Malfunction (Failure):
Due to a malfunction in the instrument, a fault signal is output.
This status message is always active. It cannot be deactivated by the
user.
Function check:
The instrument is being worked on, the measured value is temporarily
invalid (for example during simulation).
This status message is inactive by default.
Out of specification:
The measured value is unreliable because an instrument specification
was exceeded (e.g. electronics temperature).
This status message is inactive by default.
Maintenance required:
Due to external influences, the instrument function is limited. The
measurement is affected, but the measured value is still valid. Plan in
maintenance for the instrument because a failure is expected in the
near future (e.g. due to buildup).
This status message is inactive by default.
