Failure: Due to a malfunction in the instrument, a failure message is
outputted.
This status message is always active. It cannot be deactivated by the
user.
Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Out of specification: The measured value is unstable because the
instrument specification is exceeded (e.g. electronics temperature).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Maintenance: 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).
