在西门子S7-200的编程软件中本身已经集成了PID控制指令，但使用不够灵活且受到使用控制回路的限制。以增量式PID算法为基础结合积分分离PID算法和带死区PID算法编写的改进型PID控制子程序功能更加强大，且不受控制回路的限制，可以在S7-200的控制程序中重复调用，具有重要的工程适用意义。

In the programming software of Siemens S 7-200 itself has integrated the PID control in-structions , but not enough use flexible and limited to the use of control circuit .With improved incremen-tal PID algorithm as the foundation combined with integral separation PID algorithm and PID algorithm with dead zone PID control subroutine function more powerful , and from control loop limitation , can in the S7-200 control program repeated calls , has important significance for engineering .
