Function Options Info
Measured value Options (depends on
sensor/data source)
• None
• Totalized flow
• Current
• Temperature
•
PROFIBUS AO 0x
Factory setting
None
Operating mode Selection
• Upper limit
• Lower limit
• Within range
• Out of range
• Rate of change
Factory setting
Upper limit
Type of limit value monitoring:
• Limit value overshoot or undershoot
• Measured value within or outside a range
• Rate of change
Limit value Range of adjustment and
factory setting
Depends on the measured
value
Operating mode = Above limit check or
Below limit check
• The event is triggered if the limit value +
hysteresis is exceeded for the switch-on
duration.
• The event is reset again if the limit value ‐
hysteresis is undershot for the duration of
the switch-off delay at least.
Range lower value Range of adjustment and
factory setting
Depends on the measured
value
Operating mode = In range check or Out of
range check
• The event is triggered if the range lower
value + hysteresis is exceeded for the
switch-on duration.
• The event is reset again if the range upper
value
‐
hysteresis is undershot for the
duration of the switch-off delay at least.
Range upper value
Hysteresis Range of adjustment and
factory setting
Depends on the measured
value
The hysteresis is the difference between the
switch-on point and the switch-off point if
values, which cause the limit switch to pick
up, become closer or move further apart. It is
needed to ensure a stable switching
behavior.
Start delay 0 to 9999 s
Factory setting
0 s
Synonyms: pick-up and drop-out delay
Switch off delay
Delta value Range of adjustment and
factory setting
Depends on the measured
value
Operating mode = Change rate
The event is triggered if the measured value
changes by at least the delta value (both
positive and negative) within the set delta
time. The event is deleted as soon as the rate
of change is lower than the set value and the
auto confirmation time has elapsed.
Delta time 00:01 ... 23:59
Factory setting

Auto confirm 00:01 ... 23:59
