Alarms: Activate/deactivate alarmgroup connection

Variables of the selected alarm group are not polled from the driver as long as the alarm group is disconnected, in order to increase the performance of the connection between driver and PLC.

The number of the alarm group and "Connect" or "Disconnect" have to be entered as parameters.

Projecting advice: Create an alarm group bit in the PLC. If this Bit is activated, function Alarm group active is called via the limit administration. So the variables are requested and the according limits in zenon are incited. The bit can be reset in the PLC, and with a limit violation the alarm group is switched inactive again. On program start all limit variables are polled.
