Introduction

1.1 Description

1.1.1 The LM10 Relay

The GE Multilin LM10 Motor Protection System is a modular device designed to protect

motors from various fault conditions. This device interfaces with a DeviceNet network. The

network will monitor and control the relay status and functions. The relay also has the

capability of operating in a standalone mode. Configuration can be accomplished via DIP

switches on the front of the relay.

Additionally, the relay has an interface port to communicate to the LM10 programming

and display unit (PDU). The PDU is a self-contained device consisting of a membrane switch

keypad, a liquid crystal display (LCD), and control electronics for communication with the

relay. This unit provides a method of configuring and monitoring the LM10. The PDU

incorporates an RS232 interface with a proprietary communications protocol.

DeviceNet is a registered trademark of Open DeviceNet Vendor's Association (ODVA).

1–2 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

OVERVIEW CHAPTER 1: INTRODUCTION

1.2 Overview

1.2.1 Features

The LM10 Motor Protection System is a microprocessor-based unit. It takes a ‘snapshot’

image of the three phases of current, one phase of voltage, and ground. The data is then

applied to the algorithms and compared to the device's configuration information. Based

on the result of the comparison, the relay may trip one or more of the on-board control

relays. When applicable, indicators will be illuminated to show the status of the device.

Additionally, up to ten trip events will be stored in non-volatile memory.

The LM10 auxiliary communications port to the PDU is an RS232 interface using a

standard four-pin RJ11 style cable. This port will allow the PDU to obtain and display any of

the real-world data that is contained in the relay as well as to configure the relay.

The LM10 Motor Protection System supports the DeviceNet protocol and can be interfaced

with the PLC DeviceNet mastercard or DCS Scanner card. It supports Polled, Change of

State (COS), Cyclic I/O Messaging, and Explicit Messaging.

1.2.2 Current and Voltage Inputs

The relay has inputs for two sets of three-phase current transformers (CTs) and one ground

CT. One set will allow for custom 27 A and 90 A CT sensor packs to be connected; the other

will allow for 75 to 800:5 A ratio CTs. Dual speed motors will require two separate CTs

connected in parallel.

A 100:1 A core-balance CT or 20 A ground fault sensor pack can be connected to the

ground CT terminals for ground current measurement.

Provisions have been made to support various CTs for the three-phase measurements.

Voltage input from the control power transformer (CPT) is conditioned and measured by

the analog-to-digital converter to determine supply voltage. This signal, in conjunction

with the current, is used to calculate power and power factor.

1.2.3 Relay Outputs

The LM10 Motor Protection System contains 4 on-board Form-C relays with NEMA C150

pilot duty ratings. Two relays should be used to control the coils of motor contactor and

one to annunciate ground fault status. An additional programmable relay is available for

fault status indications.

The two control relays are labeled “RUN 1” and “RUN 2”. These relays are enabled on

command from the control logic. If the LM10 detects a fault condition the relays will be de-

energize, causing the motors to shut down.

The ground fault relay is energized on detection of a ground fault. Upon correction of the

ground fault condition, the relay will be de-energized. The output contact can be used to

trip a breaker or annunciate to other devices.

The programmable trip relay is energized when the programmed algorithm conditions

have been met and can annunciate out to other devices.

CHAPTER 1: INTRODUCTION OVERVIEW

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–3

1.2.4 Power Supply

The LM10 Motor Protection System has an on-board power supply with a fuse that

converts the AC input to the levels necessary to operate this device. The operating range is

96 to 140 V AC, nominal 120 V control power (80% to 117%). The supply has

programmable auto-restart capability of up to 4 seconds. This also supplies necessary

power to the PDU at a TTL.

For correct measurement of power and power factor, the control power must be

connected across phase A and phase B of the three-phase power supply.

FEATURES CHAPTER 1: INTRODUCTION

1.3 Features

1.3.1 Programming and Display Unit

The main task of the programming and display unit (PDU) is to provide status information

to a local user. The PDU can display the requested parameter(s) on the LCD in either English

or Spanish. Additionally, the PDU can be used to configure the LM10 via the RS232 serial

communications port.

1.3.2 LED Indicators

The LM10 has five (5) LEDs on the front panel. They function as follows:

•Module Status (MS): This two-colored LED is used for the DeviceNet module status. Its

function is defined in the DeviceNet specification.

•Network status (NS): This two-colored LED is used for the DeviceNet network status.

Its function is defined in the DeviceNet specification.

•Overcurrent (OC): This red LED is illuminated when the relay detects an overcurrent

condition in one or more of the power phases.

•Ground Fault (GF): This red LED is illuminated when the relay detects a ground fault

condition.

•Current Unbalance (CUB): This red LED is illuminated when the relay detects a current

unbalance between the power phases.

1.3.3 Switches

The following switches are located on the front panel of the LM10. Changes to switch

settings will not take effect until power is cycled (on-off).

All other relay features (e.g., the CT sensor pack) can only be programmed via DeviceNet or

the RS232 configuration port.

•MAC ID: Two rotary DIP switches are used to set the DeviceNet MAC ID. Each unit on

the DeviceNet network requires a unique MAC ID. The valid ID range is from 0 to 63,

with a factory default of 0. Cycle power after any switch changes.

