location. A network must have at least one location name. A device can be in only one location.

Network Annunciator Module (NAM) – An application which combines a hardwired PowerCommand System Annunciator with a Digital I/O
Module. This module is available in two versions:
one has an oversize cover for flush mounting and
the other has a smaller cover for surface mounting. The module is prewired for NFPA110 applications. The module can be modified for generic annunciation applications.

LonMaker Site Database – See Customer Site Database
Manchester Encoding – a method of representing
1’s and 0’s on a media which results in polarity insensitive wiring.
Master/Slave – A type of communication protocol
whereby one device controls all communication
on the channel. This is the master. The slaves are
all of the other devices. The slave devices talk only
when the master tells them they can. An example
of this is a computer and a printer. The printer is
the slave device. See Peer-to-Peer.

Network Data – A signal that carries messages between nodes. In this network, it is a Manchester
encoded digital signal. Manchester encoding
makes the signal insensitive to polarity (i.e. the
two data wires may be connected in either polarity). The signal is transformer-coupled to the network data wire at a rate of 78 k bits/sec. Transformer coupling into twisted pair wire gives excellent noise immunity. (It is far superior to either
RS-232 or RS-485 for example.) Shorting of the
wire pair will cause no permanent damage, but
communications will be affected. Opens prevent
nodes on each side of the open from communicating, but nodes on one side of the open will still
communicate. An unpowered node will not prevent other powered nodes from communicating.

Media – The hardware level of communications.
This defines two things: 1) what the electrical signal levels will be and 2) over what they will travel.
Examples of media are: RS-232, RS-485, transformer coupled twisted pair, radio frequency, fiber
optic, coax, infrared, and power line. Note that the
media does not define what “language” (protocol)
nodes will use to communicate information with
one another.
Modem – (MOdulator DEModulator) A device that
adapts a terminal or computer to a telephone line.
It converts the computer’s digital pulses into audio
frequencies (analog) for the telephone system
and converts the frequencies back into pulses at
the other side. The modem also dials the line, answers the call and controls transmission speed.
(The modem should be set to operate at 9600 bps
for use in a PowerCommand Network.)

Network Data Wire – Twisted pair communications
wire that carries the network data communication
signals. The wire must meet UL Level IV requirements (as listed in UL’s document: “UL’s LAN
Cable Certification Program”). Equally acceptable
is wire conforming to EIA/TIA Category 4 (as described in EIA/TIA Technical System Bulletin #36).
These requirements specify the transmission line
characteristics for the wire (attenuation, characteristic impedance, crosstalk, etc.). These characteristics are critical to maintaining a good signal.
22 AWG wire must be used for the network bus. 24
AWG may be used on stubs. The cable does not
need to be shielded. Maximum bus length is 4600
feet (1402 m). Redistribution or publication of this document,

nodes or devices) are the various hardware modules on the network, such as the Digital I/O Module, the Controls Communications Module, and

network are not hard-wired connections, they are
programmable software values.

Network Module Library – The Network Module
Library (NML) is a software database that describes devices, channels, and predefined input/
output connections. The NML is used by PCNET
to create the “Site Directory.”

Neuron Chip – A communIcations processor developed by Echelon Corporation for use in distributed control systems. The Neuron chip firmware
implements a sophisticated communications protocol, allowing nodes to communicate through the
passing of network variables. The Neuron chip
also has I/O to support modest application circuits.

Network Gateway Module (NGM) – A network device that acts as a gateway between a PC or modem and the network. The “site“ NGM allows software running on a PC to access, poll, and control
all devices on a network. The PowerCommand
Software uses this device to access the network.

Node – A module that can communicate over the
network data wire to other modules. A module
containing a Neuron chip.

The NGM connects to network data through an
RJ45 jack. Connecting to it requires a 24 AWG
cable. The NGM receives its power from AC utility
power.

Pass Thru – Refers to a junction box connection
where the network bus comes to a connector and
then continues straight on through. It is merely a
point for splicing wires. The Onan junction box/terminator provides this function.

Network Installation Gateway – A special NGM
that is configured for installing and servicing a network. Do not use the Network Gateway Module to
install or service a network or its configuration information will be lost. Always use the Network
Installation Gateway for installing and servicing
networks.

PCNET – A utility program that is used to create a
“customer site” or update an existing site with the

Network Power – B+ is used to power remote network devices such as the Digital I/O Module, Network Annunciator and Controls Communications
Module. For limited distances, this may be supplied by the genset battery. For greater distances,
an auxiliary battery will be needed to prevent module power loss during cranking.

