Overview of Ports
Introduction Each Processor Adapter is equipped with at least one Modbus or Ethernet port.
Some models also have a second port. The ports allow the Processor Adapter to
communicate with:
lProgramming panels
lNetwork I/O points under its control
lNetwork supervisory computers
Ports Per
Processor
Adapter
The following table indicates which ports are available with each Processor
Adapter:
Ethernet Port The Ethernet port is a standard, twisted pair, Ethernet 10BASE-T port which can
communicate with programming panels, other M1 Processor Adapters with
Ethernet ports, and with other Ethernet products. This port has an RJ45 connector,
with an industry standard pinout.
Modbus Port 1 Modbus Port 1 is a general-purpose asynchronous serial port with dedicated
RS232 slave functionality. This port has an RJ45 connector.

Memory and Performance Characteristics
Introduction Processor Adapters are equipped with internal memory and Flash RAM. This
section explains those two types of memory and describes the memory size and
performance characteristics of each Processor Adapter.
Internal Memory Internal memory includes user memory and state RAM:
lUser memory contains the control logic program and such system overhead as
the Processor Adapter configuration, I/O mapping, checksum and system
diagnostics.
lState RAM is the area in memory where all the input and output references for
program and control operations are defined and returned.
The user may change the way internal memory is allocated by adjusting
parameters for user memory and state RAM.
Flash RAM Flash RAM contains the executive firmware, which is the operating system for the
PLC. It also contains a firmware kernel, which cannot be changed. The kernel is a
small portion of memory that recognizes acceptable executive firmware packages
and allows them to be downloaded to the Processor Adapter.
Space is also provided in Flash so that a copy of the user program and state RAM
values can be stored. This back-up capability is particularly useful in configurations
where no battery is used (i.e., a Processor Adapter without an Option Adapter).
When the module is successfully communicating with other devices, if a ring
adapter with battery back up is not present, it is recommended that you stop the
processor and save the user program to Flash. This will save the processor’s ARP
cache and enable it to “remember” this information if power is lost or removed.
This procedure should also be followed whenever:
lA new or substitute device is installed on the network;
lThe IP address of a network device has been changed.

Scantime
Formula for
984LL Exec
The following formula applies to the M1E Processor Adapter with the 984LL exec.
Scan time = (0.25 msec/ethernet device + 0.002 msec/word) + 0.13 msec/K of
logic + 0.40 msec + MBPlustime
Example You have 50 ENT modules connected to a single M1E with a configured time of 50
Msec each, a total of 4k user logic and no MB+ card. The scan time for all modules
configured as fast as possible would be 12.5 Msec + 0.52 Msec + 0.40 Msec =
13.42 Msec. However, since the M1E will only communicate to 1/4 of the modules
(12.5 Msec/50 Msec = 1/4) on any given scan, the corrected average scan time
would be 1/4 x (12.5) + 0.52 + 0.40 ≅ 4.1 Msec.

Safety Parameters
Degree of protection Unintentional access (UL 508 Type 1, NEMA250 Type 1,

Di-electric strength Ethernet is isolated from logic common 500 VDC
Ground continuity 30 A test on the exposed metal connector
Agency Approvals UL 508, CSA, CUL, CE
FM class1, div2
Note:
Modbus Plus communications will slow the M1E. If there is no MB+ ring card then
MBPlustime = 0.
If there is a MB+ ring card, then each scan will be extended 0.3 Msec
even if there is no
message
.
Modbus Messages will add from 1 to 2 msec per scan, depending on the length of the
message.
Note:
The formula above presumes that all MSTR blocks and all configured connections are
set to go as fast as possible. In this case the M1E will attempt to exchange data with
each device once per scan.
If several devices are configured to communicate on a timed basis that is substantially
larger than the scan time calculated, then the communications to those devices will be
spread out over several scans. See Example, below.

LED Indicator This Option Adapter has one LED indicator, the Com Act indicator. Its functions are
described in the table below.
Modbus Port 2 Modbus Port 2 is a general-purpose asynchronous serial port with user-selectable
RS232/RS485 slave functionality. The choice between RS232 and RS485 is made
in the software.
Auto-Logout
Feature On
Modbus Port 2
If the RS232 port is chosen, auto-logout is supported. If a programming panel is
logged into the CPU via the serial port and its cable gets disconnected, the
Processor Adapter automatically logs out the port. This auto-logout feature is
designed to prevent a lock-up situation that could prevent other host stations from
logging in on other ports.
Auto-logout is not available for any RS485 port, including the RS485 option on the
Serial Option Adapter. The user must log out of the processor using the
programming software.

flashes the following patterns, based on the status of the Modbus Plus node:
Continued on next page
Pattern Meaning
6 flashes/s This is the normal operating state for the node. It is receiving
and passing the network token. All nodes on a healthy
network flash this pattern.
1 flash/s The node is offline just after power-up or after exiting the
6 flashes/s mode. In this state, the node monitors the
network and builds a table of active nodes. After being in
this state for 5s, the node attempts to go to its normal
operating state, indicated by 6 flashes/s.
2 flashes, then OFF for 2s The node detects the token being passed among the other
nodes, but never receives the token. Check the network for
an open circuit or defective termination.
3 flashes, then OFF for 1.7s The node is not detecting any tokens being passed among
the other nodes. It periodically claims the token but cannot
find another node to which to pass it. Check the network for
an open circuit or defective termination.
4 flashes, then OFF for 1.4s The node has detected a valid message from a node using a
network address identical to its own address. The node
remains in this state for as long as it continues to detect the
duplicate address. If the duplicate address is not detected
for 5s, the node changes to its 1 flash/s mode.
ON Indicates an invalid node address.
OFF Possible fault with Modbus Plus Option Adapter.

Installing Batteries in an Option Adapter
Installation Guidelines
Why Install
Batteries? If you are using a Momentum Option Adapter in your CPU assembly, you have a
battery-backup capability. The batteries will maintain user logic, state RAM values
and the time-of-day clock in the event that the CPU loses power.
What Kind of
Batteries? Two AAA alkaline batteries can be installed in the compartment on the side of the
Option Adapter. A set of batteries is supplied with the module (not installed).
Installing
Batteries When installing the batteries, observe correct polarity, as indicated on the
compartment door.

