Error 32812 FP Write.VI

[dannyjhu]

I have been running a cFP-2110 with labview 8.0 for about year without any problems.  Recently I changed the IP address on the cFP-2110 and since then I continue to get the error 32812 FP write.VI.  I have searched the message board about the error and tried several of the solutions without correcting the problem.  I went as far as deleting the remote system in MAX and then rebuilding the system with a new name and did have some success.  After rebuilding the system and then creating a new project and building a simple test vi the system worked error. However, when I close the project and only have the VI open, I get the same error 32812 FP write.VI.  If I reopen the project and run the test VI it runs error free.  Before changing the IP address and on the two other compact fieldpoint system I have in the lab I don't have this problem and have never had to keep the project explorer window open to run a VI.

On the system that gives me the error, when I have the project open the test VI is listed on the Project Explorer window under the My computer icon (just above dependencies and build Specifications).  However I on my other computer that is running LabView 8.5 and running two additional compact fieldpoint systems the VI's are not listed on the project explorer page.  I feel like the error has a simple fix that I am overlooking something but I can't figure out what I'm doing wrong or how just changing the IP address created the error.  Any help resolving the problem would be much appreciated.

Thank you

Hi Danny,

Can you explain what your VI is doing when you get the error? Have you tested all the cFP functionality in MAX?

Here is a related article about the error you are seeing:

Are you using serial communication?

If you can provide more information about the VI or attach it that will help troubleshoot.

Mark,

Thanks for you reply.  I'm sorry I didn't get right back to you posting the information you requested.  Here is the example program, the project and the config file.  The program runs error free if I have the project open in the project explorer.  If I close the project explorer window than the program gives me the error code most of the time, but not all the time.  I can't figure out why the project window must be open to run a VI.

Thanks for you help.

Danny

Mark,

I couldn't attach the .iak file for some reason.  If you need it I can email it to you.

Thanks

Hi Danny,

Unfortunately I am unable to repeat the error with my fieldpoint here and your software. The only thing I can think of is to check all of the installed drivers and make sure they are up to date. Here is a article that points to the visa drivers not being updated as the cause of the error, but if you haven't recently installed new drivers on your deployment computer than I'm not sure why you would just randomly start getting error and why it wouldn't happen when the VI isn't in a project.

Let me know if that helps or changes any of your results and I'll keep trying to find a cause for the error.

If you change the IP setting back to the way they were, do you still receive the error?
