PLC顺控指令在废渣回收系统中的应用

Application of Sequence Control in the System of Residue Collection

废渣回收系统的逻辑控制是典型的顺序控制,利用PLC可以简便、准确地实现该控制,以西门子S7-200小型PLC为例,介绍了顺序控制的编程方法和优点。

The system of Residue Collection is a typical sequence control which can be realized by PLC easily.This paper takes the SIEMENS S7-200 as an example to discuss the methods to control and the advantages of sequence control.
