flip flop logic plc

Alaric, welcome... and regarding your post above, and Daniels, you, Alaric, are 100% correct.

Daniel (no offense intended) makes assumptions based on the sequence of operand evaluation. That **MAY** work, on some platforms, but may (probably) NOT work on others.

Not that I want to moralize, but you really shouldn't rely on any particular platform (PLC, Operating System) to exibit quirks that you enjoy. Rather, take the extra bit, and the extra logic, to try to ensure that any logic you develop works on ANY platform.

Scan time really doesn't get hurt by an extra couple of rungs of ladder logic (pure boolean logic), so there is little reason to eek out every possible microsecond in a routine which makes it PLC Operating System dependent.

IMHO, of course.