•Baud rate: This two-position DIP switch is used to select the DeviceNet baud rate. The

valid rates are 125K, 250K and 500K bits per second. The DIP switch is defaulted to

125K baud rate when shipped.

Changes to switch settings will not take effect until the next power cycle.

•Trip Class (TC): NEMA overload trip class is selected using a rotary DIP switch. Valid

settings are Class 10, 15, 20, or 30. To set the trip class, align the screwdriver slot with

the desired value. Do not use the triangle marker on the DIP switch. A screwdriver with

a nominal blade width of 0.094 to 0.175 inches should be used. Smaller blades could

allow the switch to be set in an invalid position.

Changes to switch settings will not take effect until power is cycled.

4.1 Overcurrent Fault Conditions

4.1.1 Descriptions

When current for any of the three phases becomes greater than the nominal full load

current (FLA), the unit calculates time to trip. The FLA, trip class, CT ratio and number of

passes/turns through the CT, and current input readings are taken into account. Separate

algorithms are used for “cold” and “hot” motors. Since the LM10 does not measure

temperature directly, motor condition is extrapolated from operating current versus the

FLA setting.

The FLA value can be set from 1.2 to 800 A in steps of 0.1. This fault value is monitored

continuously and can not be disabled.

The motor “hot” condition is determined based a variable algorithm. Once a fault condition

is reached, the unit may not be Reset until an appropriate cool-down period has elapsed.

This is once again calculated based on FLA, trip class, CT ratio and number of passes/turns

through the CT, and current input readings.

The time to trip is a function of percent overcurrent, trip class, and motor condition (cold or

hot). The current level must exceed 1.2 ×FLA for the trip timeout to run. This time is

cumulative and will not time in unless the level drops below 1.0 ×FLA.

A class 10 motor has the shortest trip times while a class 30 has the longest. The trip class

should be selected based on motor size and type (see Switches on page 1–4 for details on

setting the trip class).

The LM10 monitors average current of the three phases over time to determine the motor

condition.

FIGURE 4–1: Cold Motor Trip Curves

FIGURE 4–2: Hot Motor Trip Curves

CHAPTER 4: FUNCTIONALITY OVERCURRENT FAULT CONDITIONS

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–27

4.1.2 Trip Curves Example

A trip curves example with jam and stall enabled is shown below. In this example, we have

trip class 20, cold motor, with jam at 150% FLA for 120 seconds, and stall at 600% FLA for

12 seconds.

FIGURE 4–3: Trip Curve with Jam and Stall Enabled

The LM10 will trip on a jam or stall condition if these faults are enabled (see Run 1 and Run

2 Setup on page 4–32). The overcurrent curve cannot be disabled. Therefore, if the jam or

stall values are set greater than the time allowed by the standard trip curve, the LM10 will

trip before a jam or stall condition can be reached.

Upon an overcurrent, jam, or stall fault, the LM10 forces a cool-down period before the

motor may be restarted. The time to reset is calculated as a function of the trip class and

percent of full load current (FLA) at the time of the trip. For example, a class 30 motor

tripping on a 6 ×FLA fault will take 9 times longer before it is ready to reset than a class 10

motor tripping on a 2 ×FLA fault.

FIGURE 4–4: Cool Down Times

4–28 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

OVERCURRENT FAULT CONDITIONS CHAPTER 4: FUNCTIONALITY

While the motor is in the cool-down time delay, the PDU status screen will display the fault

type followed by a number decrementing from 99. When the number counts down to 0, the

message “Ready to Run” will be displayed to indicate the RESET button may be pressed.

Once the LM10 is successfully reset, the user may activate the run command.

CHAPTER 4: FUNCTIONALITY CONFIGURATION SETTINGS

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–33

•FLA (full load current) The LM10 Motor Protection System is designed to work in

conjunction with a spectrum of motor starters. Therefore it handles full load currents

ranging from 1.2 to 800 amps. The correct FLA for the motor in use must be

programmed for relay protection to function properly.

Enter the full load current (FLA) of the motor. The LM10 will not accept full load currents that

exceed the CT or sensor pack rating; however, lower values are acceptable. For best results,

enter the proper FLA for the motor being used. Refer to Overcurrent Fault Conditions on

page 4–25 for additional details.

•Ground Setup: A zero-sequencing ground fault can be enabled to trip and operate a

separate ground fault relay when ground fault current exceeds the Ground Setup

Fault setpoint. The Ground Setup Time Delay setting is from 0.5 to 2.5 seconds.

Ground current can be continuously monitored at the PDU or over the network.

A ground fault CT or sensor shall be connected for this protection.

•JAM Setup: According to NEMA or IEC MG 1-1998 part 12, page 21, “polyphase motors

600 V or less not exceeding 500 hp shall be capable of withstanding a current not less

than 1.5 times the full load rated current for not less than two minutes when the

motor is at normal operating temperature.” For relatively low overcurrent conditions,

particularly on higher NEMA class motors, trip times could be considerably longer than

2 minutes. Therefore, a separate jam fault is available as the standard time

overcurrent curve may not protect in this range.

The user may set a JAM Setup Fault level of 100 to 250% of FLA or disable this function.

The default setting is set to disabled.

