Can’t read data on shared Variable From remote PC

[MLR266_2]

I have read and think I understand the articles on ni.com about using shared variables over a network.

 

I want to take data from my development machine (D---175) running LabView 8.6.1 Professional and display it using a separate VI on a client machine (WIL---18).

Client machine has LabView runtime 8.6.1 installed.

 

I created a project with two sets of variables (server and client). The client variables are bound to the server variables.

 

I set the build so that the shared variable is in the support folder.

 

When I run both VI’s on the development machine everything goes fine.

When I run the server side VI and the executable on the development machine everything goes fine.

When I run the server side VI on the development machine and the client side executable on the client machine: NOTHING happens. The executable loads fine. I browse to the location where the shared variable is located and the program runs, but there is no data. Everything stays Zeros. I don’t get any error messages (on the client machine), nothing seems to be wrong except I don’t see my data.

 

The distributed systems manager (on the development machine) sees both computers. I am deploying the variables on both computers. BUT I get an error listed on the value field (no known value, connectiong, disconnected, process failure)

I applied the following fix with no difference (I re-ran the build after the fix)

My IT department tells me there are no firewalls between machines on our intranet. 

What else could I try to trouble shoot this?

Why are you using VI on one machine and executable on the other ? why r u not using executables or vis on both machine?

Also instead of taking variables at both machine and binding them, you can use datasocket and have your variables on one machine only. it will be much simpler.

[ronke]

do you deploy your all shared variables at the program initialize?

Hi

Keep your code at the server machine and keep the shared variable there. On the client machine use datasocket functions instead to reach data in the server computer (Its quite easy). It doesnt work with executables and shared variables ,there are no support for some commands you need, if I remember right.

I only have Labview on one machine. The other has just the run time environment. I could go with two exe's but it would only be an added step.

Yes. I used the files from here (http://zone.ni.com/devzone/cda/tut/p/id/5715) as a starting point.
