Overview
This VI will uses a digital line to move a high line across the digital channels with a trigger.  Only the active line will be high, i.e., the previous line will turn back off after the next line is high.

Description:
The example would covers a very basic use of write the digital line. With that in mind, it would have a caveat of always write without defining the maximum channel of the hardware.

Steps to implement or execute code
To implement this example:
  1. Run the VI
  2. (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 DIO 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
NI-DAQmx 16.0 or compatible

Hardware
cDAQ with C series Digital IO Input Module