The overcurrent curve cannot be disabled. Therefore, if the JAM Setup Time Delay is set

greater than the time allowed by the standard trip curve, the LM10 will trip before a Jam

condition can be reached. See Trip Curve with Jam and Stall Enabled on page 4–27 for an

example of the effect of trip times.

•STALL Setup: Cold motor trip times for a 6 ×FLA fault are determined by trip class. For

example, a NEMA class 20 motor at 6 ×FLA would trip in 20 seconds. A separate Stall

fault is available which would allow the user to reduce the trip time for large

overcurrent situations.

The user may set a STALL Setup Fault level of 330 to 600% of FLA or disable this function.

The default setting is disabled.

The overcurrent curve cannot be disabled. Therefore, if the STALL Setup Time Delay is set

greater than the time allowed by the standard trip curve, the LM10 will trip before a stall

condition can be reached. See Trip Curve with Jam and Stall Enabled on page 4–27 for an

example of the effect of trip times.

•CurUnB Setup (current unbalance setup): The LM10 monitors the three current phases

and trips if the phases are unbalanced. In addition to phase A, B, and C current, this

function takes FLA, CT ratio and number of passes/turns through the CT into account.

If the average current exceeds FLA, then this average value is used in the formula

instead of the FLA value. The formula is:

(EQ 4.1)

The next formula uses the largest Δ of the three phases.

(EQ 4.2)

The default CurUnB Setup Fault value is “Disabled” since not every application will require

current unbalance monitoring. The current unbalance is programmable between 2 to 25%

of FLA.

Δphase current average current–=

unbalance level ΔFLA⁄()100%×=

4–34 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

CONFIGURATION SETTINGS CHAPTER 4: FUNCTIONALITY

A 6% voltage unbalance equates to a roughly 25% current unbalance and will frequently

cause motor damage.

•LdLoss Setup (load loss setup): Load loss is based on watts, defined as follows:

(EQ 4.3)

The power factor is determined using the phase relationship between voltage and phase C

current readings. Full load would be when the average current is at FLA, voltage is at

nominal value, and power factor equals 0.85. This would equate to a load loss level of

100%. The LdLoss Setup Fault trip point is programmable as a percentage of this value.

The motor would need to drop below this level for the preset time to cause the load loss

fault. The relay is shipped with this option disabled.

4.2.7 Time Delays

PATH: Configuration ØØØØØ Time Delays

The time delay settings are described below.

•AuxSns1 and AuxSns2 (auxiliary sense failure): Should the LM10 detect that a

contactor did not open/close according to its command, an auxiliary sense (AuxSns)

trip failure will be recorded in the fault record and shut down the run relay. This fault is

factory preset at 0.4 seconds. The delay time for closing the relay can be changed

however opening time is set at a constant 0.4 seconds to detect contact welding.

Applications requiring a delay between the run command and the starter pulling-in can be

accommodated using this feature (for example, fans requiring damper closer before

running). The AuxSns1 and AuxSns2 time delays can be set to match the damper closure

time.

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–35

One or more optional faults may be enabled after the basic functions are configured.

•U/O Volt En (undervoltage/overvoltage enable): This setting enables or disables the

under/overvoltage element. LM10 revisions 1.40 and lower do not support this setting.

Maximum and minimum voltage trip points are hard coded in the device and are not user

programmable. These points are approximately 80% and 117% of nominal voltage. This

corresponds to 96 V and 140 V with 120 V nominal voltage.

•Maintained (maintained switching): This setting distinguishes between maintained

(latched) versus momentary AC input switches. This is only applicable to Manual

control, and has no effect on control via DeviceNet. The default setting is “off” for

momentary switches. No seal in contact is required. In the maintained mode a run

switch must stay closed if opened the LM10 will stop the motor. The stop switch input

for safety reasons will interrupt the run relay in maintained or momentary mode. If the

run switch is on when the stop command is given, it will need to be turned off and

back on to get the motor running again. The stop command also interrupts the run

relay if controlled by the network. The network will need to send another run

command to restart the motor.

When using the maintained switching feature, potential safety hazards must be

considered and an appropriate setup chosen for each individual application.

•Auto Restart (power loss when running): The LM10 will be able to recover from a

power loss of up to 4 seconds and return to its previous run state. Enabling

autorestart allows the unit to restart the motor without operator intervention using a

momentary run input. The default condition is “off” – this would require the operator

to restart the motor after the LM10 regains power.

Other conditions may interfere with this operation. A fault condition like voltage or

DeviceNet may trip the LM10. Under the voltage condition the LM10 would be faulted

prior to power loss and not be in run when power is lost, therefore no run state to

restart. With the DeviceNet fault enabled, the power recovery would reset the

DeviceNet connections and the DeviceNet would act as if it's not communicating thus

a DeviceNet fault.

Potential safety hazards must be considered and the appropriate setup chosen for each

individual application.

•DevNet Fault (DeviceNet fault): If enabled, the LM10 will consider DeviceNet network

failures as a fault, tripping relay(s) and recording into the history record. Default

condition is enabled.

•50Hz Sys (50 Hz system): The default setting is for a 60 Hz system; use this menu item

to select a 50 Hz system instead. This does effect the sampling buffer and internal

calculations. Setting this improperly will result in some inaccuracies.

