I have a V90 connect via RS485 with S7-1200. I use standart FB for uss communication for read out current position from V90 (motor with absolute encoder) but it still doesn´t work. USS_PORT gives me status 8188 invalid PZD word. Uss communication is ok because with Sinamics V20 everything works properly. How to set uss comm for V90 ? Thanks for help
