Good evening guys,

Please, I need help.
This is my first time working with RS485 comm and I dont know what to do.

Please, see attached files.

I have ET200SP with 1512 CPU. I have Weidmuller UR20 device with RS485 module.

I need to communicate with pfeifer device TC400.

Can you give me advice what am I doing wrong or what fb to use?

I am really desperate, because I go through almost all topics.

Thank you,
Dufino
