Communication with EasyLogic PM2200 (by Schneider)

[smarius76 0]

Hi

I try to make a communication between CJ2M (with SCU 32), as master, and two EasyLogic PM2200, as slaves, through a modbus RTU communication.

I use function block specified  in this library  https://www.myomron.com/index.php?article=1245&action=kb  (I Use MRTU_SCU_Master sample) but no response fom the slave.

On Modbus Error code (from function block) appear code 8303 hex.

What I am doing wrong. Can somebody help me?

Thank you

I use CJ2M with SCU32, Modbus RTU, in the sample is CP1L Modbus TCP.

I use function block MRTU_SCU_Master.zip  from this https://www.myomron.com/index.php?action=kb&article=1245
