Digital Output Triggering Signals

    Last Modified: February 26, 2018

    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 cRIO 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 C Series analog modules can supply an analog trigger. For more information, refer to the documentation included with your C Series module(s).

    Refer to the DO Start Trigger Signal and DO Pause Trigger Signal sections for more information about the digital output trigger signals.
