Open Contacts Support for NI-9219 with CompactDAQ (DAQmx)

[CharlesD]

Overview

This example shows how to judge the input circuit if there is a load being connected.

Description

This code can be implemented in software as it is simply defined as a 2-wire resistance measurement using a 1kohm range. If the reading is railed (greater than 1kOHM), then you know the inputs are open, otherwise there is a load connected between the two inputs.

Requirements

 Software

•    LabVIEW 2012 or compatible
•    NI-DAQmx 9.5.5 or compatible

 Hardware

•    NI 9219
•    NI cDAQ-9178

 Steps to Implement or Execute Code

  1.Configure the following settings in the block diagram:

   (1)Select the physical channel.

   (2)Set the limit values and sample rate.

  2.Run the VI

  3.Check the result.

Thanks for posting.  Could you include a screen shot or two to give us an idea of what the code looks like?
