I’m experiencing a problem in connecting Ignitions OPC DA to a Siemens WinCC OPC DA Server.
After going through all the pain in the world with all the DCOM settings, and failing to add the the server, I tried using some software (OPC Expert) to connect to the WinCC server, suspecting it would be a server side issue.
But, to my surprise, I can easily connect to the server with OPC Expert, yet in the Ignition Gateway the status is FAULTED.
I tried all the checkbox settings for the OPC DA connection, FAULTED nevertheless.
The error in the wrapper log is: Error connecting OPC-COM server.
com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x80040153; Invalid value for registry
I tried so many solutions, both from the forum, and from other forums, but none worked.
I will attach screenshots from the OPC client and Java log, maybe someone has a better idea than me.
Thanks for helping
