Abstract: The heating control system which uses S7-300 as subordinate computer and WinCC as supervisory computer is introduced. Its hardware consists of SIEMENS S7-300 PLC and MM430 converter to fulfill the task of variable frequency constant pressure water-supply and field data collection. Industry supervision software WinCC 6.0 can achieve the task of monitoring．Practical operation demonstrates that the stability and reliability of the water supply system have been improved and the labor intensity of workers is reduced. The purpose of saving energy and reducing consumption has been realized.
Key words: PLC; constant; frequency converter; WinCC monitoring； heating
