Sino-German White Paper on Functional Safety for Industrie 4.0 and Intelligent Manufacturing


Sino-German White Paper

Conventional Industrial Automation Control Systems (hereinafter: IACS) are based solely on mechanical and electronic technology. Different devices or systems are isolated or have limited connectivity. Typically, it is common to use functional safety measures to deal with safety issues, which are mainly based on the general functional safety standard IEC 61508 and domains-specific standards, e.g. IEC 61511 for the process industry, IEC 62061 or ISO 13849 for the machinery sector and ISO 26262/ISO 21448 for the automotive industry.

However, with the rise of Industrie 4.0 and Intelligent Manufacturing (hereinafter: I4.0 and IM), more and more intelligent and digital technology is required for IACS. To meet this need, an increasing number of information technologies, communication devices and smart devices are being integrated into modern control systems. This increases the degree of complexity and interconnection among systems. Although this can increase efficiency and reduce costs for industries, the overall infrastructure will become more susceptible to internal failures and more vulnerable to cyberattacks. All of these new issues – including new hazards, e.g. security related attacks – therefore need to be considered to ensure that I4.0 and IM remain safe. Existing international standards need to be interpreted and amended to cover these issues.

This paper surveys and analyses existing standards, specifications and research to give an overview of safety for I4.0 and IM.
