WinCC v7.5: OPC Server Error

 Hello Calt,

I have exactly the same problem with WinCC v7.5.

I can not browse OPCServer.WinCC....

Did you find the solution?

Hello,

I have WinCC 7.3 Upd 4 installed.I wanted to check my Tags defined in S7 Protocol from OPC Scout.

When I open OPC Scout  -> Local COM server -> OPCServer.WinCC I have an error: E_UNKNOWN_ITEM_NAME IOPCBrowse.Browse. (screenshot)

I have checked below hints, which I found in other topics:

- I have rerun the Simatic Security Control

- The process "sopcsrvrwincc.exe" is running in the Task Manager

- WinCC cannot browse itself - I created a new connection for OPC in Tag Management, but the "Test Server" button doesn't find the OPC Server on this computer (screenshot)

- My project is in runtime

What can be the source of this error? I'm waiting for other suggestions to try.

Best Regards

Hello Murof,

I use OPC DA.

I want to read data  with Siemens OPC Scout on the same PC that is running WinCC / WinCC OPC Server.

WinCC Runtime V7.5 + SP2 + Upd 1

Hello Djordje

do you use OPC UA Server or OPC DA (DCOM based)?

With which Client do you want to read out/browse the WinCC OPC Server?

Which WinCC Version do you use exactly (With SP and Upd)?

Bye Murof

Hello Djordje

Check out this FAQ:

If you have problems with browsing it could also be good to refresh the temporary data:
