Abstract
The aim of this article is to identify and discuss some issues that can be encountered in designing the industrial automation and control systems (IACS) for implementing safety functions. In a functional safety standard IEC 61511 for the process industry such systems are named the basic process control systems (BPCS) and the safety instrumented systems (SIS). In a generic functional safety standard IEC 61508 they are depicted as the electric / electronic / programmable electronic systems (E/E/PES). The role of these systems is to implement safety functions for effective reducing and controlling the individual risk and/or societal risk in life cycle in relation to tolerable risk levels defined for given hazardous plant. Some aspects of potential influence of danger failures of the E/E/PES or SIS on the plant safety are considered. The influence of common cause failures (CCF) in verifying the safety integrity levels (SIL) achieved by safety functions is evaluated and discussed.
