I just found out that I can actually wire the connect panel for sequence context and the refference with IP address and port number at the same panel. That should solve my problem.

Actually I am using a queue to pass script command from teststand to labview. Then in labview, it reads the output of the script. The whole purpose is to use this output to compare with the value of a variable in the teststand. Then adjust the command and send it back to labview again. I don't know how to attatch a screen shot here, so I paste it in the doc. "Local.Numeric In" is the one that I want to send to teststand. I know if I merge the sequence context part into my program, it is not gonna work since I can not call this vi directly by wiring the connect panel. How about sending this refference separetly?

QUOTE (TobyD @ Aug 20 2008, 02:14 PM) Right. This sounds close to what I need. The problem is that I am using a old version of labview. (7.1) could not open the 8.6 version vi. Is there a 8.6 version can be downloaded for free. Or do you have the sample vi in 7.1 version?

QUOTE (Tim_S @ Aug 20 2008, 09:23 AM) Thanks for your info. Eventhough, I use a TCP/IP connection, it acts both server and client on the same computer. I think that the problem is still between teststand and labview. (How to pass variable from labview to teststand where the variable initialized in teststand at first.) Martin

Hi, I am new to labview. Currently I am doing a automation romote control to a testing system through TCP/IP. The communication from teststand to labview has been done by using queue. It outputs some data. Now I need to pass these data back to teststand and do some caculation to them. Then loop them back to labview. anyone can help? thanks Martin
