I have the same problem as Arif
ION Enterprise is a Modbus master, and support Modbus RTU or ASCII.
The software (ION Enterprise), use a 'driver' to know what modbus register have to read and write.
I read the system manual posted by dchartier, but I don't understand so well.
What i need is a modbus register map, with register in decimal format (better for me), for expample, at modbus adress 40963 is stored Current A.
I hope you can help me.
