I'm testing out modbus TCP/IP for my home brewery, using Wago PFC200 as both slave and master. I'm using Wago library WagoAppPlcModbus.
Holding registers, input registers' and discrete inputs works fine, but when trying to write multiple coils, it doesn't work. Any idea what I'm doing wrong here?
Attached is a screenshot of my code. I tried both using bit mapping and without. If I change to FC05, and write only 1 coil at the time, it works fine. But I want to write all at the same time..
