Hi there.

I am after a bit of guidance on connecting a Mitsy Q03UDECPU ( on board ethernet) to a Modbus TCP slave. I am using GX Works2.

The device I am connecting to does not warrant the cost of buying a QJ71MT91 module, but would like to understand the protocol required to decipher the data from the device.

I have the modbus tables for the data 0x01, 0x02, 0x03 and 0x04, but unsure how to read this in the plc.

Appreciate any advice.
