(1)PID运算功能的实现 S7-200系列中CPU215/216具有32位浮点运算指令和内置PID调节运算指令等特殊功能。使用时，只需在PLC内存中填写1张PID控制参数表(见下表)，再执行指令：PID TABLE, LOOP，即可完成PID运算。其中操作数TABLE使用变量存储器VBx，用来指明控制环的起始地址；操作数LOOP是控制环号(常数，0～7)。编号为2、4、5、6、7的参数固定不变，可在PLC主程序中设定；编号为1、3、8、9的参数具有实时性，须在调用PID指令时填入
由于S7-200输入和输出为开关量，而变频器、压力变送器和振动变送器的信号为模拟量，因此EM235模块要实现D/A转换。一个EM235模块可同时扩展3路模拟量输入通道(接1路压力信号，2路振动信号)和1路模拟量输出通道(接至变频器)。 (2)起动 M1和M2各有两种起动方式，可通过转换开关选择变频/工频起动方式。 (3)运行 正常情况下，电动机M1处于变频调速状态，电动机M2处于停机备用状态。现场压力变送器检测管网出口压力(4～20mA模拟量信号)，并与预定值相比较，经PLC内部专用PID指令进行运算，得到变频器所需频率信号，自动调节电动机转速，达到所需管网压力。 (4)停止 按下“停止按钮”，PLC控制所有接触器断开，变频器停止工作。 (5)切换 当需从电动机M1切换到M2时，接触器KM2断开，KM1闭合，此时电动机M1工作在工频下，在变频器完全停止后，KM4闭合，变频器重新起动，电动机M2在变频器驱动下起动；完全起动后，KM1断开，电动机M1停止，切换操作结束。电动机M2切换到M1过程类似。
