Ladder programming as I have seen it used for PLCs was generally
limited to port I/O and combination logic - usually with a few
pre-coded niceties like timers and counters thrown in. The tools I
have seen were all platform specific and went directly to object code.


I would think it would be easy enough to make your own visual
programming tool, but the requirement for meta code baffles me. Do
you intend a further compilation step on the target? IME, ladder
programming is typically used for 8-bit MPUs - a platform might host a
very simple assembler and fix-up linker on-line, but something like a
JIT compiler is normally far out of the question.


Of course, if "ladder diagram" means something completely different to
you, then please disregard my ramblings.
