i want to develop it. but i don't know enought freepascal and lazarus programing.
if you use simens plc you can test libnodave components. it has delphi and pascal version. may be it can port for lazarus.

Guzzi:
You will find a OPC Client Tool Kit for Delphi and Lazarus at:
http://www.dopc.kassl.de
It is not free, you have to pay for it.

avra:
There is a lot of free Delphi OPC server/client code here:

Maybe with latest COM/DCOM advances in Lazarus, conversion would be possible with some manual effort. Anyway if you decide to try it then I suggest using SVN Laz+FPC versions.
