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