Siemens 380022 - PROFIBUS/PROFINET: Configuration of DP master bus has been changed

The PROFIBUS configuration on the DP master was changed during operation, e.g. by downloading a new hardware configuration via STEP 7. As the cycle data may also have changed, operation cannot be continued, and a warm start is required. If the master functionality is within the PLC (as on the 840Di), the PLC will have been stopped for the download, and alarm 2000 (PLC sign-of-life) output Control reaction: Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display.
