System and process error messages

General notes
The measuring device always assigns system and process errors which occur to two types of error
messages and have different weightings.
Error message type "Fault message":
• If this message occurs, measuring operation is immediately interrupted or stopped!
• Presentation on the PROFIBUS → Fault signals will be reported to the downline 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":
• Normal measuring operation continues despite this message!
• Presentation on the PROFIBUS → Notice messages will be reported to the next function 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. electronic module defects, are always categorised and displayed as "Fault
messages" by the measuring device. Simulations and positive zero return, on the other hand, are
classed as "Notice messages".
Error messages in the configuration program (Class 2 master) → see table
In the Promass 80 system/process errors are recognised and reported in the Transducer and Analog
Input block. The following table contains a list of device status messages pertaining to the Analog
Input blocks (PROFIBUS Profile 3.0) as well as a description of the possible device status messages
on the display (measured value Q = measured value quality).
