Hello,
I am lookink for a free code sample about OPC server.
I can't find that on the Internet.
We can find code samples for the OPC Client but not for the server.
Who has a sample ?
Thank you

Hi!
 
OPC is a COM based platform, an industry standard - thus there are lot of implementations, so you will probably not find the sample you are looking for. But as OPC is open, there are several useful sources you could download on their site. Check here: http://www.opcfoundation.org/Downloads.aspx?CM=1&CN=KEY&CI=285[^].
But you can also check those with server source in this list: http://www.opcconnect.com/source.php#toolkits[^]

5'ed, OPC used to be a DCOM only based technology, but that's some time ago, as the foundation created OPC UA, which does not depend on DCOM, some years ago.

Thank you. Yes, you'r right OPC does not depend on DCOM anymore, but the architecture concept is still the same, implemented on over other platforms.

>> the architecture concept is still the same
Which is a pity ...
It would have been much better if the industry went for something like OMGs' Data Distribution Service: http://www.omg.org/spec/DDS/

This is a free classic OPC server developed in Delphi: OPC Programming with Delphi[^]
 
The best thing to do is to join the OPC Foundation: http://www.opcfoundation.org/[^]
 
Along with the membership, you'll get example implementations for all OPC standards.
 
Best regards
