Event Definition
Table 12 describes the event definition parameters that you can configure using the Event
Output tags.
Table 12 - Event Definition Tags
Task Event Output Tag to Change Valid Values
Enable the event. EO.Eventxx.En
0 = Event is disabled
1 = Event is enabled
Determine if an input state change on any
single selected point or a pattern of input
state changes across all selected points
triggers the event.
EO.Eventxx.IndependentConditionTriggerEn
0 = Pattern of input state changes triggers the event
1 = Single input state change triggers the event
Select at least one channel on the module to
participate in the event.
The tag name changes based on the input function. The
following names are available:
• EO.Eventxx.PtxxDataSelect – This tag appears for any
channel that is configured as “Digital Input” or “Digital
Input, Timestamp”.
• EO.Eventxx.CounterxxSelect – This tag appears for any
channel that is configured as “Digital Input, Counter”.
0 = Point does not participate in the event trigger
1 = Point participates in the event trigger
For all channels that participate in the event,
determine 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
channel that is configured as “Digital Input” or “Digital
Input, Timestamp”.
• EO.Eventxx.CounterxxValue – This tag appears for any
channel that is configured as “Digital Input, Counter”.
0 = On to Off state transition
1 = Off to On state transition
Determine which edge of the event triggers
the event. That is, 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:
• This combination triggers the event on a rising edge:
– EO.Eventxx.EventRisingEn = 1
– EO.Eventxx.EventFallingEn = 0
• This combination triggers the event on a falling edge:
– EO.Eventxx.EventRisingEn = 0
– EO.Eventxx.EventFallingEn = 1
• This combination triggers the event on either a rising or
falling edge:
– EO.Eventxx.EventRisingEn = 1
– EO.Eventxx.EventFallingEn = 1
Determines whether to latch the event. EO.Eventxx.LatchEn
0 = Event is not latched
1 = Event is latched
