Input Module Features Chapter 3
Independent Point Trigger
An input state change triggering an event is known as an independent
point trigger.
To use this type of trigger, you must enable the Independent Point Trigger
option in the event definition. You set the
EO.Eventxx.IndependentConditionTriggerEn tag to 1.
For all points that participate in the event, choose what
constitutes an event state.
The tag name changes based on the input function. The
following names are available:
• EO.Eventxx.PtxxDataValue - This tag appears for any
point on the module if no counters are used.
• EO.Eventxx.CounterxxValue - The tags begin at point00
and continue based on the number of counters that the
module uses.
• 0 = On to Off state transition
• 1 = Off to On state transition
Choose which edge of the event triggers the event. That is,
if the rising edge, falling edge, or either edge of the event.
Both of the following:
• EO.Eventxx.EventRisingEn
• EO.Eventxx.EventFallingEn
The combination of the tag settings determines which
edge triggers the event:
• Rising edge triggers the event set by
this combination:
– EO.Eventxx.EventRisingEn = 1
– EO.Eventxx.EventFallingEn = 0
• Falling edge triggers the event set by
this combination:
– EO.Eventxx.EventRisingEn = 0
– EO.Eventxx.EventFallingEn = 1
• Falling edge triggers the event set by
this combination:
– EO.Eventxx.EventRisingEn = 1
– EO.Eventxx.EventFallingEn = 1
Latch the event. This task is optional. EO.Eventxx.LatchEn • 0 = Event is not latched.
• 1 = Event is latched.
