Using Ignition v8.1.13
I have a child Memory String tag called devStatus
within a UDT. The tag can have values that include Fault
and Unknown
. I want to create Equal Mode alarms for for when the value of devStatus
equals Fault
and Unknown
. It doesn’t seem possible, the setpoint data type is Numeric.
Looking for a work around.
If there were System function to create an alarm I’d add a Value Changed script to devStatus
but that function doesn’t seem to exist.
I suppose I can add a child Expression Integer tag (call it devStatusValue
) and set its value so 1 and 2 for the String values and create alarms in this tag.
Any better ways to do this?
Thank you.
