Hi Iskander,

Thanks for the post and I hope your well.

Firstly, are you trying to setup a server or communication with the server?

Communicate to OPC Server with LabVIEW DSC 8.0 and later using Shared Variables
The LabVIEW Shared Variable Engine (SVE) takes care of OPC for you.  To establish communication with an OPC server:

The steps are included in the follow KnowLedgeBase Article, 

How Do I Use OPC in LabVIEW?

If you could explain in a little more detail what your trying to do I will do my best to further support you.

Kind Regards,
James.

Hi James Hillman

Thanks for the attention

Why  didn't I see in the Tools/DSC/: Server Browser & Configure tags & Lounch Engine & Monitor tags...?

Isn't there an option somewhere to show shortened version of the menus?? I think somewhere under tools, options.

Hi Iskander,

What you see in your screenshot is what you should see with DSC.  What OPC server are you trying to access?  Are you trying to access LabVIEW Shared Variables via OPC, or do you have another OPC server such as NI-OPC, Kepware, etc?  The links from James should show you how to connect to any OPC server from LabVIEW with DSC.  Otherwise, we need to be able to identify what OPC server you are looking for.

Hi iskander,

I am afraid I need for information on what aspect of the setup isn't working - could you maybe pin-point the step in the guide that isnt working?

Hi James Hillman

Thanks

1. I launch the OPC Server NAPOPC and found there Ch02 and Ch03 (Boolean). I can control this variables on the .

2. In the LV I did File/New Project/My Computer/New /I/O Server. OPC Client. Choose NAPOPC Server. Ok. File/Save all.

3. Then : New/Library/Create Bound Variables and select from NAPOPC the  Ch02 and Ch03. Add. Done.

4. Save as. Deploy all.

5. But I don’t found Tools/Distributed System Manager.

6.  I created the VI: New/VI. And drag the Ch02 and Ch03.

After  I run this VI. The Error didn’t appear.

But the Ch02 and Ch03 didn’t change.

If I connected toggle switch  via Data Binding/DataSocket/DstpServer – all are working.

I don’t know where is my error?

Best regards

Iskander
