Modbus tcp-ip problem
#8
Last month I have used an Eliwell too, so I am almost sure that registers from 8000 are registers and not coil.
As admin say, you don't have to use 2 variables to read and write a register. I'll try to explain with an example:

{"name": "Temperatura Air Return", "bus_datatype": "9", "datatype": "int16", "type": "register", "address": 16391, "value_multiplier": 0.1, "writable": true},

if in your register 16391 there's the value 200°C, with the thet code you read 20,0°C and when you try to write, for example 30,5°C, in your PLC the homelynk will write 305°C.

Hope I was helpful Wink
