Digital Output Triggering Signals

A trigger is a signal that causes an action, such as starting or stopping the acquisition of data. When you configure a trigger, you must decide how you want to produce the trigger and the action you want the trigger to cause. The sbRIO controller supports internal software triggering, external digital triggering, analog triggering, and internal time triggering.

Digital output supports two different triggering actions: DO Start Trigger and DO Pause Trigger. A digital or analog trigger can initiate these actions. Any PFI terminal can supply a digital trigger, and some sbRIO I/O analog modules can supply an analog trigger.
