    I am happy that this project (My OPC Client) is the most viewed article in this blog. Thank you.. :)

    There is a bug, My OPC Client can not read (browse) a tag which is located outside of group.
    So, I edit a source code. In this sub program :

    Private Sub treeOPC_NodeMouseClick

    I remove this condition:

    If e.Node.Nodes.Count = 0 Then

    and its 'else' and 'end if'
    Finally the program runs well.

    I change this project from using VS 10 to VS 10 Express.
    And I have updated the download link to the latest project.

    Best regards.

    How do you get your program to use the dll? I can't run the exe because it gives a Windows error, and the source code can't find 'Imports OPCAutomation'.

      Hi,
      you need OPCAutomation.dll installed on your PC. The DLL is in My_OPC_Client folder, but unfortunately it can not be registered manually (by using RegSvr32).
      The DLL (OPCAutomation.dll) is created by OPC Foundation, and distributed by Vendors like Rockwell, Siemens, KepWare, and automatically installed while installing their HMI/SCADA softwares.
      we get the DLL, installed in our PC because we install WinCC.
      So, what you needed is install one OPC Server on your PC.

    Hello Hadi,

    I'm trying to connect to a server from my laptop, the server is located on another PC. I'm unable to connect and as IP I give the IP of the network adapter of the server PC. The firewalls are off. Is there something I need to do specially? How to set the interface of my laptop?

      Hello..

      Please try to access shared folder located on remote PC.

      Some OPC server must have a same username and password.

    Hello,

    I downloaded your project and tried to connect to the Softing classic opc demo server. It works fine, but when I disconnect, the opc server doesn't close. I have to close the client for the server to close.
    This is not the case with other opc clients (where source code is not available).
    Do you have the possibility to try this scenario? Maybe there ist something wrong with my opcdaauto.dll ...

    I used the same dll to read the data from kepware server and everything is working fine but the reading process is very time consuming.I read some articles and found read from opc cache may optimize the reading time,so i change my code to read fr opc cache and yes it optimize the reading process but the value i get is always unknown,it seems like kepware does not update the cache, any idea to fix this?

      Maybe you must cek the OPC Server is able to receive connection. You can try first with other OPC client software.
