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). LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–1 OVERVIEW 1.2 CHAPTER 1: INTRODUCTION 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 deenergize, 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. 1–2 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 1: INTRODUCTION 1.2.4 OVERVIEW 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. 1.2.5 Block Diagram A single line diagram for the LM10 Motor Protection System is shown below. FIGURE 1–1: Functional Block Diagram LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–3 FEATURES 1.3 CHAPTER 1: INTRODUCTION 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. LED State • No power Green Device operational Red Unrecoverable fault Network status (NS): This two-colored LED is used for the DeviceNet network status. Its function is defined in the DeviceNet specification. LED State 1.3.3 Description Off Description Off No power / not online Flashing green Online, not connected Green Link OK, online, connected Flashing red Connection timeout Red Critical link failure • 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. 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. • 1–4 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 1: INTRODUCTION FEATURES • 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. Baud Rate 125 kbps DIP Switch Position down - down 250 kbps up - down 500 kbps up - up 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. LEDS Display One green LED power indicator and a flashing red trip LED to indicate over/undercurrent, current unbalance, ground fault, under/overvoltage, and trip command. Liquid crystal display: four lines of 16 characters per line. Status The status sub-menu can display current, motor status, Run 1 and Run 2 data, faults, MAC ID, baud rate, and overload class. CONFIG The relay parameters are programmed via the CONFIG button. The CONFIG sub-menu is similar to the status menu, and allows the user to change relay parameters: CT ratio, PT ratio, fault settings, and time delays. Reset The relay can be reset from the PDU, pushbutton, or the LAN. History Mounting Flexibility Displays the last ten (10) trip records. The conditions at the time of fault are displayed and can be scrolled through using the UP/DOWN arrow keys. The relay can be attached to the PDU without hardware to facilitate door mounting. 849713A3.CDR FIGURE 1–2: LM10 Features LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–5 ORDERING 1.4 CHAPTER 1: INTRODUCTION Ordering 1.4.1 Order Codes The order codes for the LM10 Motor Protection System are shown below.

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 3: INTERFACE 3.3 ENERVISTA LM10 SOFTWARE EnerVista LM10 Software 3.3.1 Description The EnerVista LM10 software is intended as an interface to the GE Multilin LM10 Motor Protection System. It has all the capabilities of the GE Multilin LM10 Motor Protection System, although some of the operations may differ slightly. The major difference is configuration parameters are not directly changed from the PDU screen, they must be downloaded after modifying. Also data values can be entered directly with the keyboard digits. FIGURE 3–1: Main software screen 3.3.2 Functional Details The EnerVista LM10 software has three menus: File, Communication and Help. The File menu has following submenu items: • New: Loads the memory with default values for the LM10 configuration parameters. • Load: Loads the selected file and restores the LM10 configuration and communication parameters from the file. • Save: Saves the LM10 configuration and communication parameters to the selected or entered file. • Exit: Closes the program. The Communication menu has the following submenu items: LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 3–23 ENERVISTA LM10 SOFTWARE CHAPTER 3: INTERFACE • Download: Sends the configuration parameters from memory to the connected LM10. Note that you must be logged into the LM10 as a configurator to download configuration parameters. • Upload: Gets the configuration parameters from the connected LM10 and saves them in memory. • Port: Shows the available communications ports. The current selected COM port is indicated by a check mark. The green power LED indicates that communication is currently established with the LM10. The Help menu has following submenu items: • Manual: Opens the enerVista LM10 setup software help file. • About: Displays the enerVista LM10 setup software version and information. The EnerVista LM10 software uses hot keys for the following that equate to a mouse click on the PDU keys.

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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–25 OVERCURRENT FAULT CONDITIONS CHAPTER 4: FUNCTIONALITY FIGURE 4–1: Cold Motor Trip Curves FIGURE 4–2: Hot Motor Trip Curves 4–26 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 4: FUNCTIONALITY 4.1.2 OVERCURRENT FAULT CONDITIONS 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 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–27 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. 4–28 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 4: FUNCTIONALITY 4.2 CONFIGURATION SETTINGS Configuration Settings 4.2.1 Overview An overview of the LM10 programmable parameters is shown below.

