PLC的PID功能在恒压供水系统中的应用
PID Function of PLC Applied to Constant-Pressure Water Feed System
【摘要】 本文以变频调速恒压供水系统为例,简要介绍了S7-200系列PLC内置PID运算功能的应用。系统的逻辑控制与PID运算由PLC完成,供水压力由PLC的模拟电位器设定,系统组成简单、运行可靠。
【Abstract】 Take the example of vary-frequency speed-readjustment constant-pressure water feed system, this paper shortly introduces the inside PID function application of S7-200 series PLC. The logical control and PID operation are completed by PLC, water pressure be sited by regulation-resistance. The system composition is simple and running is reliable.
