Hey Sugam,

Did you try to look into de Developer Zone in NI? Here are some Articles that could help you to get started:

1. Tools for Troubleshooting OPC Interface Problems:

2. Accessing Remote OPC Server Using DataSocket: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P7fWSAS&l=en-US

3. Connecting LabVIEW to an OPC Server through a DataSocket Connection: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x2C7CAI&l=en-US

In short, you have to make your OPC server to run in your machine (you have to look into the documentation from the other manufacturer), and be familiar with NI Server Explorer (article 1 above helps with that) and you have to access the tag with datasocket or Tags (LabVIEW DSC). If you had LabVIEW 8, we introduced the concept of variables and you could configure the variable to access this tag.

Hope this gives you an idea what to do.

Do you have the DSC module with the tag engine?? This package makes it much easier to talk with opc servers.
