Based on the introduction to characteristics of high reliability, high intelligence and real time of modern industrial production, this article analyzes the requirements for monitoring and control systems. And necessary competences which monitoring and control systems must possess are introduced. This paper proposes several rules for designing real time monitoring and control systems with high reliability. A model framework and prototype based on PLC for real time monitoring and control systems with high reliability has been developed. This paper gives an example of the model applied in the chemical industrial production. It shows that the model has the characteristics of convenient operation, easy realization and high reliability.
