LM10 Motor Protection System
Chapter 1: Introduction
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).

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
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.

2.1.1 DeviceNet
The LM10 has one micro-style (Brad Harrison style) connector that allows the purchase of
pre-built cables for attachment to the unit and the ability to daisy chain from one unit to
the next. These connectors meet all DeviceNet physical layer requirements.
FIGURE 2–1: LM10 DeviceNet Pinout
2.1.2 RS232 Port
The RS232 configuration port uses a standard RJ11 connector to interface with the
programming and display unit (PDU) or with a computer. Both communication and power
will be provided to the PDU through this connection. Standard RS232 levels are used for the
communications.

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
setting the trip class).
The LM10 monitors average current of the three phases over time to determine the motor
condition.

OVERCURRENT FAULT CONDITIONS
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
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.

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
•
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,
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
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
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:
Δ = phase current – average current
(EQ 4.1)
The next formula uses the largest Δ of the three phases.
unbalance level = (Δ ⁄ FLA) × 100%
(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.

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:
watts = 1.732 × average current × voltage × power factor
(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.

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.

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

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
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.

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.

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.

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.

Appendix A
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.

DEVICENET OVERVIEW
CHAPTERA:
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
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.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
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.

CHAPTERA:
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.
Z Under the Connection 2 tab in the DN9030 master properties,
select COS.
Z Enter Input Resources size as 1 byte (since the LM10 has 1 status
byte).

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.
Z Under 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.
Z To 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.
Z Select the default input size of 1 bytes and the connection type as

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:
Z For the master side: In the Network Setting > DN9030 Master
Properties menu, disable connections 1 and 2 by selecting Enable
Explicit Connection.
Z Set the Message Request Size and Message Response Size to 20
bytes.
Z For the slave side: In the Network Setting > Disable Connection 1
& 2 window, select Explicit Message Size set the value as 20 bytes.
Z Connect the PLC and download the hardware logic.
The configuration should be shown as = EQ.
Z Observe the DeviceNet master module LEDs.
All three LEDs for NET POWER, MOD STATUS, and NET STATUS
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
configured as follows:
•
Rung 1 and 2 have a timer (thousands), as well as set and reset coils, which toggle

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.
