Status name Description
NORMAL The communication interface can respond to com-
mands. All defined blocks of the gauge exist.
RUNNING All block instances are initialized and the individual
parameters have their initial or default values.
SELFTESTING In this status, the gauge performs a selftest.
IDLE All blocks defined in the gauge are initialized and the
complete hardware has been tested and found free
of errors. The value defined in the Safe State is out-
put as measured value.
SELFTEST EXCEPTION During the self test, an error has been detected. The
gauge has changed to the SELFTEST EXCEPTION
status. The cause of the error can be found in the
attributes Device Exception Detail Alarm/Warning of
the Device Block. The value defined in the Safe State
is output as measured value.
EXECUTING The gauge functions normally and outputs the meas-
ured value.
ABORT The Device Block is in the ABORT status. The gauge
specific measurement functions are not carried out.
CRITICAL FAULT A device error has occurred. The gauge specific
measurement functions are not carried out. The
value defined in the Safe State is output as meas-
ured value.
There are a number of special commands for bringing the gauge into a status it
does not automatically go to.
