I am trying to use Ignition to read data from Carlo-Gavazzi WM14 energy meters using information from their serial protocol documentation. I can’t get it to work properly so I’ve tested my comms using the handy Simply Modbus TCP client 8.0.4.
The registers I want to read start at address 0280h (= 640+1 decimal). When I configure Simply Modbus as shown below I get good readings back from my energy meter.
