Remote connection to WinCC OPC Server in Server2008

Ignition

Dear Carl,

  1. We have completed the DCOM settings for Server 2008(Ignition Server) and Windows xp(WinCC Server).
  2. While trying to access OPCServer.Wincc remotely, i am getting the following error

1.com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x80040154; REGDB_E_CLASSNOTREG (Class not registered)

But locally we try with Matrikon,it is running

Plese reply me,

Regards
Shailesh

Your DCOM settings are still not perfect. Take a look at this DCOM post for more information:

With the “CLASS_NOT_REGISTERED” error, it may be possible that the OPC core components aren’t properly installed on the remote machine.

Please try the following:

  1. Download the OPC Core Components file.
  2. Stop Ignition
  3. Install that file.
  4. Restart Ignition and try again.

Does your remote machine have any other OPC software? I would guess that it doesn’t. It might be useful to install something like the Matrikon OPC Explorer to help troubleshoot. I say this because it will get rid of some of the additional service vs. application complexity, discussed a bit here. Once that works you can focus on Ignition.

Regards,
