Hi,
I am communicating to a Wago PLC 750/881 in Modbus TCP/IP. In the profile I use this following register:
{"name":"Proportional","bus_datatype":"14","datatype":"float32","type":"inputregister","address":13535,"writable":"true"}
I can read value of the PLC but when I try to write to PLC nothing happen. I am thinking about "inputregister" which is FC04 code.
Probably I have to write to Wago using FC06 code but in the profile which type I have to use?
Thanks.
