System and process error messages

General notes
The measuring device always assigns system and process errors which occur to two
types of error messages, resulting in different weightings.
Error message type "Fault message":
x If this message occurs, measuring operation is immediately interrupted or stopped!
x Display on the PROFIBUS o Fault messages are relayed to downstream function
blocks or higher-level process control systems with the status "BAD" of the
corresponding process variable.
x The fault messages can be displayed in the automation system by means of the
manufacturer-specific diagnosis message.
x Local display o A lightning symbol ($) flashes on the display.
Error message type "Notice message":
x Normal measuring operation continues despite this message!
x Display on the PROFIBUS o Notice messages are relayed to downstream function
blocks or higher-level process control systems with the status "UNCERTAIN" of the
corresponding process variable.
x The fault messages can be displayed in the automation system by means of the
manufacturer-specific diagnosis message.
x Local display o An exclamation mark (!) flashes on the display.
Serious system errors, e.g. electronic module defects, are always categorised and
displayed as "Fault messages" by the measuring device. On the other hand, the
measuring system interprets simulations and positive zero return as "Notice messages".
Error messages in the configuration program (Class 2 master) o see table
In Prosonic Flow 93, 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.
