34 FSAFE_VALUE Default value for the OUT parameter, if sensor or sensor electronic
fault is detected. The unit of this parameter is the same like the OUT one. Auto 0.0
35 ALARM_HYS Amount the PV must return within the alarm limits before the alarm
condition clears. Alarm Hysteresis is expressed as engineering units
of the PV span. Auto 0.5% of range

43 LO_LO_LIM The setting of the low low alarm in engineering units. Auto -INF
46 This parameter is used in order to show 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. – 0 Unacknowledged

47 This parameter is used in order to show the state of the upper limit of
warnings. This parameter contains the state of the upper limit of a
warning 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 warning. – 0 Unacknowledged HI_ALM

49 This parameter is used in order to show the state of the lower limit of
alarms. This parameter contains the state of the lower limit of an
alarm and the related time stamp. The time stamp expresses the
time the measured variable has been equal or lower than the lower
limit of the alarm. – 0 Unacknowledged LO_LO_
ALM

48 This parameter is used in order to show 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 the measured variable has been equal or lower than the lower
limit of the warning. LO_ALM

Transducer Block in the Analog Input Function Block AI-FB can be
modified. That means that the Transducer and AI-FB will be
disconnected. Auto 0 Simulate_Status

If a specific unit of OUT parameter is not in the code list the user has
the possibility to write the specific text in this parameter. The unit
code is then equal “textual unit definition”. OUT_UNIT_TEXT
