Diagnostic information via communication interface
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 adopt 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 several diagnostic events are pending at the same time, only the diagnostic message
with the highest priority is displayed. 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.
