9. 2 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.
"Fault message" error message type:
• If this message occurs, operation is immediately interrupted or stopped.
• Display on the FOUNDATION Fieldbus  Fault messages are relayed to downstream function
blocks or higher-level process control systems with the status "BAD" of the AI output parameter
OUT.
• Local display  A lightning symbol ($) flashes on the display
"Notice message" error message type:
• Normal operation continues despite this message.
• Display on the FOUNDATION Fieldbus  Notice messages are relayed to downstream function
blocks or higher-level process control systems with the status "UNCERTAIN" of the AI output
parameter OUT.
• Local display  An exclamation mark (!) flashes on the display.
Serious system errors, e.g. electronic module defects, are always categorized and displayed as "Fault
messages" by the measuring device. On the other hand, the measuring system interprets simulations
of the measured value in the Transducer Block "Flow" and positive zero return as "Notice messages".
Error messages in FOUNDATION Fieldbus configuration programs  see Table
In Prowirl 72, system/process errors are recognized and reported in the Transducer Block
"Diagnosis". Such errors are displayed by means of the following parameters specified in the
FOUNDATION Fieldbus Specification:
•BLOCK_ERR
• Transducer Error
In the Transducer Block "Diagnosis", detailed causes of error or device status messages are displayed
via the "Diagnosis - Actual System Condition" parameter (manufacturer-specific)  Table.
Error messages on the local display  See Table

S = System error
$ = Fault message (with an effect on operation)
! = Notice message (without any effect on operation)
001 Device status message (FF):
Critical Failure –
Err. No. 001
Local display:
S: CRITICAL FAIL.
$: # 001
BLOCK_ERR = Device needs

OUT. QUALITY =
BAD
Cause of error:
ROM/RAM error. Error when
accessing the program memory
(ROM) or random access memory
(RAM) of the processor.
Remedy:
Replace the amplifier board.
