Error -200488 occurred at DAQmx Write (Digital Bool 1Line 1Point).vi:2350003

[JayWW]

Hello,

    I'm attempted to setup some new hardware (NI PXI-1045 chassis w/PXI-8360, 5404, 5421, 2503, 6602, 6528, GPIB, and a 4070. The Labview program that was made for this hardware has already been debugged and has proven to work. I'm just setting up a new workstation and when I launch the .EXE I get the, "Error -200488 occurred at DAQmx Write (Digital Bool 1Line 1Point).vi:2350003".

I did some searching and really didn't find anything on it. I'm running the latest drivers that are available via the Package Manager. The older systems running the same .EXE are possibly running older drivers.

Any help would be greatly appreciated!

You didn't post your code, so we can't tell you how to "fix" it.  I presume you know how to find out what the Error number means, in this case:

Error -200488 occurred at an unidentified location

Possible reason(s):

Specified virtual channel cannot be added to the task, because it does not exist.
You cannot specify a physical channel. Instead, create a virtual channel using the DAQ Assistant or DAQmx Create Virtual Channel, and then add the virtual channel to the task.

Don't feel bad -- I just dashed off a clumsy DAQmx routine and got the same error, but the fix was obvious, and now my code runs fine.  If you can't fix your code yourself, post it so we won't have to "guess" ...

Hello Bob,

   I'm extremely new to Labview, what's the best method for looking up error codes?

Thanks,

Jay

Help >>  Explain Error.

Key it in.

If you want to search the forums or google for more information, search for error and for the number, but leave out the minus sign.

Here's the vi that is experiencing the error. This seems to occur during the initialization of the test system. I can't upload the main program due to it being proprietary.

You call a task called "Load Task".  Does that exist in Measurement and Automation Explorer in the PC you are using?

You call a task called "Digital Out J1".  Does that exist in Measurement and Automation Explorer in the PC you are using?

If the answer to either of those questions is no, then I think you have an explanation for your error number.

[JayWW]

Thanks for the reply! Unfortunately, I'm too new to Labview to know how to check if those items you mentioned are functional. I have begun the online Labview training though.

Random question: Does NI offer Labview help directly? Like someone who could remote into my system and diagnose and fix stuff? I'm on a bit of a time crunch and probably won't be up to speed quickly enough to solve it myself.

Thanks,

Jay

If you have an active SSP  (subscription service plan ??), then you could create a service request with NI and they might be able to help.  I don't know if they would provide help on a request that is you asking them to troubleshoot your code for you.

As for what I said, do you know what Measurement and Automation Explorer is?  Have you opened it up and looked inside to see if you have any DAQmx tasks set up there?

[JayWW]

Is that the NI MAX app? I have used that to setup the NI chassis. Where would I check for possible tasks?

Thanks,

Jay

Yes.

The tasks would be under My System >> Data Neighborhood >>  NI-DAQmx Tasks
