I have sinamics v20 controlling dosing pump, plc s71200. The connection Is with RS485 to P ,N terminal so I thing is USD or Modbus.No eny faults or errors. When in auto mode the pump didn't start , we thing some change some data in sinamics v20 because they are operating only in manual mode and we know that before it works in auto. So can you advice which parameters to check in sinamics v20 for this time connection. Thanks
