Safety and security checking in the design of Internet based control systems
Abstract
Internet-based control is becoming new generations of control systems, in which the Internet is used as a platform for global remote monitoring and control. The obvious benefit is to enable global collaboration and data sharing between operators from geographically dispersed locations. However, connection to an open network and the use of universal technology presents new problems that did not exist with the conventional design and construction of control systems, such as safety and security. This paper presents the safety and security checking procedures used in the design of Internet based control systems. A process control case study is used to illustrate the checking procedures.
