基于PLC的锅炉内胆水温控制系统采用PLC作为控制系统的核心，使用西门予公司的S7-300系列PLC编程软件中的PID功能块来实现控制算法，通过和计算机的通信实现数据的自动处理和操作的远程控制。监控画面采用西门子公司的Wincc组态软件来制作，从而实现对KP、TI、TD三个参数的在线修改，以及实时监视被控对象的运行状态-PLC-based TANK boiler water temperature control system PLC control system as the core, Si

System is based on Siemens S7-200PLC as a slave in PC Britain S7-300 as a virtual master temperature PID control system.