The settings for Run 2 setup are identical. 4–32 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 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, 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: 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–33 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. 4.2.7 Time Delays PATH: Configuration ØØØØØ Time Delays Configuration Time Delays Other Settings Aux Rly Faults Time Delays AuxSns1 .4 Range: 0.1 to 25.0 s in steps of 0.1 or Disabled Time Delays AuxSns2 .4 Range: 0.1 to 25.0 s in steps of 0.1 or Disabled Time Delays Run1-Run2 0 Range: 0 to 600 s in steps of 1 (0 to 180 s in steps of 1 for revisions 1.40 and lower) Time Delays Run2-Run1 0 Range: 0 to 600 s in steps of 1 (0 to 180 s in steps of 1 for revisions 1.40 and lower) 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. 4.2.8 Other Settings PATH: Configuration ØØØØØØ Other Settings Configuration Other Settings Aux Rly Faults Passcode,login 4–34 Other Settings U/O Volt En off Range: On, off.

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 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–35 CONFIGURATION SETTINGS CHAPTER 4: FUNCTIONALITY 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. • 4.2.9 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.

Without a passcode, the display will only indicate configuration parameters, current operating conditions, and history records. This security feature reduces the likelihood of inadvertent changes. To make any configuration changes, the login level must be set to “Config”. The "User" login simply allows viewing of history and current status but will not accept changes to any parameters. As an extra security feature, the login level can automatically be set to "User" via DeviceNet communications. Refer to Assembly Object, Class Code 4, Instance 100 for more information. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–37 CONFIGURATION SETTINGS CHAPTER 4: FUNCTIONALITY Entering a passcode at the Pass Code, Login screen will change the login indicated by an asterisk at the end of the line. The default passcode is “0”. You must be logged in as “Config” to be able to change the passcode. The green power LED will flash while logged in as configurator. The unit will stop any run relay when in configuration mode. The LM10 must be returned to user mode before beginning normal operations. Once the passcode is changed, the PDU will retain it in memory and will automatically login when the CONFIG button is held/pressed upon plugging in the RJ11 connector or on power up. This is handy when using a hand held PDU for multiple relay program changes. 4.2.11 Run Operations PATH: Configuration ØØØØØØØØØ Run Operations Configuration Run Operations Factory default Run Operations Run 1 Range: Run 1, Run 2, Stop Input terminal 21 selects how the run command is controlled.

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.

Byte LL Range: 0 to 99 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 5–61 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. 5–62 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER 5: COMMUNICATIONS 5.2 SERIAL PORT Serial Port 5.2.1 Description This is a standard RS232 port to handle the serial messages. It has a fixed port settings of 19200, 8, N, 1. The PDU uses this port. The protocol for request and response of data is a fixed 8-byte packet. It will always start with SOH and end with a simple checksum (~sum + 1). The packets will include all the functionality found in the DeviceNet Extension object. The data is in ‘big endian’ format here (big end first: MSB-LSB).

LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 6–67 WARRANTY 6–68 CHAPTER 6: MISCELLANEOUS LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL GE Consumer & Industrial Multilin LM10 Motor Protection System 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–1 DEVICENET OVERVIEW A.1.2 CHAPTER A: 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. A–2 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: A.1.4 DEVICENET OVERVIEW 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: A.1.6 • bit strobed command/response • polled command/response • change of state • cyclic DeviceNet Features DeviceNet's features include: A.1.7 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. 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.

