Abstract

Several commercial communication bus implementations are nowadays available to implement distributed control systems for safety related applications in machinery. In regard to safety, the distributed control systems should be able to cope with all the communication induced error types. EN 50159 defines seven transmission system related error types or "threats" and introduces also several defences or risk reduction methods against the particular threats. This paper extends somewhat the list of the typical threats and the measures to minimise the risks. Furthermore, a documentation and analysis tool to support the safety analysis of bus based communication systems at signal level is presented. The tool is based on the Microsoft Access database software, and the analysis method is based on Hazard and Operability study (HAZOP).
