9.2 System and process error messages
General notes
System and process errors are permanently assigned to two different error message
types and are thus given different priorities:
Error message type “Fault message”:
• This signal will cause the measurement operation to be immediately interrupted or
stopped!
• Presentation on the PROFIBUS → Fault signals will be reported to the next function
block or the control system by setting the status of the corresponding process value
to “BAD”.
• Local display → A blinking lightning bolt (
) will appear.
Error message type “Notice message”:
• The measurement operation will continue as usual in spite of this message!
• Presentation on the PROFIBUS → Notice messages will be reported to the next func-
tion block or the control system by setting the status of the corresponding process
value to “UNCERTAIN”.
• Local display → A blinking exclamation point (!) will appear.
Serious system errors, e.g. a fault in the electronic module, are always evaluated by the
instrument as a “fault signal” and will be displayed! Simulations and the suppression of
the measured value are only reported with a “Notice message”.
Error messages in the configuration program (Class 2 Master)
→ see Table
In the Promag 53 system/process errors are recognised and reported in the Transducer
Block and Analog Input Block. The following table contains a listing of the device status
messages for the Analog Input blocks (PROFIBUS-Profile 3.0) and a description of the
device status messages which may appear on the display (Measured value Q = Meas-
urement Quality).
