Parameters

eventNumber: Type: System Int32
The registered IO Event ID to schedule.

scheduleType: Type: Cognex.VisionPro.Comm.Implementation.Internal CogPrioImplEventScheduleTypeConstants
An enum which controls which type of scheduling to use (i.e. encoder based, or time based scheduling).

scheduleValue: Type: System Int64
A value which controls when the event is scheduled to occur (i.e. number of encoder ticks, or a particular time stamp) depending on the scheduleType.

scheduledUserDataTag: Type: System Int32
A return value which can be used to identify a particular scheduled event instance from the HostNotification event.

scheduledEventInstanceTag: Type: System Int32
A return value which can be used to identify and cancel the instance of the scheduled event.

state: Type: Cognex.VisionPro.Comm CogPrioState
Returns the state of the comm card immediately after the event was scheduled. The I/O state includes the timestamp and encoder count. These values can be useful when trying to determine if the event was scheduled "in time".
