I recently wrote part 11 of the RSLogix 5000 tutorial I’ve been working on, and this part deals with the Sequential Function Chart editor.

I know there’s a lot of resistance to straying away from the established usage of ladder logic everywhere, but in this part of the tutorial I present a really simple way to use sequential function charts to express auto mode sequences in your RSLogix 5000 program that’s very readable, saves a lot of ladder programming, and integrates very well with your lower level machine control routines. Even if you’re an experienced RSLogix 5000 programmer, you’ll find this SFC introduction worth the read. Check it out.
