MinH - property of the ExtAlarmAnalog object
Description:
Hysteresis value of the lower limits 1 and 2.
Note:
Property access
for read and write.
The default value of this property is defined in the "
Hysteresis for lower limits" configurator of this object.
The hysteresis prevents repeated triggering of the alarm if the value oscilates around the corresponding limit.
There are exactly defined limit values of corresponding
Min1 and
Min2 that trigger the alarm.
The alarm is stopped once the measured value go below the limits
Min1 or
Min2 by the value of defined hysteresis.
It means the limits for alarms to start are
Min2 and
Min1, and for alarms to stop are
Min1+
MinH and
Min2+
MinH.
