| Abstract: | In this paper,we first introduce two typical design methods of sequential control program based on S7-200 PLC for Siemens,and then we point out the instruction difference between S/R and Sequence Control Relay(SCR) by comparison.Experimental results show that it has ability in realizing sequential control on single device or production process and it is also easy for the beginner to learn programming by using SFC(Sequential Function Chart). |
