I am trying to read a modbus response for a query send to an inverter over Modbus TCP/IP using the software Docklight.
Query Send in Hex: 15 01 00 00 00 06 01 03 00 BD 00 01 ( Trying to read Register 40188 with offset -1)
Response received: 15 01 00 00 00 05 01 03 02 FF FF
Every query send is responded with same response FF.
Please Help!!
