Abstract

In Factory Automation(FA) used by Programmable Logic Controller(PLC), Ladder Diagram(LD) is the most widely utilized and plays an important role in industrial control system. But recently, the study about Sequential Function Chart(SFC) is performed actively. When we program by SFC, generally, we design one routine from start to end. This method is difficult to design block control system, and we often make mistakes. In this paper, we propose the method that we design block control system and we analysis the difference of the method used this paper from conventional method.
