This parameter is used in order to set the state of the upper limit of
alarms.
This parameter contains the state of the upper limit of an alarm and
the related time stamp. The time stamp expresses the time the
measured variable has been equal or higher than the upper limit of
the alarm. 38 HI_HI_ALM

This parameter is used in order to set the state of the lower limit of
warnings.
This parameter contains the state of the lower limit of a warning and
the related time stamp. The time stamp expresses the time at which
the measured variable has been equal to or lower than the lower
limit of the warning. 40 LO_ALM

For commissioning and test purposes the input value from the
Transducer Block in the Totalizer Function Block, TOT-FB can be
modified when the hardware simulation jumper is on. That means
that the Transducer and TOT-FB will be disconnected. 52 SIMULATE
