Hello guys, I need some help!

I have 1 inverter (MM430) communication with S7-200 (CPU 224XP) via the USS protocol.

However, I can only control inverter start / stop and change the frequency but can not read parameters from the inverter (such as current, status,...).

I get error codes 01 (drive did not respond). My program test in attachments

Thank you very much!

Best regards
