Stern Warning! When there is no error from the H/W, you should be extra careful with the way you code. 😉

The case structure only looks at the boolean part of the error cluster. If the wire has a warning (false + error code), this code will reset it.

I don't know if that's the actual intended case, though.

Maybe if things work properly then warnings will be generated, and you want to clear it?

EDIT: Beat again.

But that's why we have the "clear errors" primitive.

No need for case structures, tunnels, selectors, diagram constants, etc. (Well, they are still all there, just inside a system VI :D)

I think the clear specific error primitive is very recent...    I don't have it, and I'm running LV 2012.     

(I acutally do have a clear specific error vi in my user library, and have always wondered why NI didn't have it included themselves... )

Without the new primitive, the shown way does seem to be a fast and clean method to remove the warnings.

But you have the clear all errors (same, but without the upper input), which is similar to what is discussed here.

Personally I would probably have left out the diagram constant and used a "use default if unwired" output tunnel. 😉

AFAIK, there is no Clear Specific Errors VI. There is only a Clear Errors VI, and it is available in LV 2011 also.

Yup Clear Errors has existed since at least 2011.  Clear errors selectivly exists in 2014 nativly.  Of course OpenG and MGI have had their own versions of filtering errors for a while.

It is there in 8.5 also. If I remember correctly, it was there in 7.x as well.

Looks like it was introduced in 7.0. 🙂
