Datasocket connection loss to certain tags

[dondiggy27]

Hello all,

I've recently installed the patch LabVIEW 7.1.1, and I'm finding that 3 of my datasocketed connections using lookout protocol are having connection issues. 

1.  The datasocketed controls are on the faceplate of a subVI, and only the 3 controls that have their indicating LED blink between green and transparent.

2.  The datasocket connections, using lookout, to tags created on a RT compact fieldpoint controller, and interfaced through the tag engine.

3.  All other datasocketed connections appear to be running without a problem.

4.  When this subVI is ran independent of the main VI, then all datasockets operate without a problem.  The problem only arises when the subVI is ran embedded within the main.

Any ideas on what could be causing this problem would be greatly appreciated.  Thanks again everybody!

Hello,

LabVIEW 7.1.1 is no longer officially supported but I will do my best to assist you. Would you mind describing why you are using DataSockets, posting a snippet of your code and perhaps more information about what you are trying to achieve with your application? Based upon the information I have read so far, shared variable nodes would probably be better suited for you application but I will have to verify if they existed in 7.1.1.

Regards,
