Study on the Time Delay of Single Sequence for Select Sequence

선택시퀀스 기능을 위한 단일시퀀스의 시간지연에 관한 연구

When we design the control system used Programmable Logic Controller(PLC), we program the main algorithm by Ladder Diagram(LD) among the standard language. We can substitute the select sequence function by the unique sequence. We can implement this function by the delay time. Therefore this thesis show the select sequence function by the unique sequence and we confirmed its feasibility through actual example.
