We are using a middleware for that. It abstracts industrial devices and
their protocols away, so that the application(s) would not care where the
process variables read and written come from. But it is a commercial
product.

And of course RS232, GPIB, TCP/IP is as much telling as ISA, PCI, PCIe. The
proper description should include the application level and everything down
to the transport, e.g. Steale autopilot, AK (list of commands, their
semantics), over TCP/IP.

If you want to communicate industrial devices, TCP/IP would be your least
problem. You need a middleware to decouple device-specific stuff from the
application logic.

I guess there exit some open source examples, e.g. AWS (though I did see
its sources.)
