Configuring AlarmActive and AlarmCleared Scripts to Trigger Once Per Event (Above Setpoint Condition)

Ignition

hello,

I'm currently working with a tag in Ignition that has an alarm configured with the condition "Setpoint is 2". This alarm is set to trigger when the tag value goes above the setpoint.

:small_blue_diamond: My Requirement:

  • When the value crosses above the setpoint, the alarmActive script should run once.
  • When the value returns to normal (i.e., below the setpoint), the alarmCleared script should run once.

:small_blue_diamond: The Issue:

If I enable the "Any Change" option:

  • The alarmActive script runs every time the value changes while remaining above the setpoint ā€” which is not desired.
  • The alarmCleared script does not run when the value drops below the setpoint.

If I disable the "Any Change" option:

  • The alarmActive script runs only once when the value first exceeds the setpoint.
  • The alarmCleared script works correctly when the value goes back below the setpoint.
  • However, if the value goes below the setpoint and then rises above it again, the alarmActive script does not run again.

:small_blue_diamond: My Goal:

  • The alarm should activate every time the value crosses above the setpoint.
  • It should clear when the value goes below the setpoint.
  • The alarmActive and alarmCleared scripts should each run once per event, without repeat triggers while the value remains in the same state.

Has anyone successfully configured this behavior? Iā€™d appreciate any guidance or best practices.