Peer-to-Peer – A type of communication protocol
whereby any device on the communication channel can communicate with any other device at any
time. That is, no one device is the master of the
communication medium. The PowerCommand
Network is a peer-to-peer type network.

Network Power Wire – Wire used to run power to
nodes that do not have a local source of power
(e.g. Digital I/O Module, Network Annunciator
Module , etc.). The wire gauge must be chosen for
the number and type of nodes and the maximum
distance from the power source to a load node.
Refer to the Network Power section for data on
wire selection.

Polling – A network communication technique
whereby a node asks another node for its current
value of a network variable. The node doing the
asking forces the other node to send out that network variable.
Protocol – The protocol is a language that each
node on the network knows how to speak and interpret. It is not to be confused with communications media. The media is the hardware level of
the communications. The protocol is what allows
devices to exchange messages with one another.
A protocol can be very simple or very complex.
Echelon’s LonTalk Protocol, used in the Neuron
Chip, is very sophisticated.

Network Variable (NV) – Network Variables send a
value with defined units from one device (the output) to another (the input). Each network variable
is either an input or an output. Also see Connecting Devices.
Data that can be accessed or driven through the
network. Examples would be: Genset voltages,
genset start/stop, etc. Some NVs are used purely
for monitoring purposes. Others are used for control between devices.

RJ45 Connector – An 8-position phone jack connector. Some nodes (e.g., NGM) connect to the
network via an RJ45 connector. Network data is
brought in on positions 1 and 2 (the two left-most
positions as the plug is viewed from the contact
side (as opposed
to the side with the latch).

Twisted Pair Communications Cable – A cable
containing typically one, two or four twisted wire
pairs. The cable is specified according to its characteristic impedance, maximum operating frequency, attenuation, capacitance, and cross-talk.
These are all important parameters for reliable
data transmission.
Single pair cable will contain one white/blue and
one blue wire. This would only carry network data.
Two pair cable will contain one pair of white/blue &
blue and one pair of white/orange & orange. The
blue pair would carry network data. the orange
pair could be used in local loop configurations.
Four pair cable will contain paired colors of blue,
orange, green and brown. Again, blue is primary
for network data. Orange, Green and Brown can
be used for network data — may be used for a local loop.
The wire comes as either 22 AWG (for main bus or
stubs) or 24 AWG (for stubs only), plenum or PVC
insulation, and with or without a drain/shield. The
PowerCommand Network does not require the
use of shielded cable. Plenum vs. PVC insulation
will be chosen based on code requirements for fire
resistance. If network power is being run in the
cable, then the cable must be in conduit.
Uninterruptible Power Supply (UPS) – A backup
power supply used when the electrical power fails
or drops to an unacceptable level. Small UPS systems provide power to operate equipment for a
number of minutes. There are two main types of
UPS: an online UPS that provides a constant
source of electrical power from the battery and an
offline UPS, also known as a standby UPS, that
switches to battery power a few milliseconds after
detecting a power failure.
Onan has an optional standby UPS that can be
used to provide backup power for a modem and
network gateway module.

Router – A router is a device that connects one
channel to another. Routers are not required when
there is only one channel in a network.
A router can also be used to extend the PowerCommand Network bus or extend the number of
modules on the network.
Standby Uninterruptible Power Supply – See
Uninterruptible Power Supply
Stub – A branch off of the network bus. It must not
exceed 10 feet (3m).
Terminator – A circuit that is required at both ends
of the network bus. This circuit acts to optimize the
transmission line characteristics (minimizes signal reflections). It is critical that the network bus be
properly terminated. Without terminators or terminators in the wrong places, network communications can be severely hampered. Even if the network appears to be working, messages are likely
getting lost or unnecessarily repeated, increasing
network traffic. Noise immunity is also greatly reduced. Each network module except the NGM has
a terminator built in. On Onan-designed nodes, a
slide switch is used to connect the terminator circuit to the network data lines. Junction boxes also
contain built in terminators with a slide switch to
activate it. The terminator on the junction box
would only be used if an NGM was located at the
end of the network bus because the NGM has no
terminator circuit.
Topology – The physical wiring arrangement for
the network data communications. Example topologies are bus, ring (e.g. Token Ring), star and
mixed. The network data described in this document communicates on a multidrop bus topology.

