Study on the method of Block processing by SFC

SFC에 의한 권역별 처리 방법에 관한 연구

Ladder Diagram(LD) is the most widely utilized among many sorts of existing programs using for the design of process control system. But it is very difficult to grasp sequential flow of control logic. In this paper, we proposed the method that we can control a lot of blocks. We used PLC in process control system. And, in order to design we used Sequential Function Chart(SFC). In this paper, we proposed the method of block contro. and confirmed feasibility through a simulation.
