I'm wondering if anyone has encountered some decent software out there for documenting logic flow, particularly for control systems.
Preferably, something that would lend itself to documenting state logic. I've been trying to find something that will let me draw a GRAFCET type diagram (Sequential Flow Chart) but haven't been able to find anything.
I can use Visio if I need to, but it really doesn't lend itself well to control documentation.
I'm willing to pay but a free program is always nice.
Thanks!
