Communication between 2 application

[Roderic]

Hello everyone,

I need help on a project. A VI launches testStand sequences, if the project is closed (only the VI is Open) everything works fine. But, if the project is open

or Vi compiled as an .exe application I receive an error from TestStand, it could not return the FIFO reference. It seems somehow the reference is private to the project or something...

I also get the same behavior using the Full featured UI shipped with TS2010. (I also have LV 2010).

This issue is also present if I try to use my Vi and sequences on another computer.

Do anyone encontered this problem, or has any clue about how to solve this problem?

Best regards,

We've got something working using shared variables, but I'd rather have the FIFO working (for data acquisition) so I'll be gratefull if anyone has any idea...

Do you have any code you could upload?

I am working with LV and TestStand.

I'll try to make a simple example that shows the problem as the project is too large to upload here.

Here is an example that shows the problem.

I also had the Network stream working, I was just wondering if network stream wasn't meant to replace FIFO in this case... But I dunno if there's a major difference between a FIFO and a Network stream from a stability and reliability point of view.