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. A–4 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–5 LM10 AND GE FANUC 90-30 WITH DEVICENET™ A.2 CHAPTER A: LM10 and GE Fanuc 90-30 with DeviceNet™ A.2.1 Overview This section describes an example communications setup between the LM10 Motor Protection System and the GE Fanuc 90-30 PLC via the DeviceNet protocol. • Explicit Messaging: for configuration and monitoring. • All the values mentioned in DeviceNet™ object model (voltage, current, power factor, trip class, FLA settings, etc.) can be monitored. • Polling Input/Output Connection: commands to the slave device and status from the slave device. • Data for assemblies #5 and #54. With polling, the Run1 and Run 2 contactors can be controlled. Note that only one relay output can be energized a time. • COS (Change of State) and Cyclic Input/Output Connection: for alarm/event notifications Essentially, the COS/Cyclic connection is intended for monitoring the status of the Run1 and Run2 contactors. A.2.2 GE Fanuc 90-30 PLC Hardware The hardware for the setup example is indicated below: • Main Rack (Base 10 Slot or Base 5 Slot IC693CHS391/7) • Power Supply (IC693PWR XXX) • CPU (IC693CPU XXX) except CPU321 & CPU340 • DeviceNet Master Module (IC693DNM200) • GE Fanuc Software: Cimpilcity ME version 4.00 • DeviceNet Slave Module: GE Multilin LM10 Motor Protection System A.2.3 Network Configuration To connect the LM10 Motor Protection System to the DeviceNet™ master card (IC693DNM200), refer to chapter 2 of the Series 90-30 Programmable Controller manual (publication number GFK-2196). A.2.4 Configuration Procedure Z Complete the basic setup of the rack, power supply, and CPU. Z Add the DeviceNet™ master card (IC693DNM200) to any non-CPU slots 2 to 10. Z Start the GE Fanuc Cimpilcity ME software. Z Add the slave device by right-clicking on the slot containing the DeviceNet™ master card, then click Add Slave. A slave catalog will be displayed. A–6 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND GE FANUC 90-30 WITH DEVICENET™ Z Select GE LM10 under GE Multilin. If the slave is not displayed in the slave catalog, it can be added using the EDS file: Z Click the Have Disk tab in the slave catalog, then open the EDS file for the LM10. We can also add the slave device to the master card from Tool Chest: Z Click the Tool Chest icon in the tool bar. Z Open the drawer of DeviceNet™ devices, select the LM10 slave device under the GE Multilin folder, and drag it onto the DeviceNet™ master card. Z Set the MAC ID on LM10 module equal to the one displayed under the General tab of the Slave Properties window. Z To see the slave properties window, right click on the Slave Device, add it to the Master, and select Network Setting. Z Right-click on Slot 2 where the master card is added. Z Select Network Setting to view the DN9030 master properties. Z Right-click on the LM10 slave device added under the master card for Setting Slave Properties. Z Set the baud rate in DN9030 master properties window equal to baud rate of the LM10 slave device. The LM10 has three (3) baud rate settings: 125, 250, and 500 kbps (125 kbps is the default value). Z Connect the LM10 as per Wiring Diagram on page 2–15. As well, energize terminal pin 21 with 120 V to enable network control. To determine the correct slave input register (%I00xx) and slave output register (%Q00xx), double-click the added slaves under the master and note register 3 for connections 1 and 2. A.2.5 Polling Input/Output Connection Input/output messaging is for time-critical, control-oriented data. It provides a dedicated, special purpose communication path between a producing application and consuming application. The Polling Input/Output Connection will accept 1 byte of command data and returns 1 byte of device status data and 6 bytes of current metering data for poll data group 1 (2 bytes each for phase A, B, and C currents). Z Set the network to polling mode on the master side. Z Under the General tab, set the baud rate equal to the baud rate of the slave device. Z Also, set the Scan Interval and Reconnect Time. Z Select the Polled option under the Connection 1 tab. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–7 LM10 AND GE FANUC 90-30 WITH DEVICENET™ CHAPTER A: Z Enter a value of 7 bytes under input resource and 1 byte under output resource. This is the size of the slave status data and command data. Z Make changes to the slave side settings. Z Under the General tab, set the MAC ID equal to the MAC ID of the slave device. Z Select the Polled option under the Connection 1 tab. The input and output byte size are defined and connection type is Status and Control. Z Place the PLC online and download the hardware and logic to the PLC. Z Observe the DeviceNet™ master module LEDs. All three LEDs for NET POWER, MOD STATUS, and NET STATUS should turn solid green. Z Open a new Reference View Table to monitor and control the slave device, then add address %I00001 (Slave Status Bit Array). Addresses %I00001 to %I00064 will display the status of all slave devices connected to master card. • For example, if the master card detects an LM10 slave device with MAC ID 1, then address %I00002 will read “1”. Similarly, if a slave is connected with MAC ID 2, then address %I00002 will read “2”. Z Start the PLC. The NS LED on the LM10 (MAC ID 1) will turn solid green once the connection is established, and address %I00001 will read “1”. Z Double-click on GE LM10 to view the data areas. For Connection 1 inputs (to master), address %I00081 will display the status. For Connection 1 outputs (from master), address %Q00017 will contain the command for the slave. Z Add the %I00081 and %Q00017 registers to the Reference View Table. The reference view table for the LM10 is shown below. A–8 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND GE FANUC 90-30 WITH DEVICENET™ Phase A values are displayed in %I00105 (223 × 0.1 amps). Phase B values are displayed in %I00121 (212 × 0.1 amps). Phase C values are displayed in %I00137 (218 × 0.1 amps). The Control Byte via Polled I/O is displayed in %Q00017. The Status Byte via COS is displayed in %I00145. The value displayed in register %R0256 is the voltage parameter received by the master from the LM10 via Explicit Messaging. 9. To interpret the bit array displayed in Reference View Table, refer to Assembly Object on page 5–48, in particular instances 54 and 100. Instance 54 is for status and Instance 100 is for control. 10. To control the contactors and reset the LM10 from the fault state: In Reference View Table, address %I00086 will read logic 1, indicating control from the network. To switch on the Run1 contactor, right-click on address %Q00017 and select Turn On. Once the contactor is switched on, address %I00083 will read logic 1, indicating that the Run1 contactor is on. To switch off the Run1 contactor, set address %Q00017 to “0” and address %Q00020 to “1”. This changes address %I00083 to read “0”, indicating that the Run1 relay is off. When the LM10 goes into a fault condition, address %I00081 will toggle to “1”. To reset the LM10 after recovering from the fault state, toggle address %Q00019. Once the LM10 is in the “Ready to Run” state, address %I00081 will set to “0” and the module CUB LED will turn off. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–9 LM10 AND GE FANUC 90-30 WITH DEVICENET™ A.2.6 CHAPTER A: 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). 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 “Status”. Z Double-click the added slave device to view the data area for Connection 2. Z Open the Reference View Table and add address %I00089. Z To 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. 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 “Status”. A–10 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND GE FANUC 90-30 WITH DEVICENET™ Z Double-click the added slave device to view the data area for Connection 2. Z Open the Reference View Table and add address %I00089. Z To 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: 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 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–11 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.

