System/process error messages
General notes
The flowmeter assigns current system and process errors to two error message types in accordance
with a predefined algorithm and classifies them accordingly:
Error message type "Fault message":
• A message of this type immediately interrupts or stops measurement.
• Presentation on the FOUNDATION Fieldbus
→
Fault messages are transmitted to subsequent
Function Blocks or higher-level process control systems by means of the status "BAD" of the
AI output parameter OUT (AI Block).
• Local display
→
A flashing lightning symbol (
$
) is displayed
Error message type "Notice message":
• Measurement continues despite this message.
• Presentation on the FOUNDATION Fieldbus
→
Notice messages are transmitted to subsequent
Function Blocks or higher-level process control systems by means of the status "UNCERTAIN" of
the AI output parameter OUT (AI Block).
• Local display
→
A flashing exclamation mark (!) is displayed.
Serious system errors, e.g. module defects, are always classed and displayed as "fault messages" by
the measuring device. Simulations in the "Flow" Transducer Block and positive zero return, on the
other hand, are identified as "notice messages" only.
Error messages in the FF configuration programs
System and process errors are recognized and reported in the Transducer Blocks. Such errors are
displayed via the following parameters specified in the FOUNDATION Fieldbus specification:
• BLOCK_ERR
• Transducer Error
In the "Diagnosis" Transducer Block (base index: 1600), detailed reasons for errors and device status
messages are displayed by means of the "Diag. - Act.Sys.Condition" parameter (manufacturer-
specific)
