Counters 0 and 1 each have two inputs (source and gate), one output, and
two software registers, which are used to perform different operations.
Counter functionality is built into the DAQ-STC. For more information on
the DAQ-STC, refer to the
Overview.
Counters support two different triggering actions: start and pause. Only
digital triggers can initiate these actions. For more information on digital
triggers, refer to the

Triggering with a Digital Source

Chapter 10, Triggering.
A start trigger begins a finite or continuous pulse generation. When a
continuous generation is initiated, the pulses continue to generate until
you stop the operation in software. The specified number of pulses are
generated for finite generations unless the retriggerable attribute is used.
The retriggerable attribute causes the generation to restart on a subsequent
start trigger.
