Interesting -- is that still different from what we would usually call a computer instead of a PLC? I had thought the original PLC's were implemented with relays or simple switching elements and were programmed with ladder logic, which persisted into the microprocessor era because control engineers understood it, it had good verification methods, and it was hard to go wrong because its range was so limited. Once you get away from that, are you not doing just ordinary programming?
