Schneider Energy Meters Modbus Readings - s.prathmesh - 23.10.2017
Trying to read data from 7 Schneider Energy Meters (1 no. is EM1200 & 6 nos. are EM6436). EM1200 giving proper readings but none EM6436 not giving the readings. Its readings are changing constantly. This has been tried with resident script and profile as well. Please help. Attached are both meters manuals.

Yes.
Btw, the data reading is proper when communicated with Modscan software.

Looks like -1 is required, try changing read swap parameter in RTU read test.
RE: Schneider Energy Meters Modbus Readings - s.prathmesh - 24.10.2017
RTU read test is successful. But, the data is read different every time it is requested. However, this is not the case in Modscan software.
RE: Schneider Energy Meters Modbus Readings - admin - 24.10.2017
In RTU read test set address to 43914 (frequency) and data type to float32. Then try reading values with different read swap parameters. When you find correct read swap value set it in profile as stated here: http://openrb.com/docs/modbus.htm

Thank you, it worked with n (no swap).
