Conditional Error probe

[perky66666]

Hello！

I set a Conditional Error probe in my program, and selected pause if there is an Error, but it didn't pause when error appeared， why ?

You didn't actually have an error?  Perhaps it was a warning?  Or you didn't click the right check boxes?

With little to no information provided, I can only guess.

My guess is you didn't probe the right error wire. You seem to know there was an error, so I bet the error threw a popup alert, but the error didn't get passed through the wire you're probing.

LabVIEW programming is based entirely on dataflow and parallelism. This is incredibly powerful and has lead to its success over the years (coupled with the graphical programming), but is usually one of the first things that new developers stumble over. Here's a simple resource to become more familiar with how it works. The Highlight Execution feature is a great way to watch how your application utilizes dataflow.

I get mesmerized by all the dots racing around.  😉

Thanks for replying!

The picture shows what I choose. The error appears randomly, the error(not warning) actually appeared last time

You'll have to post a VI that demonstrates teh problem so we can try it out.  (Be sure the VI is named with regular alphabet characters so we can open it.)

Try troubleshooting with an indicator on that wire.  You can unbundle an error wire.  Try putting a conditional probe on the boolean wire coming out of the unbundle.
