Parameter Description
l bitMaskAlarm: the bitwise AND operator compares each bit of the bitmask with the tag value
corresponding to that Alarm. If both bits are on, the alarm is set to true. You can specify one or
more bit positions (starting from 0) inside the tag. The Bit position must be given in decimal format;
if more bits are specified, each position must be separated by a ",".
l deviationAlarm: alarm triggered if the percentage of deviation of the tag value from the set point
exceeds a set deviation.
Tag Tag whose value will trigger the alarm when it exceeds the set limits.
The alarm can refer to the value of this tag, or to the state of a bit if bitMaskAlarm has been selected as
trigger.
