Setting makes subvi frozen Labview 10.0

[Ott]

Hi,

I had a strange issue. Same main program, same subvi - it used to work. When came to subvi, the subvi popup and users could interface with it. I am not sure what I touched, the subvi will working if use step function , but not for continuous running. What I noticed is in the block diagram, when I right click on the wire to set the breakpoint, the function is not listed there anymore - basically the probe functions are hidden.

What's the setting triggering the functions to hidden?

Thanks,

Ott

Hi Ott,

maybe you disabled the debugging features in the VI properties...

The debugging advice above is a good point to start but I think there is more (or less).

There are a few things that are not clear yet:

• You mention "frozen" in the title but don't mention it again in the body of the posts. Debugging setttings do not "freeze" anything. Is this a different problem?
• Are you saying that the "single step" function still works?
• Are you talking about the continuous run function or something else?
• Could it be you have a breakpoint set somewhere? (Any red frames or dots on the diagram)?
• Also try "menu...edit...remove breakpoints from hierarchy"

Pls. see the attached example. Run test_sample.vi and you will find out what I mean freeze.

I put two breakpoint there, if use step after the first breakpoint, it works.

Thanks,

Ott

your "test sample.vi" proerties (VI properties...windows appearance...customize) are set to "modal". Set it back to normal.

(A modal window will be on top of all other windows and will not allow interaction with other labview windows, such as your subVI. Check the help)
