MaxH - property of the ExtAlarmAnalog object
Hysteresis value of the upper limits 1 and 2.
Property access for read and write
. The preset value of this property is defined in the "Hysteresis for upper limits
" configurator of this object.
The hysteresis prevents repeated triggering of alarm if the value oscilates around the corresponding limit.
There are exactly defined limit values of corresponding Max1
that trigger the alarm.
The alarm is triggered once the measured value exceeds the limits Max1
by the value of defined hysteresis.
It means the limits for alarms to start are Max1
, and for alarms to stop are Max1

value = pMe.Pm("/data/#vars/Temperature/#ext/al").MaxH;
value = pMe.Pm("/data/#vars/Temperature").Extension("al").MaxH;
value = pMe.Pm("/data").Item("Temperature").Extension("al").MaxH;
