How to run 3 operations through my USB-6210 at the same time w/o gettin an error

[mariachi]

 Hi, I am using a USB-6210 data logger from national instruments to collect data and run it through labview 7.1. However, when i try to run two labview files at the same time on two different channels in the data logger i get an error #50103 "The specified resource is reserved the operation could not be completed. How do i fix this?

There is only one multiplexer on that device, so only one program gets to control it.  If you need the data in two places, consider having one application obtain all the channels you need and then "serve" them to the other applications.  You can use VI Server, Datasocket, or raw TCP/IP (localhost).

Thanks a lot Photon Dan, but im not really sure how to go about using datasocket or a VI server?, sorry I am new Labview

Hi Mariachi,

I believe your overall project will be to collect data from your USB-6210 on multiple lines and save this to a file. Photon Dan is correct in the reason why you cannot use multiple tasks – because of the multiplexor, only one AI task can be run at a time. I would suggest putting all lines into one task and program, therefore eliminating the error, the need for multiple VI’s, and writing all data to a file at once. If you have further questions, I would ask that you post more detail about how you are collecting data (LabVIEW? SignalExpress? Etc) and your program. Unless you are connecting to other computers, you will not need to use VI Server, TCP, etc.

THANKS a lot ALL fixed
