Error messages
5.4.1
Type of error
Errors which occur during commissioning or measuring operation are displayed immediately. If two
or more system or process errors occur, the error with the highest priority is the one shown on the
display.
The measuring system distinguishes between two types of error:
•
System errors:
This group comprises all device errors, e.g. communication errors, hardware
•
Process error:
This group includes all application errors e.g. empty pipe, etc.

5.4.2
Error message type
The device always assigns system and process errors to two error message types (
fault
or
notice
message
), with the result that they are evaluated differently
81.
Critical system errors, e.g. module defects, are always identified and displayed as "fault messages"
by the measuring device.
Notice message (!)
• The error in question has no effect on the current operation.
• Displayed as
→
exclamation mark (!), error type (S: system error, P: process error)
• FOUNDATION Fieldbus
→
Notice messages are transmitted to downstream function blocks or
higher-level process control systems using the "UNCERTAIN" status of the output value OUT
(AI Block).
Fault message (
$
)
• The error in question interrupts or stops the current operation.
• Displayed as
→
lightning flash (
$
), error type (S: system error, P: process error)
• FOUNDATION Fieldbus
→
Fault messages are transmitted to downstream function blocks or
higher-level process control systems using the "BAD" status of the output value OUT (AI Block).
