After using DDE in my PC applications for many years to interface to PLC programs through RSLinx, I'm FINALLY looking at trying to use a more up to date and robust method.
The only alternative I seem to be finding is to use an OPC client. But with all of the associated fees and licensing, that's turning out to be an overly expensive proposition for the kinds of applications I have in mind.
Am I missing something? Or should I just go back to using DDE and forget it?