•Poll Data (poll data group): This setting selects the pre-defined group of parameters in

the DeviceNet input poll data. Refer to Poll Data on page 5–45 for details. LM10

revisions 1.40 and lower do not support this setting.

For this setting, group 1 is 7 bytes, group 2 is 12 bytes, group 3 is 22 bytes, group 4 is 7

bytes.

Poll group 4 option (7 bytes) is available only for firmware rev 1.70 and higher.

If PDU v1.70 or higher is used for LM10 firmware v1.6x and lower, Poll Data group 4 (which

is unavailable in firmware v1.6x and lower) will be displayed in the PDU but cannot be set

to the MPR unit.

•Reset Run Hrs (reset motor running hourse timer): The user may desire to reset the

motor running hours after replacement or maintenance. Note that hours are stored in

full-hour increments up to 65535. Typical bearing life is less than 50000 hours. Please

note that shutting down the unit will lose any partial hour accrued.

MOTOR START/STOP LOGIC CHAPTER 4: FUNCTIONALITY

4.5 Motor Start/Stop Logic

LM10 is designed to run in RUN1 and RUN2 mode. However, to illustrate this, only RUN1

mode is described below. The block logic diagram for RUN1 operation is shown in fig. 4-5.

Motor Status: Running 1

The relay can receive the RUN1 Start command as follows:

1. Start command through hardware RUN1 switch input

2. The RUN1 command is selected from the PDU in the configuration mode (used

for Test only)

3. Autorestart: the LM10 automatically returns to RUN1 operation after a power

loss of up to 4 seconds provided the autorestart setpoint has been enabled

and motor was running in RUN1 mode before the power loss

4. A start command is issued remotely through DeviceNet.

A PDU logged-in for configuration will disable run commands from both DeviceNet and

hardwired switches.

Motor Stop

Once the motor is in RUN1, it can be stopped as follows:

1. User asserts a hardware STOP switch Input

2. User de-asserts the RUN1 Hardware switch input (Maintained switch setting

set to ON)

3. A STOP command issued through a PDU Running Operations command (When

RUN1 command issued from PDU)

4. A stop command issued through DeviceNet

5. The relay trips on a protection function operation

6. RUN2 start command issue

7. The relay changed from USER mode to CONFIGURATION mode.

AUX Sense 1 Fault

Aux. Sense 1 fault for open contactor is detected if the main contactor status is still open

after 0.1 to 25.0 seconds (user settable) of the RUN1 O/P signal has been issued. The

contactor status is fed back to the relay through the AUX. Sense switch Input.

CHAPTER 4: FUNCTIONALITY MOTOR START/STOP LOGIC

5.1.12 Special Application

The LM10 Motor Protection System has a DeviceNet interface. The DEVICENET CONTROL

input will set the RUN control to be operated using the DeviceNet interface. For this

application we will assume this input to be tied active. This will disable any hard-wired

120 V AC RUN inputs from being accepted as a command to the LM10. The LM10 can read

the state of these inputs through the DeviceNet protocol.

With the use of this read request the DeviceNet scanner (PLC or Master) can check the

state of the local switches. After evaluating that all conditions of the system are

appropriate the RUN command can be sent to the LM10 through the DeviceNet link. The

RESET and STOP inputs do remain active at all times. The STOP input will command the

LM10 to stop the motor even though the DeviceNet is the controlling input. The DeviceNet

scanner would be able to detect this stop by monitoring the LM10 status. The status word

can be polled or setup as a Cos/Cyclic.

Auxiliary sense inputs are also activated by a 120 V AC signal. If the end user desires, he

may use these inputs for an alternate purpose if the Auxiliary Sense capability of the LM10

is disabled. The data is part of the same word as the RUN inputs.

DEVICENET OPERATIONS CHAPTER 5: COMMUNICATIONS

This data was initially setup for development purposes. An explicit message through the

custom class 100(0x64) is the only way to access this data. The DeviceNet message to read

this data is: service 0x0e, class 0x64, instance 1, and attribute 0x34. The response will be a

16-bit word with MACID switches in the high byte and AC switch input bits in the low byte.

• Sent by scanner: CANID, MACID, 0x0E, 0x64, 0x01, 0x34

• Response from the LM10: CANID, MACID, 0x8E, LBY, HBY

The format of this data follows F25: Input Switch Status. The high byte (HBY) is not used in

this application. The low byte (LBY) is the input data we are looking for. The seven hard

wired inputs map to bits 0 to 6 as DeviceNet Control, AxSn2, AxSn1, RUN2, RUN1, Reset,

Stop. To watch for RUN1 one would test for bit 2 being on. EX: LBY and 0x04 is not equal to

0x00.

Do not switch out of DeviceNet Control while the motor is running. In such a case the LM10

will issue a Stop command under the assumption that the network is down.

A.1 DeviceNet Overview

A.1.1 Description

DeviceNet™ is an open low-cost digital, multi-drop network based on the reliable CAN

technology to interconnect industrial devices (such as limit switches, photoelectric

sensors, valve manifolds, motor starter, process sensors, panel displays, etc.) via a single

network. This eliminates expensive wiring and failure due to the increase of number of

connections. It also reduces the cost and time to install industrial automation devices while

providing reliable interchangeability of components from multiple vendors. The direct

connectivity provides improved communication between devices as well as important

device-level diagnostics not easily accessible or available through hard-wired input/output

interfaces.

