An event component has two ports, an Event Source and Resource Source. The Event Source port triggers downstream task components whenever the event fires, and the Resource Source port makes the data from this component available for use by one or more downstream components.
An Event Source port must be connected to a task’s Event Sink (North) port. Each Task component has an Event Sink and an Event Source port.
A Resource Source port that makes data from this component available for use by one or more downstream components. If the event supplies data, connect this port to the Resource Sink port(s) of the Task that receive the data.
