Looking for Sequential Programming resources.

I'm looking for any resource on Sequential Function Chart programing. Books, websites, papers, etc. Thanks for sharing, Siso.

Thanks Ken
I kept searching online and found other websites with SFC info:
http://www.batchcontrol.com/s88/sfcs.shtml
http://www.easydeltav.com/BOL/mergedprojects/Modules/html/seqfunref.htm

Sequential Function Charts were derived from the French Grafcet as this Wikipedia article also states. Grafcet was however a design technique, whereas SFC is one of the IEC61131 approved programming languages. Some of the advantages of knowing the basics of Grafcet are:

• you can use Grafcet to design a PLC program even if the PLC has no SFC abilities
• you can use Grafcet also to design hardwired relay logic, electronic logic circuitry or even pneumatic circuits

Some websites dealing with Grafcet are:

• http://www.lurpa.ens-cachan.fr/grafcet.html
• http://www.youtube.com/watch?v=2nGIjcyGXbc&fmt=18
• http://hubpages.com/hub/Grafchart_Grafcet_SFC_software

No need to say I'm a big fan of Grafcet as a design technique.

Kind regards,