Installation Guidelines, Continued
Leave Power On
When Changing
Batteries
Once your CPU has been commissioned and is running, maintain power to the
module whenever you change the batteries.
Unless you save to flash, if you change the batteries while the power is OFF, you
will have to reload your user logic program from the original files.
Removing and
Replacing
Batteries
Battery maintenance should be performed only by qualified personnel according to
the following illustration.
Monitor the
Battery Because a Momentum CPU assembly is designed to be installed in a cabinet
where it cannot be seen at all times, no LED was created to monitor battery health.
We recommend that you reserve a battery coil in your programming panel software
configuration and use it to monitor the health of your battery and report the need for
replacement prior to battery failure (refer to
Reserving and Monitoring a Battery
Coil

Cable Accessories for Modbus Port 1
Overview This section describes the cable and D-shell adapters needed to connect Modbus
Port 1 to a programming station. It also provides pinouts for the adapters.
Cables The cable connecting a programming station to the CPU (via Modbus Port 1) can
be up to 9.5m long. Three premade cable assemblies are available from Schneider
Electric:
All three assemblies are standard eight-position, foil-shielded, flat telephone cables
with male RJ45 connectors on each end. One RJ45 connector plugs into Modbus
Port 1 on the CPU, and the other plugs into a female D-shell adapter that fits onto
the programming station.
D-Shell Adapters Two D-shell adapters are available from Schneider Automation for CPU-to-
computer connections:
lA 110 XCA 203 00 9-pin adapter for 9 pin serial ports
lA 110 XCA 204 00 25-pin adapter for 25 pin serial ports
These adapters have an RJ45 jack on one end that allows them to clip directly onto
a cable assembly.

Two Types of
Port Modbus Port 2 is available in two types:
Features of an
RS485 Port Modbus Port 2 can be configured as an RS485 port. RS485 supports two-wire or
four-wire cabling. A multimaster/slave system must use two-wire cabling. A single
master/slave system may use two- or four-wire cabling.
The RS485 protocol handles messaging over long distances with higher level of
noise immunity than RS232 without the need for modems.
Limit of Two
Modbus Ports The Momentum M1 Processor Adapters can support a maximum of two Modbus
ports.
If a 172JNN 210 32 Serial Option Adapter is used in conjunction with a
171 CCS 780 00 or 171 CCC 780 10 Processor Adapter, the RS485 port on the
Processor Adapter becomes Modbus Port 2. The port on the Option Adapter
becomes electrically neutral and does not support any communication activities.
(The TOD clock and battery backup system on the Option Adapter continue to
work.)

If the Serial Option Adapter is used and the RS232 port is chosen, auto-logout is
supported. If a programming panel is logged into the CPU via the serial port and its
cable gets disconnected, the Processor Adapter automatically logs out the port.
This auto-logout feature is designed to prevent a lock-up situation that could
prevent other host stations from logging in on other ports.
Auto-logout is not available for any RS485 port, including the RS485 option on the
Serial Option Adapter. The user must log out of the processor using the
programming software.
Note: Processor Adapters support only one stop bit. If you change this default
setting in the configuration software, the Processor Adapter will ignore the
change.
Note: The default protocol must be changed from RS232 to RS485 for the
171 CCS 780 00,171 CCC 780 10 Processor Adapters or the port will not

Four-Wire Cabling Schemes for Modbus RS485 Networks
Introduction Four-wire cabling schemes may be used for single master/slave communications.
Only one master is allowed. The master may be located anywhere in the network.
Length The maximum length of cable from one end of network to other is 2000 ft. (609 m).
Number of
Devices The maximum number of devices in a network is 64 if all are Momentum devices.
Otherwise, the maximum is 32.
Termination You must terminate both ends of the cable run with special terminating resistors.
Master Cable The master of this master/slave cabling scheme must be connected on at least one
side to a master cable, a special cable that crosses the transmit and receive lines.
The other side may be connected to a master cable, or, if the master is at one end
of the cable run, a terminating resistor.

Ethernet Port
Introduction The Ethernet port allows a Processor Adapter to connect to an Ethernet network
for:
lhigh-speed I/O servicing
lhigh-speed data transfer
lprogramming
lworldwide connectivity via the Internet
linterfaces with a wide array of standard Modbus over TCP/IP Ethernet-aware
devices
Connector Type The Ethernet connector is a female RJ45 style phone jack.
Illustration The following illustration shows the position of the Ethernet port on a Processor
Adapter:
CAUTION
Communication Errors May Result
After taking an Ethernet Processor out of service, it is recommended that you clear the
program and IP address to prevent future conflicts.
Before installing a replacement Ethernet Processor on your network, verify that it contains
the correct IP address and program for your application.
Failure to observe this precaution can result in injury or equipment damage.
Using the Ethernet Port
870 USE 101 10 V..2 144
Network Design Considerations
Introduction In a distributed control environment, Ethernet can be used as:
lan I/O network
la supervisory network
la network that combines I/O and supervisory functions
This section discusses how to design your network to make communication
between related devices as effective and deterministic as possible.
When installed on a new network, the M1 Ethernet Processor will obtain the MAC
and IP addresses of other devices on the network. This process may require
several minutes.
When the module is successfully communicating with these devices, if a ring
adapter with battery back up is not present, it is recommended that you stop the
processor and save the user program to flash. This will save the processor’s ARP
cache and enable it to “remember” this information if power is lost or removed. If
you do not save to flash the processor must repeat acquiring the ARP cache
information from the network.
This procedure should also be followed whenever:
lA new or substitute device is installed on the network;
lThe IP address of a network device has been changed.
Continued on next page
Note: Preserve your ARP cache information.
CAUTION
CONTROL NETWORKS MUST BE ISOLATED FROM MIS DATA NETWORKS
To maintain a deterministic Ethernet network, you must isolate Momentum Processor
Adapters and related devices from MIS data networks. Traffic from MIS data networks can
interrupt communication between control devices, causing your control application to
behave unpredictably.
Additionally, the high message rates that may be generated between M1 Processors and
I/O Adapters may bog down an MIS network, causing loss of productivity.
Failure to observe this precaution can result in injury or equipment damage.
Using the Ethernet Port
870 USE 101 10 V..2 145
Network Design Considerations, Continued
I/O Networks In an Ethernet I/O network architecture, an M1 Processor Adapter is used to control
Momentum I/O points equipped with an Ethernet Communication Adapter or other
Modbus over TCP/IP Ethernet-aware devices. Communication between these
devices should be isolated not only from MIS data traffic, but also from unrelated
communication between other control devices.
You may isolate communication by creating a separate network or by using
switches.
Supervisory
Networks In a supervisory architecture, several intelligent processing devices share system
data with each other. Many kinds of devices may be part of the network. You should
be aware of each device’s requirement for access to the network and of the impact
each device will have on the timing of your network communication.
Combined
Supervisory and
I/O Handling
If your system requires both supervisory and I/O handling architectures, one
solution is to use the I/OBus capabilities of the 171 CCC 960 20 Processor Adapter
for the I/O network and the Ethernet capabilities for the supervisory network.
If you intend to use Ethernet to handle both functions, use switches to isolate the
network traffic and supply additional buffering of network packets.
Concurrent
Communication A maximum of 96 devices may be communicating with the Processor Adapter via
the Ethernet at any one time. This 96-device limit consists of:
lup to 2 programming panels (one must be in monitor mode)
lup to 14 general purpose Modbus server paths
lup to 16 MSTR elements which support Modbus read, write or read/write
commands
lup to 64 cyclic configured data slave paths

