I would like to find an OPC Client/Server that run on QNX 4.

I recently had the same issue. What I learned is that OPC is VERY
MicroSoft-centric. It relies on DCOM, which is not available for QNX. It
seems that there are very few OPC ports to non-Windows environments.

Hi Carl,
What most people seem to be doing is writing an M$ end OPC service with a
TCP based interface to the app running under QNX. The M$ task maps OPC data
requests to request from the QNX based server and then responds.
There is a speed advantage using this method, the native socket interface
will run much more quickly than DCOM over the network, the local OPC call is
pretty quick because it doesn’t reach the network.
See for example www.nautsilus.ru they have an OPC interface to my Opus
realtime database server.
Regards
Glyn
