Digital writer refnum error

[SD4r]

I am utilizing a digital writer for my particular code and for some reason if I try to attach a second digital writer to stop the output, I would receive the error in the title. I want the output to pause midway through the code and then start again before fully stopping. Is there something I can do to remedy this error. The second digital writer is placed outside of two while loops.

Thanks

Hello SD4r,

In order to help you with this problem, we need the follow information:

What device are you talking to? Is it the NI-ELVIS?

What error are you getting? We would need the error code number and description.

Can you explain in more detail what you are trying to do?

vinod,

You really need to stop hijacking old and unrelated threads.

Doing a read of something every x seconds is generally pretty trivial. There are several functions on the timing palette and you also have the timeout case with the event structure.

Hello Dennis,

                    I am hereby attaching the vi could you please help me in doing it..I have to do this within an hour

[Dennis_Knutson]

That VI makes no sense. All that it does is run every 20 seconds. It does not read anything except some Boolean in a higher level VI. There is no reason at all to have that PA Monitoring indicator and since you don't have anything wired to the property node output, you might as well not have this VI at all.

You will need more than a 1 hour to take the basic LabVIEW tutorial.