Security
Overview To restrict access to your Ethernet controller and I/O network, you may want to
consider a firewall. A firewall is a gateway that controls access to your network.
Types of
Firewalls There are two types of firewalls:
lNetwork-level firewalls
lApplication-level firewalls
Network-Level
Firewalls Network-level firewalls are frequently installed between the Internet and a single
point of entry to an internal, protected network.
Application-
Level Firewalls An application-level firewall acts on behalf of an application. It intercepts all traffic
destined for that application and decides whether to forward that traffic to the

Cabling Schemes
Introduction In a standard Ethernet cabling scheme, each device connects via a cable to a port
on a central Ethernet hub.
Length The maximum length of cable between devices depends on the type of hub used,
as shown in the following table:
Cabling with
Traditional Hubs The following illustration shows the maximum number of hubs and the maximum
cable length between devices when using traditional (non-switching) hubs:

Assigning Ethernet Address Parameters
Overview As shipped from the factory, the M1 Ethernet Processor does not contain an IP
address. This is also true if you have not programmed the unit with an Ethernet
configuration extension. In this condition, when the module starts up, it will attempt
to obtain an IP address from the network’s BOOTP server.
You can use Concept to assign an IP address, default gateway and sub network
mask. See
Setting Ethernet Address Parameters
on page 348.
You can also assign IP address parameters using the BOOTP Lite software utility.
See
Using BOOTP Lite to Assign Address Parameters
on page 152.
Using a BOOTP
Server A BOOTP server is a program that manages the IP addresses assigned to devices
on the network. Your system administrator can confirm whether a BOOTP server
exists on your network and can help you use the server to maintain the adapter’s IP
address.
How an
unconfigured
(“as shipped”)
module obtains
an IP address
On startup, an unconfigured processor will attempt to obtain an IP address by
issuing BOOTP requests. When a response from a BOOTP server is obtained, that
IP address will be used. If a response is not heard, then the Bootp requests will
continue for as long as the unit remains powered or until a response is heard.
Specifying
Address
Parameters
Consult your system administrator to obtain a valid IP address and appropriate
gateway and subnet mask, if required. Then follow the instructions in
Setting
Ethernet Address Parameters
on page 348.
Continued on next page
CAUTION
DUPLICATE ADDRESS HAZARD
Be sure that your Processor Adapter will receive a unique IP address. Having two or more
devices with the same IP address can cause unpredictable operation of your network.
Failure to observe this precaution can result in injury or equipment damage.

When the
Processor
Adapter is
Powered-up with
a Configuration
for “Use Bootp
Server”
If the processor adapter is powered up without battery backup, and its IP address
was previously saved to flash, the adapter will issue three Bootp requests five
seconds apart.
lIf a Bootp response is received from the server, the IP address will be assigned
but will not be saved to flash. Use the programming software to save the IP
address to flash. If a power cycle occurs on the processor adapter, the IP
address that is currently saved in flash will be used.
lIf a Bootp response is not received from the server, the processor adapter will
use the IP address that is stored in flash. Three ARP broadcasts are made, five
seconds apart, to check for duplicate IP addresses. Then, three gratuitous
ARP broadcasts are made two seconds apart with the station’s MAC address
and IP address.

When the

Adapter is

Configuration for

Address”
If the processor adapter is powered-up without battery backup and its IP address
was previously saved to flash; the adapter will listen for any Bootp messages but
will not will not issue any Bootp requests. Instead it will use the IP address that is
specified in the configuration. Then, three ARP broadcasts are made, five seconds
apart, to check for duplicate a IP address. Then, three gratuitous ARP broadcasts
are made, two seconds apart, with the station’s MAC address and IP address.
To Retain the IP
Address After setting the module’s IP address, you must save it to flash memory if you want
this setting to be retained when power is removed from the module. This is
necessary even if the module is attached to a ring adapter that provides battery
back up. See
Saving to Flash with Concept
on page 399.

Using BOOTP Lite to Assign Address Parameters
Specifying
Addresses/
Stopping the
Processor
Instead of a BOOTP server, Schneider Electric’s BOOTP Lite utility software can be
used to provide the IP address, subnet mask and default gateway to the processor.
A response from BOOTP Lite will cause the processor to enter Stopped mode on
completion of power up, if the processor has been set to “Specify IP Address”
mode via Concept. This is useful when inappropriate outbound network traffic might
result if the processor immediately transitioned into Run mode after power up.
Refer to the BOOTP Lite user documentation for instructions.
CAUTION
INCORRECT MAC ADDRESS HAZARD
Be sure to verify the MAC address of the target device before invoking BOOTP Lite. If you
do not enter the correct parameters of the target controller, it will run in its old configuration.
An incorrect MAC address may also result in an unwanted change to another device and
cause unexpected results.
Failure to observe this precaution can result in injury or equipment damage.
Note: BOOTP Lite and the user document are available for download at
www.modicon.com.

