Read User1 switch from RT at cRio-9047

[tokar]

Hi,

I try to read the state of "User1" button located on the cRIO-9047.

For other RT targets i have used "RT Read Switch.vi" found in NI_real-Time Target Support.lvlib.

But now when i using the same code i get Error code -1.

So my question is, how do i read the User1 switch state [on or off] from my RT target?

Found this and modified it to work.

Seems like my cRIO-9047 dont have all System Hardware functionality.

So i only using the first value witch is the User1 swtich state.

It works, but maybe someone can share other solutions, please do.

Hi tokar,

instead of using ArraySubset to get a subset of exactly one element you could use IndexArray instead!

Then you also don't need the FOR loop and the IndexArray after the loop…