MODEM

MULTI-SITE COMMUNICATIONS MODULE

The modem provides a dial in/out link to other communications sites. The modem is AC powered. The
modem communicates with the Network Gateway
Module that communicates at 38,400 bps (on the
serial (RS-232 side). The Onan Model PMDM 100
is the only approved modem for operation in the
PowerCommand Network as of this printing.

The Multi-Site Communications Module allows a
single computer running PowerCommand Software
to communicate with up to eight remote sites simultaneously. This module is installed in an ISA bus
compatible personal computer and it contains all of
the necessary RS-232 communications connections for use with external communications equipment. This module should only be installed by
someone familiar with computer servicing.

STANDBY UNINTERRUPTABLE
POWER SUPPLY (UPS)
Onan has an optional standby UPS that can be
used to provide backup AC power for the Network
Gateway Module and a modem. The UPS will provide backup power for a minimum of 30 minutes.
Use of a UPS will allow the modules (that are battery
powered) on the PowerCommand network to communicate a power failure to a remote location via the
NGM and modem during a power failure.
A multi-plug receptacle will be needed to connect
more than one device to the UPS.

network variables in other modules that are bound
to it, are automatically updated via the network.
Making these bound connections creates a network
where control signals and data are automatically
sent and received.

NETWORK VARIABLES
The PowerCommand network recognizes module
inputs and outputs as network variables (NVs) and
message tags. Both network variables and message tags perform the same basic functions, they
exchange values and information between modules. These inputs and outputs are not hard-wired
connections between the modules, they are software values.

When installing the PowerCommand network you
will need a diagram of all the logical connections.
The logical connection diagram should be prepared
before starting the installation to save time during
the installation. A list of the network variables that
can be connected are listed with each module in the
back of the section.

Network variables send a value with defined units
from one device (the output) to another (the input).
Each network variable is either an input or an output.

Network Variable Rules and Limits

Message tags are similar to network variables, but
they are used to send explicit messages. In the
PowerCommand network, message tags are only
used to send alarms to the PowerCommand software. The CCM and GCM have message tag outputs and the NGM has a message tag input.

Network variables and message tags are connected using the LonMaker Installation software
(refer to Section 3). Certain network variable rules
and limits must be followed when making these
connections. Refer to the following rules and limits
when designing or troubleshooting a logical binding
diagram.

Some network variables are of the analog data type
structure. These network variables are not connected or bound. Instead, these network variables
are made available to application programs (such
as PowerCommand Software for Windows), which
can then request the data from the source module
(GCM or CCM).

Data Type Matching: Connect only variables of the
same data type. The installation tool (LonMaker)
will not allow mismatched types to be connected.
For example, connect only Booleans to Booleans,
words to words, message tags to message tags,
etc.

BINDING NETWORK VARIABLES

Connections Within One Node: It is acceptable to
connect one network variable output to one network
variable input on the same module. The result will
function as expected, but the network update will
not appear on the network media, instead it will remain within the module.

Logically connecting network variables between
modules is referred to as binding. Connecting the
network variables results in a bound connection.
The result of a bound connection is that when a
module updates an output network variable, input

More Than One NV Input Controlling the Same
Device: The Digital I/O Module has two means of
controlling the relays. There are the individual Boolean inputs, nviRelay[x], and there is the 16–bit
word, nviAllRelays. If both are used, the result will
be that the inputs are logically or’ed within the module.

Making Connections Other Than One Output to
One Input: Making connections other than one-toone is allowed, but it must be clearly understood
how the resulting system will behave. The other
scenarios are: 1) multiple outputs connected to one
input; 2) One output connected to multiple inputs;
and 3) multiple outputs connected to multiple inputs. These are discussed in more detail below.

For example:

Multiple Boolean Outputs: When multiple Boolean outputs are involved in one connection, it is
necessary to understand how the connected Boolean input(s) will respond to updates. Some node
types implement an equivalent hardwired OR’ing
scheme while others do not. Refer to the following
section called Multiple Outputs to One Input for a
description of the possible results.

If both nviRelay[1] and bit 0 in nviAllRelays (bit
which controls Relay1) start out both as “0” (relay in
reset state). If nviRelay[1] is updated to “1”, the
relay will be set. If bit 0 of nviAllRelays then is updated to “1”, the relay will remain in the set state.
Now, if nviRelay[1] is set to “0”, the relay will still remain set until bit 0 of nviAllRelays is set to “0”.