This field contains the number of consecutive collisions that occurred before the
frame was successfully transmitted out onto the Ethernet. Most transmitted frames
have zero collisions. Some have one collision on the first transmit attempt and
succeed on the second attempt. Some have more than one collision followed by
success. The largest number of consecutive collisions, since clear statistics
command, is stored and displayed in this field.
Receiver Errors
Words 18, 19
Framing Errors Counts the number of received frames addressed to this node that are greater than
320 bytes in length. Any such large frame has no relevance to the M1 Ethernet
adapter and therefore is skipped.
This error should not occur.
Overflow Errors Increments whenever a received frame cannot be copied into the frame buffer,
because the frame buffer is full. This situation should never occur under legal
Ethernet traffic.
Words 20, 21
CRC Errors Increments when the received packet is received under any of the following error
conditions:
lCRC error
lExtra data error
lRunt error
This counter can be made to increment by continuously disconnecting and
reconnecting the M1 Ethernet cable during cyclic communication.

Receive Buffer
Errors
Increments whenever a client attempts to connect to the M1 Ethernet, and fails,
because there is no available server path. The M1 Ethernet supports 14
simultaneous data paths and 2 program paths before this counter can increment.
This error indicates poor application architecture.
Transmission Errors
Words 26, 27
Transmit Buffer
Errors
Increments when the M1 is unable to transmit an Ethernet response frame because
all frame buffers are in use. For example, the M1 has 16 PING reply buffers. If all
16 PING buffers contain PING replies, ready to be transmitted, but this station’s
transmission is delayed because of collisions and backoff, and one more PING
request is received, then the new PING request is discarded and the counter is
incremented. This error can occur for PING, ARP, and connection attempt to server
path. Although this error is theoretically possible, it is not usually encountered.
Words 28, 29 Silo
Underflow This field counts M1 TCP/IP retries. All M1 clients and server use the TCP/IP
protocol which implements sequence numbers and timeouts. Whenever TCP/IP
data is pushed from the M1, a subsequent acknowledgement of receipt of M1 data
must be received within the timeout period, or else the M1 issues a retry. Retries
may be the result of any of the following conditions:
lThe original M1 data frame was garbled, corrupted, and lost
lThe target TCP/IP stack is operating more slowly than the M1 retry rate
For Modbus 502 servers, the M1 initiates retries after (1, 1, 2, 2, 4, 8) seconds.
For Modbus 502 clients, the M1 retry rate is the larger of:
l1/4 the health timeout for Ethernet I/O Scanner data (see
Accessing the
Ethernet / I/O Scanner Screen
on page 345,
OR:
l4 times the previous measured TCP/IP round trip time for i/o Scanner MSTR
block.

Late Collision Increments when the transmit frame process is aborted because of late collision
detected after the first 64 bytes of the frame was transmitted collision free. This
error could possibly occur if the Ethernet cable is intermittently connected and
disconnected.
Words 32, 33
Lost Carrier Increments whenever the Ethernet cable, connected to the M1, is disconnected
from the hub. Also increments whenever the Ethernet cable, connected to the hub,
is disconnected from the M1.

How I/OBus Works
Introduction This section describes how signals are passed and how data is transferred in an
I/OBus network.
How Signals Are
Passed I/OBus operates as a logical ring, with signals being passed by the master over a
remote bus cable to each slave device in series. The slaves return signals to the
master over the same cable.
How Data is
Transferred The I/OBus functions as a logical shift register. The application’s entire data stream,
originating at the master, is transferred serially from slave to slave down the remote
bus. Each slave regenerates the entire stream before passing it on. As a slave
handles the stream data, it extracts the portion that is assigned to it and adds any
output data to the stream.
Transmission
Speed Data is transmitted at 500 kbits/s.
Amount of data The number of 16 bit words in the data stream is dependent on the processor
model:
Model Max Input Words Max Output Words
171 CCS 760 00 128 128
171 CCC 760 10 256 256
171 CCC 960 20 256 256
171 CCC 960 30 256 256
Note: Processors that support IEC are limited to a maximum number of 1408
used I/O points, regardless of the number of modules.

Network Status Indication in the M1 Ethernet Module
Overview The M1 Ethernet Module can provide I/OBus network status via the Module Status
function in the programming panel or by a STAT element in user logic. The fourth
word of the status element contains information regarding the integrity of the
network.
Operation The I/OBus status word contains a valid value only when the processor is running.
A zero value indicates that normal I/OBus communication is occurring.
A non-zero value indicates a problem.
Failure
Indication If there is a communications error, bit values in the I/OBus status word contain
information on the failure mode, as follows:
BITS 0 - 14 These bits contain a value from 1 to 255, signifying the network position of the
module that cannot be reached. For example, a value of 8 indicates a
communications failure in accessing the 8th module on the network.
BIT 15 This bit contains a value of 0 or 1.
A value of zero indicates a general communication failure, for example, no power to
the module or a break in its input cable.
A value of 1 indicates that communication is possible, but the I/OBus ID received
from the module does not match the module type contained in the traffic cop for
that position.

Guidelines for I/OBus Networks
Overview This section gives guidelines for creating an I/OBus network using a Momentum
CPU as bus master.
Length The maximum distance between the Momentum CPU master and the farthest slave
is 13 km (8 mi).
Distance
Between Nodes The maximum distance between nodes is 400 m (1300 ft.).
Number of
Devices A network may consist of as many as 256 nodes, including one Momentum CPU
bus master and up to 255 slave I/O devices.
Acceptable Slave
Devices An I/OBus slave device can be:
lA Momentum I/O base with a 170 INT 110 00 Interbus Communication Adapter
mounted on it
lA Modicon Terminal Block I/O module enabled for Interbus communications
lA standard Interbus module designed by a third party manufacturer
Unacceptable
Slave Devices The I/OBus network does not support Interbus-compatible devices that require the
Interbus PCP protocol.

lA 1m cable with high profile rear shell
lA connector kit for building custom-length Interbus cables
This section describes those solutions.
Low Profile
Cables For side-by-side mounting of the CPU with Interbus I/O modules on a DIN rail or
wall, Modicon provides two specially molded low profile cables.
These cables have a male 9-in D-shell connector on one end and a female 9-pin D-
shell on the other. The male connector plugs into the female I/OBus port on the
Processor Adapter, and the female connector plugs into the male connector on the
left side of a 170 INT 110 00 Interbus Communications Adapter on an I/O base.
Additional cables can then be used to connect a series of I/O modules via their
Interbus communication ports.

