Overview 7.1.1 Modbus The GE Multilin PQM implements a subset of the AEG Modicon Modbus RTU serial Protocol communication standard. Many popular programmable controllers support this protocol directly with a suitable interface card allowing direct connection of the PQM. Although the Modbus protocol is hardware independent, the PQM interface uses 2-wire RS485 and 9-pin RS232 interfaces.
OVERVIEW CHAPTER 7: MODBUS COMMUNICATIONS 7.1.3 Data Format & One data frame of an asynchronous transmission to or from a PQM consists of 1 start bit, 8 Data Rate data bits, and 1 stop bit, resulting in a 10-bit data frame. This is important for high-speed modem transmission, since 11-bit data frames are not supported by Hayes modems at bit rates greater than 300 bps.
CHAPTER 7: MODBUS COMMUNICATIONS OVERVIEW 7.1.5 Error Checking The RTU version of Modbus includes a 2-byte CRC-16 (16-bit cyclic redundancy check) with every transmission. The CRC-16 algorithm essentially treats the entire data stream (data bits only; start, stop and parity are ignored) as one continuous binary number. This number is first shifted left 16 bits and then divided by a characteristic polynomial (11000000000000101B).
OVERVIEW CHAPTER 7: MODBUS COMMUNICATIONS 8. is j = 8? No: go to 5. Yes: go to 9. 9. i+1 --> i 10. is i = N?No: go to 3. Yes: go to 11. 11. A --> CRC 7.1.7 Timing Data packet synchronization is maintained by timing constraints.
CHAPTER 7: MODBUS COMMUNICATIONS MODBUS FUNCTIONS Modbus Functions 7.2.1 The following functions are supported by the PQM: Supported • 03: Read Setpoints and Actual Values Modbus • 04: Read Setpoints and Actual Values Functions • 05: Execute Operation • 06: Store Single Setpoint •...

MODBUS FUNCTIONS CHAPTER 7: MODBUS COMMUNICATIONS 7.2.8 Function Code Modbus Implementation: Preset Multiple Registers 16 – Store PQM Implementation: Store Multiple Setpoints Multiple This function code allows multiple Setpoints to be stored into the PQM memory. Modbus Setpoints "registers" are 16 bit (two byte) values transmitted high order byte first. Thus all PQM setpoints are sent as two bytes.
CHAPTER 7: MODBUS COMMUNICATIONS MODBUS FUNCTIONS 7.2.9 Function Code Some PLCs may not support execution of commands using function code 5 but do support 16 - storing multiple setpoints using function code 16. To perform this operation using function Performing code 16 (10H), a certain sequence of commands must be written at the same time to the Commands PQM.
Page 194
MODBUS FUNCTIONS CHAPTER 7: MODBUS COMMUNICATIONS 7.2.10 Function Code In applications where multiple devices are daisy chained, it may be necessary to 16 - Broadcast synchronize the clocks (date and/or time) in all the devices by sending one command. The Command broadcast command allows such synchronization as shown in an example below.
CHAPTER 7: MODBUS COMMUNICATIONS MODBUS FUNCTIONS 7.2.11 Error When a PQM detects an error other than a CRC error, a response will be sent to the master. Responses The MSbit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128).

DNP 3.0 PROTOCOL CHAPTER 8: DNP COMMUNICATIONS This point is used to reconstruct voltage values from the 1,000ths per-unit quantities given in the other points. Multiply the particular point by this one, and divide by 1000 to get volts. Since some SCADA systems don’t read 32 bit values, you can also multiply the VT ratio and nominal secondary (both of which are 16 bit) in the master in cases where the nominal primary may exceed 32767 volts.

APPENDIX A: APPLICATION NOTES PHASORS IMPLEMENTATION Let k = cos(π/8), k = cos(π/4), k = cos(3π/8); the equations for the real and imaginary components are reduced to: Re g ( ) -- - k – – – – – – –...
TRIGGERED TRACE MEMORY APPENDIX A: APPLICATION NOTES Triggered Trace Memory The Triggered Trace Memory can be used to detect and record system disturbances. The PQM uses a dedicated continuous sampling rate of 16 samples per cycle to record fluctuations in voltage or current as per user defined levels. The PQM calculates the true RMS value of one consecutive cycle, or 16 samples, and compares this value with the user- defined trigger levels to determine if it will record all sampled waveforms.
APPENDIX A: APPLICATION NOTES PULSE OUTPUT APPLICATION Pulse Output Application Up to 4 SPDT Form C output relays are configurable as Pulse Initiators based on energy quantities calculated by the PQM. Variables to consider when using the PQM as a Pulse Initiator are: •...

PULSE OUTPUT APPLICATION APPENDIX A: APPLICATION NOTES match the registration of the end receiver. For example, if the end receiver counts each closure as 100 kWh and each opening as 100 kWh, the PQM Pulse Output Interval should be set to 200 kWh. The PQM Output Relays can be configured as Failsafe or Non-Failsafe to match the normally open/closed configuration of the KY and KZ connections at the end receiver.
APPENDIX A: APPLICATION NOTES DATA LOGGER IMPLEMENTATION Data Logger Implementation The Data Logger allows various user defined parameters to be continually recorded at a user defined rate. The Data Logger uses 64 samples/cycle data. The PQM has allocated 65536 bytes of memory for Data Log storage. The memory structure is partitioned into 512 blocks containing 64 ×...

DATA LOGGER IMPLEMENTATION APPENDIX A: APPLICATION NOTES Data Logs. The Data Logs will place the user-selected parameters into their respective Record structures based upon their respective order in the PQM Memory Map. For example, if Positive kWh, Frequency and Current Unbalance were selected to be measured parameters, they would be placed into the Record structure in the following order: Unbalance2 bytes(16 bit value) Frequency2 bytes(16 bit value)
