Overview
This code shows how to trigger an analog voltage output with an analog voltage input range.


Description

This function is accomplished by using two simultaneous while loops each running a continuous DAQmx task. The top loop is the input task and when the input value falls within a range it uses a case structure to set the "Voltage output" local variable. The bottom loop is the output task and it is continuously outputting a voltage which can be set by the front panel or by the logic in the input loop.

Requirements

  • LabVIEW 2012 (or compatible)
  • DAQmx 9.5.5 (or compatible)

Steps to Implement or Execute Code

  1. Select the physical channels and set proper parameters.
  2. Run the VI.