Modbus Plus Features for Momentum
Introduction When a Modbus Plus network is constructed entirely of Momentum components, it
may take advantage of two new features:
lcluster mode, which allows small groups of devices to be linked by short
lengths of cable;
lsupporting up to 64 nodes on a
single
section of cable.
Cluster Mode A cluster may consist of up to eight Momentum devices. A network may contain up
to eight clusters.
The cable between devices in a cluster may be 10 in to 3 ft. The cable between
clusters or between a cluster and the trunk must be at least 10 ft.
The maximum length of the network continues to be 1500 ft. The maximum number
of devices in a network continues to be 64.
64 Nodes When a Modbus Plus network consists entirely of Momentum devices, then a
single section of cable may support 64 nodes instead of the standard 32 nodes.
Example: If a single SA85 is added to a network of Momentum modules, the
network is no longer Momentum only, but a mixture of devices. Each cable section
must be limited to 32 nodes. Cable sections must be connected by a repeater.
Note: Only Momentum devices are allowed in a cluster.

Two Types of Modbus Plus Networks
I/O Networks and
Supervisory
Networks
In a distributed control environment, Modbus Plus can be used in either of two
ways:
lAs an
I/O network
lAs a supervisory network
I/O Networks In a deterministic I/O network architecture, one CPU services up to 63 Momentum
I/O modules, Terminal I/O modules or other Modbus Plus devices.
Supervisory
Networks In a supervisory architecture, several intelligent processing devices share system
data with each other. Many kinds of devices may be part of the network. You should
be aware of each device’s requirement for access to the network and of the impact
each device will have on the timing of your network communication, especially
when servicing non-critical (and non-deterministic) I/O.
Continued on next page
CAUTION
CRITICAL I/O MUST BE SERVICED IN AN I/O NETWORK
Design your Modbus Plus architecture to meet the needs of your network. Modbus Plus can
offer deterministic I/O servicing or non-deterministic supervisory servicing of programming,
user interface, and third party ModConnect devices. Do not use a supervisory network to
service critical I/O.
Failure to observe this precaution can result in injury or equipment damage.
Note: When a programming panel or other human-machine interface (HMI)
device is used as part of a deterministic Modbus Plus I/O network, it
should be connected via the RS232 port on the CPU, not as a Modbus
Plus node.

184 870 USE 101 10 V.2
Two Types of Modbus Plus Networks, Continued
What if I Need
Both Types? If your system requires both supervisory and I/O handling architectures, one
solution is to use a Processor Adapter with I/OBus capabilities as the I/O network
and either a 172 PNN 210 22 or 172 PNN 260 22 Option Adapter with Modbus Plus
for the supervisory network.
Using the Modbus Plus Ports
870 USE 101 10 V.2 185
Standard Cabling Schemes
Introduction In a standard Modbus Plus cabling scheme, each peer device connects via a drop
cable to a tap along a trunk cable.
Length The maximum length of cable from one end of the network to the other is 1500 ft.
(450 m) if no repeaters are used.
You can use up to three Modicon RR85 Repeaters to extend the cable to up to
6000 ft. (1800 m). Each repeater allows you to extend the cable 1500 ft. (450 m).
Distance
Between Nodes Nodes must be separated by at least 10 ft. of cable. This requirement is more than
satisfied by standard drop cables:
Number of
Devices The maximum number of devices in a network is 64:
lIf you use only Momentum products, you may use up to 64 devices on one
cable section without a repeater.
lIf you use a mixture of devices, you may use up to 32 devices on one cable
section. You must use a repeater to connect to another cable section. You may
use up to three repeaters and four cable sections in all.
Termination You must terminate both ends of the network. If your network consists of two or
more sections separated by a repeater, each section must be terminated at both
ends.

Introduction In cluster mode, Momentum I/O devices may be placed in small groups, connected
by much shorter lengths of cable than in standard Modbus Plus cabling schemes.
You may use clusters and standard single nodes in the same network.
Length of
Network The maximum length of cable from one end of the network to the other is 1500 ft.
(450 m) if no repeaters are used.
You can use up to three Modicon RR85 Repeaters to extend the cable to up to

Modbus Plus Addresses
Introduction Modbus Plus devices function as peers on a logical ring. Each device accesses the
network by acquiring a token frame that is passed in a rotating address sequence.
Each device on a Modbus Plus network needs a unique address in the range
1...64. The device address determines the logical order in which the network token
will be passed from device to device.
Address
Sequence The assignment of addresses does not have to map to the physical layout of the
network–e.g., device 17 is placed physically before device 3. This is important to
understand because the network's token rotation is defined by device addresses-
e.g., device 2 will pass the token to device 3, device 3 to device 4, etc.
Illegal Addresses If you set the node address to 00 or to a value greater than 64:
lThe COM LED will go ON steadily to indicate an illegal address assignment.
lThe Run LED will flash 4 times.
lThe Processor Adapter will not run until you set a valid, unused address on the
Option Adapter and cycle power.
Continued on next page
CAUTION
COMMUNICATION ERRORS MAY RESULT
Do not install a Modbus Plus Option Adapter before you have set its Modbus Plus address
for your application. See your network administrator to get the Modbus Plus node address
for this module.
Failure to observe this precaution can result in injury or equipment damage.