Address Table Consumption: Bindings consume
memory in each module. There is a limited amount
of memory for storing the binding information. It is
stored in a place called the “address table”. The
installation tool (LonMaker) acts to optimize the addressing so that minimal address table space is
consumed. However, in certain situations, all address table entries will be consumed. LonMaker will
inform the user when this occurs.

by creating a test site and then make the connections using LonMaker. LonMaker will inform the
user if the limits are exceeded.

Due to the complexity of the addressing schemes
that the protocol uses, it would be difficult to create
simple rules to determine whether the address table
limit was going to be exceeded for a particular system binding design. In general, the greater the
number of connections, the more address table
space consumed. Address table consumption is increased when connections are made between
many different NV’s on one device to single NV’s on
many different modules. If in doubt about whether a
particular application will exceed the limits, try it out

Only 5 of the 7 connections listed could be made
due to the address table limit. This is a worst case
example. In this case, add another DIM to the network.

The most severely limited device in terms of address table entries is the Digital I/O Module. It has
only 5 address table slots, whereas the CCM and
GCM module types have 15.
An example of a situation that would NOT WORK
with the DIM or NAM is shown in Table C-1.

Having only 5 address table entries on the DIM
DOES NOT mean that there can be no more than
5 connections. This example illustrates a particular situation where this can occur. If connection
numbers 6 and 7 had both come from GCM1, then
all connections could be made.

FIGURE C-2. ONE OUTPUT TO ONE INPUT BINDING DIAGRAM

TYPES OF CONNECTIONS

One Output to One Input

The different types of connections are explained in
the following sections. It is important to consider the
type of connections being designed or made and
how the results of these connections will affect other
devices. The logic involved may not behave in an
intuitive or familiar manner.

This is the most straightforward type of connection.
The only requirement is that the data types must
match. When the output is sent on the network, the
input will automatically get it and take appropriate
action.

puts say they are a “0”, the input is set to “0” and appropriate I/O action is taken.

Multiple Outputs to One Input

The DIM’s Boolean inputs do not implement a
“wired OR” function. Therefore, if multiple outputs are connected to a Boolean input, the input will
be in whatever state it received from the most recent update. If one output tells it to be “1” and another afterwards tells it to be a “0”, it will be a “0”. This is
“standard functionality” behavior as described in
the next section.

Multiple outputs from one module cannot be connected to one input on a single module.
Some of the Boolean network variable inputs on the
CCM and on the GCM implement a “wired OR”
functionality. All of the Boolean inputs shown in
Table C-2 implement this functionality. When multiple Boolean outputs from other modules are connected to one Boolean input, that Boolean input will
remain a “1” until all of the connected Boolean outputs are “0”. The modules implement this by polling
all connected outputs each time a “0” is received
from one of them. If, as a result of the poll, all out-

Standard Functionality: For all network variable
inputs except the Boolean inputs on the CCM and
GCM listed in Table C-2, when multiple outputs are
connected to one input, the input will contain the

same output from DIM1 is sent to two inputs on the

When the one output is sent out on the network, all

once (i.e. it is not sent out once for each input).

FIGURE C-5. TYPICAL MESSAGE TAG CONNECTIONS

Table C-4 shows a typical message tag output and
input for a dial out connection.

Message Tag Connections
Message tag connections are a special class of
connections. In the PowerCommand Network, the
only purpose they serve is as the link for alarms to
be sent to PowerCommand Software through either
a local or a remote connection. The CCM and GCM
have message tag outputs. The NGM has a message tag input. In order for alarm notification to
work, the tags must be connected using the LonMaker installation tool.

 DO NOT connect message Tag outputs to more than one input. It is OK to connect
multiple message tag outputs to one message
input. The result of this restriction is that alarm
notification from a module can only go out
through ONE Network Gateway.

INTRODUCTION
This section provides a troubleshooting information
to help diagnose PowerCommand Network problems. Refer the Error Message and Troubleshooting Section, in the LonMaker Users Guide, for problems with LonMaker that are not covered here.

Refer to specific module sections to review the LED
indicator location and descriptions. The SERVICE
and STATUS indicator LEDs can be used as a visual aid in diagnosing problems.

The PowerCommand Network can be used to remotely operate power transfer equipment (e.g.,
transfer switches, paralleling systems) and start
and stop generator sets. All of the safety precautions for that equipment must observed. Refer to the
Operator’s Manual for the equipment that is being
monitored and controlled by the network for important safety precautions. Review the Safety Precautions listed in the front of this manual for important
safety information.