DeviceNet systems can be configured to operate in a master-slave or a distributed control

architecture using peer-to-peer communication. DeviceNet systems offer a single point of

connection for configuration and control by supporting both input/output and explicit

messaging. DeviceNet also has the unique feature of having power on the network. This

allows devices with limited power requirements to be powered directly from the network,

reducing connection points and physical size.

DeviceNet permits the interchangeability of simple devices while making interconnectivity

for more complex devices possible. In addition to reading the state of discrete devices,

DeviceNet provides the capability of reading analog data such as temperatures, load

current or to count the number of items that have passed on a conveyor belt in the given

period.

A–2 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

DEVICENET OVERVIEW CHAPTER A:

A.1.2 Controller Area Network (CAN)

The Controller Area Network (CAN) is a broadcast-oriented communications protocol.

DeviceNet uses CAN for its data link layer. The CAN protocol has a fast response and high

reliability for demanding applications such as control of anti-lock brakes and air-bags.

Devices are now available for the industrial automation market demanding stability in high

temperature and high noise immunity.

A.1.3 DeviceNet Operations

DeviceNet is a connection based protocol; that is, all devices should establish a connection

prior to exchanging information. DeviceNet adopts the object modelling approach – all

information is structured in different objects. Services (such as Get and Set) can be applied

to these objects to extract/change information. The following are the typical object classes

found in a DeviceNet product:

1. Identity object. Identification information (such as vendor ID, device profile, revision,

etc.) of a device are stored in this object. Users can identify a particular object by

remotely access to this object.

2. Message Router object. This object handles the explicit messages received by routing

it to the proper destination objects.

3. DeviceNet object. A DeviceNet product will typically have a single instance of the

DeviceNet object. This instance would have as attributes: node, address, or MAC ID,

baud rate, bus-off action, bus-off counter, allocation choice, and the master MAC ID.

The only required service is Get_Attribute_Single.

4. Connection object. This object handles the connection of the module, such as Explicit

Messaging or Input/Output Messaging. Explicit messages contain attribute

addressing, attribute values and a service code describing the desired action. Input/

output messages contain nothing but data. In an input/output message, all

information about how to process the data is contained in the Connection object

associated with that I/O message

5. Assembly object(s). A DeviceNet product typically has one or more optional Assembly

objects. The primary purpose of these objects is to group different attributes (data)

from different application objects into a single Attribute.

6. Parameter object. The optional Parameter object is used in parameter-based devices.

One instance would be presented for each configurable parameter. The Parameter

object provides a standard method for a configuration tool to access all parameters.

Attributes of the Parameter object could include values, ranges, text strings, and limits.

7. Application objects. Usually at least one application object besides those from the

Assembly or Parameter class will be present in a device. There are a number of

standard objects in the DeviceNet object library.

Each object has its own parameters called attributes (such as vendor ID). The behavior of a

device is governed by these attributes.

Once the connection is established, all the data exchanged across this connection are

handled by the corresponding connection instance.

CHAPTER A: DEVICENET OVERVIEW

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–3

A.1.4 Explicit Messaging and Input/Output (I/O) Messaging

Explicit messages contain information such as vendors, parameters, etc. of a device. This

information is comparatively less important than the I/O message; as such, it is sent with a

higher CAN identifier as not to disturb the exchange of I/O messages on the bus.

Input/Output (I/O) messages contain the real-time I/O information of a device. In order to

achieve “real time”, these messages are sent as quick as possible; therefore, they are sent

with a lower CAN identifier than explicit messages.

A.1.5 Pre-defined Master/Slave Connection Set

A set of connection identifiers known as the Pre-defined Master/Slave Connection Set has

been specified to simplify the movement of I/O configuration-type data typically seen in a

master/slave architecture. An important benefit is that the establishment of connections

from the pre-defined set is simplified considerably. Only a few messages are required to

have I/O connections up and running. The pre-defined set contains one explicit messaging

connection and allows several different I/O connections including:

• bit strobed command/response

• polled command/response

• change of state

•cyclic

A.1.6 DeviceNet Features

DeviceNet's features include:

1. Low cost.

2. High speed. DeviceNet supports 3 baud rates: 125 kbps, 250 kbps, and 500 kbps. This

meets 95% of typical industrial requirements.

3. Reliability. DeviceNet uses the well proven CAN protocol with application layers that

have undergone strict conformance testing to ensure reliability.

4. Support of up to 64 active nodes.

5. Easy installation.

6. Removal and replacement of devices from the network under power.

7. 0 to 8 byte data packets.

8. Linear (trunk line/drop line) bus topology, with power and signal on the same network

cable.

A.1.7 Maximum Cable Lengths for DeviceNet

DeviceNet defines the maximum cable lengths (trunk and drop cables) to ensure the

propagation of the transmitted message falls within the acceptable limits. The upper

boundaries of the trunk cable and drop cable length are shown below.

