针对四站三工序生产线研制的自动控制系统，采用四台 S7-200PLC 构成 PPI 网络，应用 NE-TR 与 NETW 指令设计主站 PLC 的通信控制程序和各从站的控制程序。通过在实验室进行无负载模拟试验，证明该系统通信数据准确，功能稳定、可靠。

The authors of this paper have developed an automatic control system for the produc-tion line with four stations and three processes,which has a PPI network consisting of four S7-200PLCs,in which NETR and NETW instructions are used to design the communication control program of the master PLC and slave stations.Laboratory simulation testing with no load demonstrates that the communication data of the system is accurate,and that the performance it is stable and reliable.
