Example using NI-9482

barney99 — Fri, 10 May 2019 21:41:35 GMT

I am looking for a simple example for opening and closing the switches on the NI-9482 in Labwindows. There is an example in LabView but it is not clear to me what functions need to be used to open and close the switches.

Thanks

Hi Barney,

Check this information https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x12BCAQ&l=en-US

In point 6, you will find Special Considerations for Form C Relays like the NI-9482.

Thanks for the reply. But I do not understand the path forward here....

Maybe I am not understanding something but all I need to do is open or close a switch on your NI-9482 module. Normally this is one line of code for a microprocessor (very simple). However, the link you provided seems like development of a driver to operate switches and looks like a very involved process with no clear path on how to actually implement in a simple Labwindows example code. Are you saying that there are no functions within Labwindows to simply open or close a switch???

Hi,

This is the way that you usually program this module in LabVIEW https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P8TMSA0&l=en-US

And here you can find how to use the DAQ assistant in CVI https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000YGZeCAO&l=en-US

Additionally, some relays can be controlled using the DAQmxSwitchOpenRelays and DAQmxSwitchCloseRelays functions documented here:

https://www.ni.com/docs/en-US/bundle/ni-daqmx-c-api-ref/page/daqmxcfunc/daqmxswitchopenrelays.html
https://www.ni.com/docs/en-US/bundle/ni-daqmx-c-api-ref/page/daqmxcfunc/daqmxswitchcloserelays.html

You can find an example in the following location on your computer, if you elected to install text-based DAQmx examples during the installation of DAQmx:

¿C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Switches\Control Individual Relay¿