A–4 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

DEVICENET OVERVIEW CHAPTER A:

A.1.8 DeviceNet Specification Highlights

Description:

The DeviceNet specification defines a network communication system for transferring

data between elements of an industrial control and automation system. The specification

is divided into two volumes and defines the following elements:

Volume 1:

• DeviceNet communication protocol and application (Layer 7: Application layer)

• CAN and its use in DeviceNet (Layer 2: Data Link Layer)

• DeviceNet physical layer and media (Layer 1: Physical Layer)

•Volume 2:

• Device profiles for interoperability and interchangeability among like products

CAN defines the syntax or form of the data transfer. The DeviceNet application layer

defines the semantics or meaning of the data transferred

Communication Protocol and Application:

Standard or application specific objects are combined together into Device Profiles by the

applications using DeviceNet. The Device Profile defines the device as viewed from the

network: DeviceNet specifications contains a library of objects and Device Profiles. ODVA

coordinates the work of industry experts in the development of both new Object and

Device Profile specifications.

DeviceNet supports strobed, polled, cyclic, change-of-state, and application-triggered

data transfer. The user can choose master/ slave, multi-master and peer-to-peer, or a

combination depending on device capability and application requirements. The choice of

data transfer can significantly speed up system response time. One popular application for

DeviceNet is to use a standard, predefined set of connections that allow devices to

operate in a master/slave connection set.

Connections:

The DeviceNet communication protocol is based on the idea of connections. Connections

must be established with a device in order to exchange information with that device.

CHAPTER A: DEVICENET OVERVIEW

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–5

The Object Model:

The Object Model provides a template for organizing and implementing the Attributes,

Services and Behaviors of the components of a DeviceNet product.

The model provides an addressing scheme for each Attribute consisting of four

components i.e Node Address, Object Class Identifier, Instance Number, and Attribute

Number. This four-level address is used in conjunction with an Explicit Messaging

Connection to transfer the data from one place to another on a DeviceNet network.

Device Profiles:

To promote the interchangeability of alike devices, a “Device Profile” of main device

classes for industrial automation have to be specified that secure the same basic

(“standard”) behavior of devices of different manufacturers.

Beside a description of the device functionality, the device model must also provide a

description of the device identity, version number, status, diagnostic information,

communication facilities, and configuration parameters.

A DeviceNet device profile must contain the following information:

• An object model for the device type.

• The I/O data format for the device type.

• Configuration data and the public interfaces to that data. This information is

contained in an Electronic Data Sheet (EDS file) included with the device.

The DeviceNet specification defines an Electronic Data Sheet which is a simple file format

that allows product-specific information to be made available by vendors for all other

vendors. This makes possible user-friendly configuration tools that can be easily updated

without having to constantly revise the configuration software tool.

A–10 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

LM10 AND GE FANUC 90-30 WITH DEVICENET™ CHAPTER A:

A.2.6 COS (Change of State) Input/Output Connection

With change of state, a device will produce data only when it changes state.

The Change of State Input/Output (COS I/O) connection is primarily used for alarm and

status notification. In the LM10, COS data is described in Object Class 4, instance 54.

Use the following procedure to establish the COS I/O connection between the LM10 and

PLC.

ZUnder the Connection 2 tab in the DN9030 master properties,

select COS.

ZEnter Input Resources size as 1 byte (since the LM10 has 1 status

byte).

Note that we have established Connection 1 as a Polled Input/

Output connection.

ZTo set the slave COS, go to Connection 2 under Mac ID1 Properties

(GE LM10, Slave ID:1) and select COS under the Connection 2 tab.

ZSelect the default input size of 1 bytes and the connection type as

“Status”.

ZDouble-click the added slave device to view the data area for

Connection 2.

ZOpen the Reference View Table and add address %I00089.

ZTo interpret the 1 byte of status information for address %I00097,

refer to Object Class 4, Instance 54 in Assembly Object on page 5–

48.

A.2.7 Cyclic Input/Output Connection

The Cyclic Input/Output Connection option reduces unnecessary traffic and packet

processing. Instead of a slave device scanned dozens of time each second, it can be set to

report data on a regular basis consistent with the rate of change it can detect.

Basically, the same data is available in both COS and Cyclic connections. The primary

difference is in the way the data is reported to the DeviceNet™ master. The Cyclic I/O

connection is also used for alarm and status notification. In the LM10 system, cyclic data is

described in Object Class 4, Instance 54.

Use the following procedure to establish the Cyclic Input/Output connection between the

LM10 and PLC.

ZUnder the Connection 2 tab in the DN9030 master properties,

select COS and enter Input Resources size as 1 byte (since the LM10

has 1 status byte).

Note that we have established Connection 1 as a Polled Input/

Output connection.

ZTo set the slave COS, go to Connection 2 under Mac ID1 Properties

(GE LM10, Slave ID:1) and select COS under the Connection 2 tab.

ZSelect the default input size of 1 bytes and the connection type as

“Status”.

CHAPTER A: LM10 AND GE FANUC 90-30 WITH DEVICENET™

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–11

ZDouble-click the added slave device to view the data area for

Connection 2.

ZOpen the Reference View Table and add address %I00089.

ZTo interpret the 1 byte of status information for address %I00097,

refer to Object Class 4, Instance 54 in Assembly Object on page 5–

48.

A.2.8 Explicit Messaging

Description:

Explicit messaging provides multi-purpose, point-to-point communication paths between

two devices. It typically provides request/response-oriented network communication used

to perform node configuration and problem diagnosis.

