Analog Output Triggering Signals

Version:
    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.

    Analog output supports two different triggering actions: AO Start Trigger and AO Pause Trigger. An analog or digital signal can initiate these actions. C Series parallel digital input modules and the controller’s integrated PFI trigger line can be used in any controller slot to supply a digital trigger. An analog trigger can be supplied by some C Series analog modules.

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