System/process error messages
General notes
The device assigns current system and process errors to two error message types, with the result
that they are evaluated differently:
"Fault message" error message type:
• A message of this type immediately interrupts or stops measurement.
• Presentation on the FOUNDATION Fieldbus
→
Fault messages are transmitted to downstream
function blocks or higher-level process control systems using the "BAD" status of the AI output
parameter OUT.
• Local display
→
A flashing lightning symbol (
$
) is displayed
"Notice message" error message type:
• Measurement continues despite this message.
• Presentation on the FOUNDATION Fieldbus
→
Notice messages are transmitted to downstream
function blocks or higher-level process control systems using the "UNCERTAIN" status of the
AI output parameter OUT.
• Local display
→
A flashing exclamation mark (!) is displayed.
Critical system errors, e.g. defects in the electronics module, are always identified 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 by the measuring system as "notice messages" only.

See Table
In the Promag 55, system and process errors are recognized and reported in the Transducer Blocks.
Such errors are displayed via the following parameters defined in the FOUNDATION Fieldbus
specification:
• BLOCK_ERR
• Transducer Error
In the "Diagnosis" Transducer Block (base index: 1600), detailed causes of errors and device status
messages are displayed by means of the "Diag. - Act.Sys.Condition" parameter (manufacturer-
specific)