In the GE Multilin LM10 Motor Protection System. explicit messaging is used for

configuration and monitoring.

Use the following procedure to set the network for explicit messaging:

ZFor the master side: In the Network Setting > DN9030 Master

Properties menu, disable connections 1 and 2 by selecting Enable

Explicit Connection.

ZSet the Message Request Size and Message Response Size to 20

bytes.

ZFor the slave side: In the Network Setting > Disable Connection 1

& 2 window, select Explicit Message Size set the value as 20 bytes.

ZConnect the PLC and download the hardware logic.

The configuration should be shown as = EQ.

ZObserve the DeviceNet master module LEDs.

All three LEDs for NET POWER, MOD STATUS, and NET STATUS

should turn solid green. Refer to LEDs on page 3–19 to interpret the

device LED status.

Explicit messaging between the DeviceNet master module and LM10 slave takes place

using COMMREQ ladder instructions.

A communication request begins when a COMMREQ ladder instruction is activated in the

PLC application program. The CPU sends the COMMREQ to the DeviceNet™ master module

in the PLC system. The module receives the command and performs the requested

function.

Monitoring Data:

The ladder logic for monitoring data from the GE LM10 Motor Protection System using

COMMREQ is shown in Ladder Logic for Data Monitoring on page A–13. The ladder logic is

configured as follows:

• Rung 1 and 2 have a timer (thousands), as well as set and reset coils, which toggle

the T1 contact after the timer PV value overflows. With the values shown, the T1

contact will toggle every five (5) seconds.

A–12 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

LM10 AND GE FANUC 90-30 WITH DEVICENET™ CHAPTER A:

• Rung 3 has a Block Move word, 3 blocks.

• Rung 4 has the COMMREQ ladder instruction.

Refer to Chapter 5: Communications for a complete description of each word.

In the ladder below, the Trip Class is read from the slave (LM10 device) MAC ID 1. Some key

word settings to obtain the LM10 Trip Class from Slave 1 are shown below:

• Word 11: Slave MAC ID setting (for example, 1)

• Word 13: Get Attribute (for example, 16#0E to read)

• Word 14: Object Class to which the Request is directed (for example, 16#64)

• Word 15: Instance of Object Class (for example, 1)

• Word 17: Attribute (for example, 16#2F00)

To get parameters under the access type history, Word 13 will be 16#32.

To read the operating voltage, change following words:

• Word 13: 16#32

• Word 17: 16#4500

To view the parameters in a Reference View Table, create a new Reference Table then add

addresses %R00250 and %R00256. The control voltage will be displayed in address

%R00256. Change the display format to unsigned decimal.

To view the slave number of slaves connected to master card, add address %I00001 to the

new reference table. Now, address %I00002 will read “1”, since the LM10 is connected to

the master as slave 1 (MAC ID 1).

Also in the Reference View Table, add the input register %I00xx and output register

%Q000xx for Connection 1 and Connection 2, respectively.

A.3 LM10 and Allen-Bradley SLC500 via DeviceNet™

A.3.1 Description

This section describes DeviceNet communications between the Allen-Bradley SLC500 PLC

card with the GE Multilin LM10 Motor Protection System.

The application example shows how to establish communications between Allen-Bradley

SLC500 PLC (1747-SDN DeviceNet Scanner) card with the LM10 via Polled I/O Messaging,

COS I/O Messaging, and Explicit Messaging.

A.3.2 System Setup

The hardware for the setup example is indicated below:

• PLC: Allen-Bradley SLC500

• CPU: 5/03

• Power Supply: 1746-P1

• DeviceNet Scanner Card: 1747-SDN

• 4 Slot Rack: 1746-A4

• Interface Adapter DeviceNet to RS232: 1770-KFD

• The following Rockwell automation software is used:

•RSLogix 500

• RSNetworx for DeviceNet

•RSLinx

• The following settings are stored in the LM10:

•MAC ID: 09

• Baud Rate: 125

• Pin 21 (control input) connected to 110 V

A.3.3 Initial Steps

Before setting up the DeviceNet network, perform the following steps.

ZStart the RSLinx, RSNetworx, and RSLogix software and load the

corresponding drivers in RSLinx.

ZEstablish Polled I/O, COS I/O, and Explicit Messaging between the

slave LM10 relay and the DeviceNet scanner card 1747-SDN.

The Polled I/O messaging is for control and monitoring. The COS I/O messaging is for

monitoring only. Explicit Messaging is used to retrieve byte wide data (for example, motor

run time in hours, line voltage).

A.3.4 Setting Up the DeviceNet Network

Set up the DeviceNet network as follows:

A–18 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ CHAPTER A:

ZOnce the DeviceNet connection (consisting of the 1747-SDN

Scanner card, 1770-KFD, and LM10 relay) is complete, click the

Online icon and upload the network.

Scanning for the Nodes on the Network will start. Using the EDS Wizard, add the LM10

to the hardware list in RSNetworx. A sample screen of RSNetworx with 3 nodes is

shown below.

• LM10 Motor Protection System: MAC ID 09

• 1770-KFD: MAC ID 62

• 1747SDN Scanner Card: MAC ID 63

FIGURE A–5: Example RSNetworx Screen

A.3.5 Changing the Mode of Operation

Use the following procedure to change the mode of operation.