Change the display format to unsigned decimal. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–15 LM10 AND GE FANUC 90-30 WITH DEVICENET™ CHAPTER A: To view the slave number of slaves connected to master card, add address %I00001 to the new reference table. Now, address %I000010 will read “1”, since the LM10 is connected to the master as slave 1 (MAC ID 1). FIGURE A–4: Ladder Logic for Login (User) A–16 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: A.3 LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ 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. Z Start the RSLinx, RSNetworx, and RSLogix software and load the corresponding drivers in RSLinx. Z Establish 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: LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–17 LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ CHAPTER A: Z Once 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. Z In RSLogix 500 open the Force File O0 Output. A–18 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ FIGURE A–6: Sample Force File Z To 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. Z Toggle 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. Z Double-click on the scanner icon in RSNetworx. This will display a configuration screen related to 1747-SDN scanner (see below). LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–19 LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ CHAPTER A: FIGURE A–7: Scanner Module Scanlist Z Click on Scanlist tab. The LM10 will be shown under Available Devices. Z Click the right arrow to move under 'scanlist'. Double-click on LM10-1 icon to edit the input/output parameters. Z Select 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. A–20 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ Z In RSLogix 500, open the O0-Output and I1-Input force files. FIGURE A–8: Input Force File Z To 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. LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL A–21 LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ CHAPTER A: Table A–3: Status Codes Provided by ODVA Specification Status Data A.3.9 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 13 Invalid port 14 Invalid size specified 15 Connection bust Data Table Layout The data table layout is shown below. Table A–4: Data Table Layout Data Location High Byte Low Byte N X:0 TXID Command N X:1 Port Size N X:2 Service MAC ID N X:3 Class (high byte) Class (low byte) N X:4 Instance (high byte) Instance (low byte) N X:5 Attribute (high byte) Attribute (low byte) N X:6 Data (high byte) Data (low byte) 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: A–22 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL CHAPTER A: LM10 AND ALLEN-BRADLEY SLC500 VIA DEVICENET™ • 0E (hex), 14 (decimal) = Get Attribute Single (read a single parameter) • 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.
