Preferred OPC DCOM library for Delphi?

[Lars Fosdal 1793]

Does any of you have experience with OPC over DCOM, using Delphi?

We are looking for a library that is tried and known to work well, as there are a number to choose from at https://www.opcconnect.com/delphi.php

I have made good experiences with Kassl: OPC FOR DELPHI

The latest version also supports OPC UA, although I for myself had only used the older OPC DA components using DCOM up to now.

Thanks, Uwe. We did consider that our best option as well.
Now we just need Tetrapak to set up their OPC server correctly 😛