Setting Modbus
Plus Addresses Two rotary switches on the Momentum Option Adapter are used to set the network
address. The top switch (X10) sets the upper digit (tens) of the address. The lower
switch (X1) sets the lower digit (ones) of the address.
Example of an
Address The illustration below shows a sample setting for address 14:

Peer Cop
What Is Peer
Cop? A Momentum M1 Processor Adapter has the ability to define point-to-point
transactions between itself and other devices on the Modbus Plus network. The
tool for defining these transactions is a panel software configuration utility known as
Peer Cop.
Configuring
Network Devices
with Peer Cop
Each device on the network can be configured to send and receive Peer Cop data.
lIn a Modbus Plus I/O networking architecture, the CPU on the network can be
used to configure the entire Peer Cop database.
lIn a Modbus Plus supervisory architecture, each CPU on the network needs to
be configured to handle the Peer Cop data that it will send or receive.
Four Types of
Data
Transactions
Peer Cop allows you to define four types of data transactions:
Sources and
Destinations Peer Cop uses defined data references (like PLC discretes or registers) as sources
and destinations. For example, a block of registers can constitute the data source
for the transmitting device, and that same or another block of registers can be the
data destination for the receiving device.
Continued on next page
Peer Cop Data
Transaction Function Maximum Data Length/Token Frame
Global Output Data to be broadcast globally
to all devices on the network
32 words
Specific Output Data to be transmitted to
individual devices
32 words/device
500 words to all specific devices

Peer Cop, Continued
How Peer Cop
Data Is Sent and
Received
The reception of Peer Cop source data and the delivery of Peer Cop destination
data are handled by the token rotation. The token is always passed to the next
logical device in the network’s address sequence.
Because all the Modbus Plus devices monitor the network, any one device can
extract the data addressed specifically to it. Likewise, all devices can extract global
data. Peer Cop then enables the Modbus Plus device currently holding the token to
direct specific data to individual devices and broadcast global data to all devices on
the network as part of its token frame.
Effect of Using
Peer Cop The net effect of using Peer Cop for data transactions is that each sending device
can specify unique references as data sources and each receiving device can
specify the same or different references as data destinations. When devices
receive global data, each device can index to specific locations in the incoming
data and extract specific lengths of data from those points. Data transactions
therefore happen quickly as part of the token rotation and can be directly mapped
between data references in the sending and receiving devices.

Changing the Range of Discrete and Register References
Introduction This section provides guidelines and a procedure for changing the range of discrete
(0
x
and 1
x
) and register (3
x
and 4
x
) references.
Guidelines When you change the range of discrete and register references, follow these
guidelines:
lAdjust the range of discretes in increments of 16. Sixteen discretes consume
one word.
lAdjust the range of registers in increments of 1. Each register consumes one
word.
lThe total number of register and discrete references cannot exceed 3k words.
lA minimum configuration of 16 0

Changing the Size of Your Application Logic Space
Introduction The number shown in the Size of Full Logic Area field in the Configuration
Overview screen indicates the total amount of memory available for your
application logic. You cannot directly enter this field to modify the value. You can,
however, change the amount of memory available by manipulating the size of other
fields in the Configuration Overview screen.
Example 1 If you reduce the size of the I/O Map area, the number in the Full Logic Area field
automatically increases. Say you are using a 12.0K machine and you change the
size of the I/O Map from the default value of 512 to 256–a decrease of 256 words.
The default Size of Full Logic Area will automatically increase from 1198 to 1454.
Example 2 Similarly, if you allocate some number of words to configuration extension memory
(to support Peer Cop), you will reduce the Size of Full Logic Area by the number of
words allocated the configuration extension memory.

Changing the Number of Segments
Introduction The number of segments specified in the Configuration Overview screen
determines the number of I/O Map drops that you will be able to set up for your
CPU.
The number of segments you will need depends on whether your Processor
Adapter will support an I/OBus network.
For I/OBus
Networks You must change the number of segments to 2 if you want to create an I/O Map to
support an I/OBus network.
For All Other
Cases The default number of segments (1) is correct. You only need one drop because
the only points to be I/O Mapped are those on the local base.

Changing the Size of the I/O Map
Introduction The default size of the I/O Map and your options vary, depending on whether or not
your Processor Adapter supports an I/OBus network.
Processors For
I/O Bus
Networks
With I/OBus, an I/O Map table is used to define the number, location, and type of
I/O devices on the network bus.
All Other
Processors Other Processor Adapters only use the I/O Map for local I/O. The default of 32
words is sufficient for any Momentum I/O base. Depending on the requirements of
your I/O base, you may be able to reduce the number of words to the minimum, 17,
in order to increase the size of the full logic area.

Establishing Configuration Extension Memory
Introduction By default, no memory space is allocated for configuration extension memory. If
you want to use the Peer Cop capability to handle Modbus Plus communications,
you need to define some configuration extension memory to enable Peer Cop.
Extension memory is specified as a number of 16-bit words. That number is
entered in the ExtSize entry of the Configuration editor. Once an adequate
number of words has been specified here, Peer Cop will be enabled in the CfgExt
pull-down list.
How Much
Memory? The minimum Peer Cop ExtSize memory requirement is 20 words; the maximum
is 1366 words.
Follow these guidelines for estimating the amount of extension memory you will
need for your Peer Cop database:

appropriate memory allocation to support your I/OBus network. A rule of thumb for
roughly estimating the number of words required for I/O Mapping is:
l16 words for overhead
l10 words/module on the network (including both the local and the network I/O)
The idea behind adjusting the memory size is to allow you to completely I/O Map
your network while preserving as much user memory as possible for your
application program.

Network in Modsoft with Peer Cop
At a Glance
Purpose Communication transactions over Modbus Plus are defined in Modsoft 2.6 by a
configuration tool called Peer Cop. This section uses examples to explain how to
use Peer Cop to configure the two types of network architecture:
lAn I/O network, where the Peer Cop of the CPU defines all the communication
transactions over the full network.
lA supervisory network with two or more CPUs communicating with each other
and with additional devices on the network.

Defining the Link and Accessing a Node
Overview When you reach the default Peer Cop screen, a popup menu asks you to define a
link and access a node.
What Is a Link? The
link
is the Modbus Plus network on which the CPU resides.
The only valid link value for a Momentum M1 CPU is 1. An M1 can function only on
one Modbus Plus network–multiple Modbus Plus links are not supported.
What Is a Node? The
node
is the Modbus Plus address of one of the I/O devices on the network.
A valid node value in our example is any number in the range 2...5. For our
example, we will first access the170 ADI 340 00 16-point input module at Modbus
Plus address 2.
Continued on next page
Note: Address 1, the network address of the CPU itself, is not a valid node to
access since the CPU does not need to access itself over the network.

