Overview
The example demonstrates the write instance of the digital channels using only one task of DAQmx

Description:
The basic VI would shows how to write a multiple line defined by the user by utilizing the build array function of the LabVIEW

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 Module

You could have also just used a physical channel constant that reads: "Dev1/port0/line7,Dev1/port1/line0:3" and avoided the build array and DAQmx Flatten Channel to String.
