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.
Trigger Definition
Enter pattern match state If the event is defined to trigger on the rising edge, the event is triggered when a
state change on any participating point results in all point configuration conditions
being met.
In the event definition dialog box, Trigger Event = On input transition to match
pattern.
Leave pattern match state If the event is defined to trigger on the falling edge, the event is triggered when a
state change on any participating point results in all point configuration conditions
no longer being met.
In the event definition dialog box, Trigger Event = On input transition to not match
pattern.
Enter or leave pattern match
state
