Digital Input 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.

Three triggers are available: Start Trigger, Reference Trigger, and Pause Trigger. An analog or digital trigger can initiate these three trigger actions. sbRIO I/O parallel digital input modules can be used in any controller slot to supply a digital trigger.
