It merges the traditional control technology, computer and communication technologies with a strong ability to control, flexible operation, high reliability and suitable for long-term characteristics of continuous work. It is very suitable for temperature control requirements. In the industrial field, with the rapid increase in the degree of automation, it is more and more important to monitor the process of control system for the users. The emergence of human-machine interface meets the needs of users. Man-machine interface can comprehensively monitor the control system, including process monitoring, alarm, data logging and other functions, so that the control systems have become user-friendly operation, the process of visualization and it will play more and more important part in the field of automatic control. This essay mainly introduces a design of temperature control system with SIMATIC programmable logic controller (PLC) and configuration software Kingview which is developed by Beijing Yakong Company. When programming, we use the PID control arithmetic software module which is contained in the program software STEP 7 -Micro WIN so that the program looks easier and operates more quickly. In order to monitor the control system and process data in actual time, we designed Human Machine Interface（HMI）with the configuration software Kingview. The result of experiment proves that this temperature control system could run quickly, accurately and have good stability, whi