Confirming the Peer Cop Summary Information
Overview Once you have defined the link and accessed a node, the Peer Cop summary
information values assume default settings. This section describes those settings
and how to confirm or change them.
Timeout The default Timeout is 500 ms.
Timeout
is the maximum interval that Modbus Plus on a Peer-Copped device will
remain healthy without communication activity. If this interval is exceeded, the
device will clear its network health bit and will no longer try to communicate via
Modbus Plus.
The timeout interval must be in the range 20 ... 2000ms, and it must be specified as
an increment of 20ms.
For our example, we will change the timeout value to 240ms.
On Error The default On Error setting is CLEAR.
The
On Error
setting specifies how the Peer-Copped device will treat the last
values received before a timeout, once Modbus Plus communications have been
restored.
One of two settings may be used–CLEAR or HOLD. CLEAR sets all the previously
received values to 0, and HOLD retains the previous values.
For our example, we will change the setting to HOLD.

Introduction The Peer Cop screen is now set to access the device at Modbus Plus address 2,
which for this example is a 170 ADI 340 00 16-point input module.
This section explains how to specify the reference for input data from this module.
Device
Requirements When you use Peer Cop to handle a Modbus Plus I/O architecture, you need to be
aware of the type of I/O you are configuring at each network address. Peer Cop
does not know that the device at address 2 is a discrete 16-point input module.
You need to know that a specific input reference with a length of one word (16 bits)
is required to handle this module.
We will assign a 3
x
register (300016) as a specific input to the CPU. When the 170
ADI 340 00 sends input data to the CPU, it will be sent to this register.

Configuring a Node to Exchange Data
Getting Started To Peer Cop this sample configuration, each CPU must be separately programmed
to communicate with the others over Modbus Plus. Begin by connecting your
programming panel to the 171 CCS 760 00 Momentum M1 device at Modbus Plus
address 2. Access the Peer Cop with your Modsoft 2.6 software.
When you reach the default Peer Cop screen, you need to initialize the summary
information region. To do this, define a link value and a node value in the Add Node
popup.
What Is a Link? The
link
is the Modbus Plus network on which the CPU resides.
The only valid link value for a Momentum M1 CPU is 1. An M1 can function only on
one Modbus Plus network–multiple Modbus Plus links are not supported.
What Is a Node? The
node
is the Modbus Plus address of one of the I/O devices on the network.
For our example, we will first access the AT984 supervisory PLC at Modbus Plus
address 1.

Confirming the Peer Cop Summary Information
Overview Once you have defined the link and accessed a node, the Peer Cop summary
information values assume default settings. This section describes those settings.
Timeout The default Timeout is 500 ms.
Timeout
is the maximum interval that Modbus Plus on a Peer-Copped device will
remain healthy without communication activity. If this interval is exceeded, the
device will clear its network health bit and will no longer try to communicate via
Modbus Plus.
The timeout interval must be in the range 20 ... 2000 ms, and it must be specified
as an increment of 20 ms.
For our example, we will use the default setting.
On Error The default On Error setting is CLEAR.
The
On Error
setting specifies how the Peer-Copped device will treat the last
values received before a timeout, once Modbus Plus communications have been
restored.
One of two settings may be used–CLEAR or HOLD. CLEAR sets all the previously
received values to 0, and HOLD retains the previous values.
For our example, we will use the default setting.

Preparing to Save to Flash
Before You Save
to Flash Before you can save to Flash in Modsoft, you need to specify how the controller will
react when power is re-established. This section describes three options. The next
section describes how to specify an option.
Three
Parameters Modsoft will ask you three questions:
Q1 Continue power down Run state? Y/N
Q2 Start PLC after download? Y/N
Q3 Continue? Y/N
Q1 and Q2 define the state of the controller after power is re-established. Q3
simply initiates a save-to-Flash operation in the controller. Q3 cannot be invoked
unless Q1 and Q2 have been answered Y(es) or N(o).
Three Possible
States The following table shows you the three states that you may specify for the
controller:
If the Answer Is ... Then the Controller ...
Q1 = Y Comes back in the state it was in (Running or Stopped) before
power was lost
Q2 = N
Q1 = N Comes back Running when power is restored
Q2 = Y
Q1 = N Comes back Stopped when power is restored
Q2 = N

Changing the Size of the Full Logic Area
Introduction The number shown in the Available Logic Area field in the PLC Configuration
screen indicates the total amount of memory available for your application logic.
You cannot directly enter this field to modify the value. You can, however, change
the amount of memory available by manipulating the size of other fields in the PLC
Configuration screen.
Example 1 For example, if you reduce the expansion size of the I/O Map, the number in the
Available Logic Area field automatically increases. Say you are using a 12.2K
machine and you change the size of the I/O Map from 512 to 256, a decrease of
256 words. The Available Logic Area will automatically increase from 1198 to 1454.
Example 2 Similarly, if you allocate some number of words to the Peer Cop expansion size,
you will reduce the Available Logic Area by the number of words allocated for Peer
Cop.

Understanding the Number of Segments
Only the First
Segment is
Solved
The number of segments specified in the Configuration Overview screen
determines the number of I/O Map drops that you will be able to set up for your
CPU. When you are using Concept 2.2, the default number of segments is 1 in
most CPUs.
This number is adequate for all processor adapters and does not need to be
changed. However, you should only use the second segment for I/OBus I/O
mapping or other subroutines.
Configuring an M1 CPU with Concept
322 870 USE 101 10 V.2
Changing the Size of the I/O Map
Introduction The default size of the I/O Map is 144 words. You may want to adjust this number to
provide more support for an I/OBus network or to increase the size of the full logic
area.
Processors for
I/OBus Networks With I/OBus, an I/O Map table is used to define the number, location and type of
I/O devices on the network bus.
All Other
Processors Other Processor Adapters only use the I/O Map for local I/O. The default of 144
words is more than sufficient for any Momentum I/O base. Depending on the
requirements of your I/O base, you may be able to reduce the number of words to
the minimum, 4, in order to increase the Available Logic Area.