Use the following troubleshooting Tables to help
diagnose PowerCommand Network problems. The
troubleshooting Tables are divided into sections
based on the symptom. Common problems are
listed with their possible causes. Refer to the corrective action column for the appropriate procedure.


Power equipment presents a shock
hazard that can cause severe personal injury or
death. The PowerCommand Network allows remote operation of equipment. PowerCommand
Software for Windows can remotely start and
stop a genset or exercise a transfer switch. Network modules can independently control other
network modules and operate other electrical
devices such as fans or pumps etc. Make certain that all appropriate personnel are notified
before remotely operating equipment and make
them aware of any equipment that can be energized automatically.

Most network problems are related to poor or improper wiring connections. Make a through inspection of the network wiring to make sure that good
connections are made and the modules are wired
correctly. Correct all wiring problems before proceeding with troubleshooting.
Refer to the Additional Installation Steps near the
end of Section 4. Make sure each of the modules
have been reset after using PCT for configuring the
network or making changes. Also make sure the

TABLE D-1. PCNET PROBLEMS/ERROR CODES

PROBLEM “MESSAGE”

CORRECTIVE ACTION

1. “Bad command or file name”

1a. Make sure you are in the Onan directory.
1b. Make sure PCNET is in the \ONAN directory
1c. Make sure the Network Module Library installed without errors.

2. “Unable to create directory
‘[site_path]’.”

2a. PCNET is only able to create a sub-directory one level below an
existing directory.
(If ‘C:\ONAN\SITES’ is an existing path without a sub-directory
called ‘NEW_SITE’, then PCNET would be able to create a new
site at ‘C:\ONAN\SITES\NEW_SITE’ but not at
‘C:\ONAN\SITES\NEW_SITE\TEST’. The path
‘C:\ONAN\SITES\NEW_SITE’ must already exist to create the
sub-directory ‘TEST’.)

– OR –
“LonMaker requires at least
xxK bytes of additional free
memory to operate.”

1a. Not enough conventional or lower memory. LonMaker requires
about 582K of conventional memory. Free up memory by:
1b. Loading drivers in upper memory: “DEVICEHIGH=C:\... ”
(Note: NOT ALL drivers can be loaded high.)
1c. Loading gateway driver in upper memory:
“DEVICEHIGH=C:\ONAN\BIN\LDVSLTA.SYS /M /B9600 /P1”
1d. Running DOS command MEMMAKER to optimize memory usage.
1e. Create an alternate boot up configuration to load only drivers
needed to run DOS and LonMaker.
1f. (Contact a PC service center for assistance if required.)

2. “Error opening database.”
(This comes after the Lon
Maker Introductory screen
and the “Initializing...”
screen.)

2a. The site path is more than 26 characters (including characters for
drive “C:” and backslashes “\”).
Move site directory to a location with a path less than 26
characters. (e.g. If the site directory is located at
“C:\ONAN\SITES\MINN\FRIDLEY\SITE_12” you would get this
error message since the path is 34 characters. Moving the
directory to “C:\ONAN\SITES\MN\SITE_12” would work.
2b. If LonMaker ended abruptly the last time you ran it for this site,
the LonMaker database may be corrupt. Try running “PCNET...”
again to the problem site directory and run LonMaker again. If
LonMaker still will not run, you’ll have to:
Delete the directory where the site database is located and
re-run “PCNET...” and define and install all the modules again.

File Directory

COM Port Connection Problems

When the Network Module Library and the PowerCommand Configuration Tool software are installed
on the installation PC, the file directory structure
should appear as shown in Figure D-1.

Check the COM port connection. Verify that the
cable is attached to the correct COM port as specified when the driver was loaded in the config.sys file
(/p1, /p2, etc.). IF PCW is setup to use the same
COM port as PCT, make sure that PCW is not operating before attaching to the site with PCT.
A connection problem can occur with some computers when exiting PCT in Windows 95 to run LonMaker. If LonMaker will not attach to the site, Windows 95 may not be releasing the port.

If this occurs, the port will need to be disabled and
re-enabled. Use Device Manager, located in the
System folder of Control Panel, in Windows 95. Under Ports, select the COM port that the NGM is attached to and select Properties. Under Device
Usage, unselect the check box to disable the port,
then click OK. Repeat this procedure and click on
the check box to select it and enable the COM port,
then click OK.
