This week is our fourth and final installment in our series on Cscape IEC 6-1131 languages. Sequential Function Chart is another graphical language - this time patterned around a traditional flow chart. It can be extremely useful as you define the steps, transitions and actions of your applications. One of the great things about Sequential Function Chart is that the actions you define in your application can be blocks of logic written in one of the other IEC 6-1131 languages. Be sure to attend this week as we close out this series.
