Modbus Byte order for PM2100 Series Meter

[dineshkumargowd]

Dear Sir,

I am trying to read holding register from Schneider Easylogic PM2100 series power meter, but unable to read it. I am getting following errors

1. Device 102 “11KV Swst” : error
2018-05-08 09:48:03 Communication session with the Device 102 “11KV Swst”, type: KpModbus, address: 10
Request element group “Voltage group”
Send (8): 0A 03 0B CA 00 02 E7 6A
Receive (5/5): 0A 83 03 70 F3
Device error: [03] ILLEGAL DATA VALUE!

I have tried with multiple byte order like ab cd, dc ba, ba dc, cd ab but in every sequency same errors were occurring. Kindly do needful ASAP

A link to the list of registers PM2100. Perhaps when prompted in RapidScada need to specify the address of the register + 1

Read the document carefully. The voltage starts from the register 3020, it may be necessary to add to the registers +1, that is, to start with 3021

Since there is no register between 3018 and 3020, you get an error from the device

Perhaps when prompted in RapidScada need to specify the address of the register + 1

In addition, you can choose addressing (zero based or 1 based) in the template settings.
