MinH - property of the ExtAlarmAnalog object
Hysteresis value of the lower limits 1 and 2.
Property access for read and write
The preset 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
that trigger the alarm.
The alarm is stopped once the measured value go below the limits Min1
by the value of defined hysteresis.
It means the limits for alarms to start are Min2
, and for alarms to stop are Min1
