I am trying to communicate with PM1200 schneider (with ModbusGateway RS485 to TCP) through ModbusTCP CI867 but failed. It showing code -7004, which showing Slave is responding with exception. I check on the MoxaGateway Traffic Monitor and it is showing Diagnostic (Exception). From the hardware Unit status it is showing Polling retrieval error on Modbus serial slave.
Did tried by using ModScan and it is working but not through CI867.
