Hello! In my configuration, several frequency converters are connected to port number 1, and a Weintek panel is connected to port number 2. Both are Modbus RTU. Please tell me why, after physically disconnecting the frequency converter from the RS485 network, the M172 controller continues to display on the Weintek panel the current and frequency that were at the time of disconnection? Thanks!
