What I mean is that you could certainly write a Java program that accepts a stream of "sensory data" written according to a specific protocol and outputs a stream of command instructions according to another specified protocol. You could even incorporate any ladder logic or other algorithms that were needed.
Ie, what you do is to write the
processing logic in Java, but leave it up to the system to supply and consume the input and output.
The main problem is that, not being an expert, I have no idea whether Java is (a) fast enough (b) robust enough (especially in terms of uninterrupted execution) or (c) low level enough to satisfy the needs of a PLC.
