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'.

Diagnostic behavior
Alarm Measurement is interrupted. The signal outputs assume the defined alarm
condition. A diagnostic message is generated.
Warning The device continues to measure. A diagnostic message is generated.
Disabled The diagnosis is completely disabled even if the device is not recording a measured
value.
9.4 Diagnostic list
If two or more diagnostics events are pending simultaneously, only the message with the
highest priority is shown. Additional pending diagnostic messages are shown in the
Diagnostic list submenu . The status signal dictates the priority in which the diagnostic
messages are displayed. The following order of priority applies: F, C, S, M. If two or more
diagnostic events with the same status signal are active simultaneously, the numerical
order of the event number dictates the order of priority in which the events are displayed,
e.g.: F042 appears before F044 and before S044.
9.5 Event logbook
Past diagnostic messages that are no longer pending are shown in the Event logbook
