摘　　要：对基于S7-200 PLC和Flexible 2008组态软件的PID温度控制系统进行了研究,介绍了基于S7-200 PLC和Flexible 2008组态软件的PID温度控制系统硬件组成及工作原理,给出了实现温度PID控制的PLC程序设计和Flexible 2008组态软件设计要点。该温度控制系统可通过Flexible 2008组态软件实现动态监控,并可设置PID温度控制阀值。利用PLC可靠性高、抗干扰能力强和组态软件开放性好、界面显示组态功能强大的特点,使温度检测和驱动模块实现温度闭环控制。The PID temperature control system based on S7 -200 PLC and Flexible 2008 configuration software is studied. The hardware composition and working principle of PID temperature control system based on S7 - 200 PLC and Flexible 2008 are introduced. Gives the realization of temperature PID control PLC program design and flexible 2008 configuration software design points. The temperature control system can be dynamically monitored via the Flexible 2008 configuration software and PID temperature control thresholds can be set. This kind of control model not only uses the advantage that PLC has high reliability, strong anti - interference ca- pacity, but also uses the merit that configuration software has great openness, excellent interface display configuration, which realizes the temperature closed - loop control in temperature detection and driving module.
