Posted 10 Dec 2020 (edited) Hello I have a wago PLC and i try to communicate to a device through RS485 using the module 750-652. I tried using the WagoAppCom library and came up with this code But i always get errors regarding FB_init block. I though the instance would be automatically matched. I still can't see how to resolve this as Wago library documentation is very poor and contains 0 examples. Has anyone else solved serial comms problems?
