Cheap Plc

Welcome back, Chicagofred from Boston. You certainly have a knack for reviving old threads.

Why such antipathy towards ladder logic?

 

[Sergei Troizky]

OK.... I posted once on this site because I felt for the guy who wanted a cheap PLC. I sent him a lead on SPLat Controllers. Now I'm a wolf in sheep clothing? Why? Because you don't have to use Ladder Logic to program it? Try fitting in State Machine programming with Ladder Logic. It isn't easy. Or multitasking. You do know what multitasking is, don't you? Anyway, sell me on PLC that use Ladder Logic.

The PLC looks great for the money, but you judgements about ladder logic are strange.
You will be surprised, but most of PLC applications contain some kind of state sequence, and still are done in ladder; it is as simple as 1-2-3.
Multitasking? Any fragment of code may be considered a separate task. One can program as many as wanted.
