shared variable

[Randy Woods]

I am using a shared variable in one of my applications.  The variable works great on the machine where I developed the code but if I try to run the code on another machine it will not run and I get a deployment progress window with:

Initializing...

Checking items for conflicts. This operation could take a while...
Preparing items for download. This operation could take a while...
Deploying My Computer
Deploying update.lvlib\\192.168.1.1\update deployment failed (error: -2147467259, LabVIEW:  (Hex 0x80004005) Unspecified error.).
Deployment completed with errors

I have also compiled the vi on the original machine and then run it on the other machine and it runs but with an error relating to the shared variable.  I think that I have the right toolboxes installed but I am not sure why it will not run correctly.

Hi Randy,

That error can be caused by the correct ports not being open for the shared variable engine. Can you check to see if you have a firewall enabled that might be blocking port 1024.

I would also like to have you try to make a single process variable and see if you can deploy it. If you still receive the error then it is related to the variable engine itself and not communication.

Let me know your results.

The single process shared varriable appears to work.  What is the difference?  I am not using a network but I would like to write data in one while loop and read it back in 2 other loops.

Hi Randy

A single process shared variable is only available on your PC and allow you to share data across multiple VI's. These perform similarly to a local variable and should accomplish what you are looking for.

Hi,

Im getting deployment error using my Network Shared Variables under .lvlib.

Here's the deployment status log.

I don't have any error on my target vi. Im using CVS for my vision project.

All my variables are added on my RT Project. I am not sure of the error. And how to fix it.

Hi there,

I would look into first creating a very simple shared variable application to make sure that the shared variables are working properly.  

Also check out this article.  It sounds pretty similar to what is going on here.  Why Do I Get Error 2147220735 When I Run My VI On a Real-Time (RT) Target?