Setting the Time
Overview Once you have reserved a block of registers for the time-of-day clock, you have to
set the correct time. With Concept, you must go online and set the register bits
individually, using the following guidelines for setting the status bits and setting the
time bits. The CPU must be running.
Setting the
Status Bits The control register (4
x
) uses its four most significant bits to report status:
Setting the Time
Bits The following table shows how the registers handle time-of-day clock data, where
register 4

Configuring I/O
Overview Once the Ethernet port address parameters have been set, you may assign
parameters for I/O scanning.
Health Block Specify the starting register of the register block which will contain the health bits
for each of the IO Scanner transactions that you intend to configure.
If you designate a 3x register, the health bits for 64 transactions (maximum) will be
stored in 4 contiguous registers starting at the address you specify.
If you designate a 1x register, the health bits will be stored in 64 contiguous
discrete registers.
A health bit is set only if the associated transaction has completed successfully
within the last health timeout period for that transaction (see below). When the PLC
is started, all configured transactions have their respective health bit preset to 1. If
the transaction subsequently fails, then the health bit is cleared after the
programmed health timeout period has expired.

on the down arrow and selecting it, as shown:
Unit ID If the slave module is an I/O device attached to the specified slave module, use the
Unit ID column to indicate the device number.
Health Timeout Use this column to specify the length of time in ms to try the transaction before
timing out. Valid values are 0 ... 65,000 ms (1 min). To avoid timing out, specify 0.
If you specify a time, after the specified time without a valid transaction, the health
bit will be reset to zero.
Rep Rate Use this column to specify how often in ms to repeat the transaction. Valid values
are 0 ... 65,000 ms (1 min). To repeat the transaction continually, specify 0.

Introduction Every M1 Processor Adapter is assembled on an I/O base. The I/O points on the
base are the local I/O for that processor.
As part of the configuration process, you need to create an I/O Map for the local
I/O. The I/O Map assigns the appropriate range and type of reference values (0
x
,
1
x
, 3
x
, or 4
x
) from the CPU’s state RAM to the input and/or output points on the
local base unit.

Supporting an I/O Map for an I/OBus Network
Introduction Three Processor Adapters have an I/OBus communication port that enables them
to control and communicate with other network slave I/O:
l171 CCS 760 00
l171 CCC 760 10
l171 CCC 960 20
l171 CCC 960 30
If you are using I/OBus to control network I/O, you need to write an I/O Map in your
configuration. This section describes the configuration parameters required to
support an I/O Map for I/OBus.
I/O Map
Reserved Words Be sure that you have reserved enough words for I/O mapping to support your I/O
Bus network. The default setting is 144 words. To estimate the number of words
you require, allow:
l16 words for overhead
l10 words/module on the network (including both the local and the network I/O)
Allot sufficient memory to completely I/O Map your network, while preserving as
much user memory as possible for your application program.
Number of
Segments Be sure that the number of segments is set to 2. If you have changed this setting to
1, you will not be able to support an I/OBus network.
Next Step Once you are sure that your Configuration Overview parameters are set properly,
you can access an I/O Map screen for an I/OBus network.

InterBus device manufacturers embed an identifier code in their network slave
modules in conformance with InterBus standards. The code identifies a device by
its I/O type but not its specific model or name.
I/OBus recognizes the InterBus identifier codes provided below and allows you to
I/O Map devices that use these codes. However, you cannot use the module zoom
screens to define the parameters for these InterBus modules.

Device
Requirements When you use Peer Cop to handle a Modbus Plus I/O architecture, you need to be
aware of the type of I/O you are configuring at each network address. Peer Cop
does not know that the device at address 2 is a discrete 16-point input module. You
need to know that a specific input reference with a length of one word (16 bits) is
required to handle this module.
We will assign a 3

DX Loadable Support
Introduction The M1 CPUs can use DX loadable instructions, which support optional software
products that can be purchased for special applications. DX loadables provide the
user with special ladder logic functions.
Loaded on
Page 0 The code for DX loadables gets loaded into the Page 0 area. Thus, for every word
of DX loadable that is loaded, one word of Page 0 becomes unavailable for other
use (such as application logic).
Limited
Functionality DX loadables are limited in the functionality they can provide because they do not
provide storage for variables and are limited in their size.
M1 Support M1 supports only loadables targeted for 80x86 microprocessors running in 16-bit
real mode that have not made any hard-coded hardware assumptions (e.g., the
address and format of the TOD clock). Obviously, there must be enough available
memory to fit the loadable.
Saved to Flash Since DX loadables are stored in Page 0 memory, they are saved whenever a
save-to-Flash operation is initiated.

A Special STAT Instruction
Overview A special version of the STAT instruction has been developed to support
Momentum M1 CPUs. The STAT instruction accesses a specified number of words
in a status table in the CPU’s system memory. Here vital diagnostic information
regarding the health of the CPU and the I/OBus I/O under its control is posted.
From the STAT instruction, you can copy some or all of the status words into a
block of registers or a block of contiguous discrete references.
This section describes the STAT instruction.
Avoid Discretes We recommend that you do not use discretes in the STAT destination node
because of the excessive number required to contain status information.
Specify Length The copy to the STAT block always begins with the first word in the table up to the
last word of interest to you. For example, if the status table is 20 words long and
you are interested only in the statistics provided in word 11, you need to copy only
words 1...11 by specifying a
length
of 11 in the STAT instruction.
Diagram of STAT
Block The STAT block includes a top node (for destination) and a bottom node (for
length). The STAT block is represented in the following illustration.

Top Node
Content The reference number entered in the top node is the first position in the destination
block–i.e., the block where the current words of interest from the status table will be
copied. The reference may be:
lThe first 0x reference in a block of contiguous discrete outputs
lThe first 4x reference in a block of contiguous holding registers
Bottom Node
Content The integer value entered in the bottom node specifies the number of registers or
16-bit words in the destination block where the current status information will be
written.
The length–i.e., number of words–in the status table will vary depending on
whether or not I/OBus I/O is being supported:
lWithout I/OBus, the STAT instruction is 12 words long.
lWith I/OBus, the instruction is 20 words long.
