Object ExtAlarmAnalog

An extension of the PmData data item for the connection to the PmAlarmEvent obejct for alarming the overruning the defined limits of the analog value.

Two upper and two lower limit values exceeding can be alarmed using this data extension. The first (high/low) limit is usually called the "technological limit", the second is called "device limit". Each limit watching can be activated separately, but there is in fact no sense to enable the second limit without enabling the first.
