Hi, It's my first time operating in Codesys 2.3, but I have done a good amount of Codesys programming, so I'm a little familiar. I haven't done a lot of RTU, but a lot of Modbus TCP. I don't have the PLC in my reach at the moment, but I'm trying to be a little ahead. We're adding the 750-652 module to read energy from a flowmeter over RTU. There will only be 1 slave. I attached pictures of my current hardware, PLC code, the register datasheet from the slave and the only modbus serial library I seem...
