NOTICE
Status signals and diagnostic behavior can be configured manually for certain
diagnostic events. If a diagnostic event occurs, however, it is not guaranteed that the
measured values are valid for the event and comply with the process for the status
signals S and M and the diagnostic behavior: 'Warning' and Disabled'.
