Overview
The example demonstrates how to toggle a Digital Output on and off at a set interval

Description:
This VI uses state machine architecture to toggle a Digital Output on and off at a set interval.  It gets the time when you press Activate, then compares that time to the On Time and Off time.  Once it reaches that time, it will toggle to the other state.  Elapsed time will keep track of how long the Activate button has been pressed.  It will reset when you turn off Activate.

Steps to implement or execute code
To implement this example:

  1. Set the Digital Line of Physical channels to be used
  2. (optional) Set the rest of the parameters as needed
  3. Run the VI
  4. (Optional) Turn on the Highlight Execution to see the flow of the VI

To execute this example:

  1. Install the required software.
  2. Connect the DAQ hardware that supports the Digital Output features
  3. Confirm the connection with the MAX with TestPanel
  4. Open the VI and refer the Implement Steps


Requirements
Software
LabVIEW 2012 or compatible
