Building safety mechanism in industrial control system based on essential safety

Abstract

With the promotion of industrial automation and information technology, industrial control system becomes more and more complicated, which makes it more difficult to detect running errors. Errors usually lead to industrial accidents and put national economy and civil property at risk. In this paper, we propose a safety mechanism in Industrial Control System based on essential safety, which is the combination of information security and functional safety. This paper mainly describes the targets and functions of the safety of industrial control system, the state transition mechanism. This paper also gives the deployment of safety system and the experimental results, which achieving the safety of industrial control system. © 2014 Springer International Publishing.
