  • Associated product(s)
In the Alarm Logging editor in WinCC, you can insert the "PLC/CPU number" column for messages. However, this is not automatically services by the AS/OS transfer. You have two options for displaying this information in the message

  1. Add the values manually in Alarm Logging
    After an AS/OS transfer in the transfer mode "All" and "With overall reset of the OS", these entries are deleted again.
  2. Configure the values in the Engineering Station in STEP 7
    When configuring the message, you can enter the values in the ES, for example in the "Text6" column (see Fig. 1). After "Transfer AS-OS connection data) the data in this case is displayed in the "Free1" column of the WinCC messages.
