I respect your judgement. Still in one of my last jobs they were
moving all control to work via a dedicated industrial PC that emulates
PLC's. The main program was in Java, and the bottom line was that I
couldn't count 1 mS pulses myself in Java and had to write a remote
control for the PLC and have written the lowlevel part in a different
PLC-compatible language. This makes a Forther cringe, probably.

Still somehow I thought it made a lot of sense. What they were moving
away from had was a couple of boards with 8-bit controllers. They face
the problem that those go end of life. Then the board has to be
redesigned and the program has to be adapted to a new processor.

Of course the PLC-computer has a lot of plug in modules for different
controls. Presumably these are black boxes with ... your 8 bit micro
controllers. But now the responsability for personal injury and
mission critical aspects is with very experienced designers of black
boxes.
