以某企业的3．0 MPa高压空压机作为监控对象，引入SPC统计过程的控制算法，达到了利用S7－200 PLC的Modbus／RTU自由通信协议自动采集数据的目的。 Modbus主站为S7－200，从站为PD194E电测仪表，通过Modbus主站初始化，向从站发送读写指令与有效地址存储，非常方便地实现了Modbus通信主站的配置。

An enterprise with high -pressure compressor 3.0 MPa as the monitoring object , SPC statistical process control algorithm is introduced , so as to achieve the use of S 7-200 PLC′s Modbus /RTU communication protocol freedom automatic data collection purposes .Modbus master station for S 7-200, slave station for electricity meter PD194E, through Modbus master initialization , read and write commands sent from the slave station and the effective address stored , is very easy to realized configure of the Modbus communications master .