ZIn RSLogix 500 open the Force File O0 Output.

CHAPTER A: LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–19

FIGURE A–6: Sample Force File

ZTo place the 1747-SDN scanner in Run Mode, toggle the bit O:1/0 to

1 in the O0-output force file.

The CPU will change to the Run state.

When the scanner is in Run mode and the network is healthy, the node number of the

scanner is displayed on the 7-segment indicator on the module. In this case, “63” will be

displayed.

ZToggle the O:1/0 to 0 in the O0-output force file to place/force the

Scanner to Idle mode.

The scanner will also change to Idle mode when CPU mode is

changed to Prog (programming).

When the scanner is in Idle mode, the 7-segment indicator will flash code “80” and the NS

(Network Status) LED indicator on the LM10 changes to flashing green, indicating Online,

Not Connected.

If the Run1 contactor is switched on via O:1/16, then Run1 will drop/turn off when the

scanner changes to Idle mode. The Run1 contactor will pickup again (ON) when the

scanner goes from Idle to Run mode.

A.3.6 Configuring the Slave Device

Use the following procedure to configure the slave device.

ZDouble-click on the scanner icon in RSNetworx.

This will display a configuration screen related to 1747-SDN

scanner (see below).

FIGURE A–7: Scanner Module Scanlist

ZClick on Scanlist tab.

The LM10 will be shown under Available Devices.

ZClick the right arrow to move under 'scanlist'. Double-click on

LM10-1 icon to edit the input/output parameters.

ZSelect Polled and add 1 byte for the Input Size and Output Size.

After adding the input/output parameters, you will be prompted for

downloading to node 9

A.3.7 Control and Monitoring of the LM10

Polling I/O messaging is for control and monitoring of LM10 relay parameters.

CHAPTER A: LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–21

ZIn RSLogix 500, open the O0-Output and I1-Input force files.

FIGURE A–8: Input Force File

ZTo turn on the Run1 contactor, toggle the O:1/16 bit to 1. To turn off

Run1, set this bit to 0.

The status of the Run1 contactor is indicated by the I:1.1/18 bit.

The remote (DeviceNet) control is indicated by the I:1.1/21 bit.

The COS I/O messaging data is available in the I1-Input file, bits I:1.1/24 and onwards.

A.3.8 Explicit Messaging with the LM10 Relay

Explicit messages are stored in the data table of the SLC processor in hexadecimal format.

An M0 copy instruction is used to send the message to the 1747-SDN-scanner module. The

scanner module takes the data and formats it into the proper protocol for transmission on

the DeviceNet network. The destination device (node) receives the message, takes the

appropriate action depending upon the type of command, and formats a reply message

for transmission on the network. The scanner module receives the message that contains

information on the success or failure of the command. The SLC processor uses an M1 copy

instruction to get the message response information from the scanner module. The status

information is placed in the SLC processor data table.

The discussion of Explicit Messaging will be limited to only the elements necessary to allow

this application to function and those that are necessary to provide basic understanding of

the application logic.

Explicit Messaging uses Class, Instance, and Attribute data to build its message structure.

Upon completion of a successful transaction, the logic automatically increments the TXID#

and is ready for the next transaction. Also, the Status data received will be reflected in

Status Word I:s.0 Bit-15. A “1” will be shown for successful message completion. Refer to

the table below for all Status codes as provided by ODVA specification.

A–22 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ CHAPTER A:

A.3.9 Data Table Layout

The data table layout is shown below.

Note that X will be any number set in the data file.

The TXID high byte is used for message tracking and is incremented and checked by ladder

logic. The Command low byte is defined as follows:

• 1 = Execute the block

• 2 = Clear response buffer (1747-SDN only)

• The Port high byte is defined as follows:

• 0 = Channel A

• 1 = Channel B

The Port byte is always “0” for the 1747-SDN.

The Size low byte represents the number of bytes in the transaction body. Essentially, this

is the number of bytes following the MAC ID field.

The Service high byte is defined as follows:

Table A–3: Status Codes Provided by ODVA Specification

Status Data Definition

0 Transaction Block Empty

1 Transaction successful

2 Transaction in progress

3 Slave not in scan list

4 Slave offline

5 DeviceNet port disabled

6 Transaction TXID unknown

7 Unused

8 Invalid command

9 Scanner out of buffers

10 Other transaction in progress

11 Could not connect to slave device

12 Response data too large for block

• 10 (hex), 16 (decimal) = Set Attribute Single (write a single parameter)

• 32 (hex), 50 (decimal) = Get Attribute Multiple (read multiple parameters)

The MAC ID low byte is destination code 09.

The transaction body consists of the Class, Instance, Attribute, and Data bytes.

A.3.10 Ladder Logic

This discussion refers to the Ladder Logic diagrams shown on the following pages.

1. Rung 0000 to Rung 0004 are used to toggle the Bit B4/0 every 1 second; this is the

input to BSL (Bit Shift Left).

2. For every 1 second toggle of B4/0, left-shift the N9:0 register.

3. The bits in the N9:0 register are used to enable Rungs 0007 to 0012.

4. Rung 0006 is used to reload the N9:0 register after overflow.

5. The COP function is used to copy the contains of the M1 file to a specific N register and

transfer the values to the M0 file.
