So if we find a possibility to e.g. start or stop the S120 via RS232 and the CU unit, we would be able to upgrade our customers to S120, too. Is there anywhere a file which discribes how the communication between the CU310/320 and the RS232 is programmed? cu

Most typical would be Profibus with a CP 5512 Profibus card in the PC. I would agree that the RS232 port shouldonly be used for the AOP30 or commissioning the drive with STARTER if Profibus or Ethernet is not available. For most applied applicationstypical ofSINAMICS S120 the baud rate and bandwidth of RS232 is not sufficient.
