Object ExtAlarmAnalog

An extension of the PmVar variable of the PmaData object for connection to the PmaAlarmGroup object for alarm the overruning the defined limits of the numeric 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 set separately, but there is in fact no sense to enable the second limit without enabling the first.
