I need to have a PI Alarm point for which i will specify a PI Point as the source tag and generate a alarm whenever the value of the source tag changes. To achieve this there is a condition called Change as per the user manual, but when I set "Change ( )" as the test condition, the alarms are not generated in PI Alarm viewer and it displays "Error" in the Condition column.
The PI Alarm Point is having the following configuration
Source tag = Pi Point (Int32)
Point Type = Digital
Digital Set = pialarm33
action1 = HIGH 2
Auto Ack = no
test1 = Change ( )
With the above settings the PI Alarm point is showing Error in the PI Alarm view window.
