Pattern Match Trigger
When a pattern of input state changes triggers an event, multiple points
participate in the event trigger. To use this type of trigger, you must disable the
Independent Point Trigger option in the event definition. You set the
EO.Eventxx.IndependentConditionTriggerEn tag to 0.
Every point that participates in an event trigger is configured separately.
Depending on the event definition, the collective status of all points triggers
the event. The table describes event triggers.
