The task is to connect the frequency inverter to the CPU via Profibus and obtain the current value from the motor. Through Drive Motion, I was able to connect to the frequency inverter via USS. However, there is a problem with connecting to the CPU - the frequency inverter is not visible in the Profibus DP network. Please advise on how to properly configure the connection.
