Influence of Architecture and Parameters of SRCS on Safety Function Response Time

Response time is one of the most important parameter of safety functions for Safety Related Control System (SRCS) in time critical applications. During realization of this safety function for response time optimization, detailed knowledge of factors which have influence on response time is unavoidable. This contribution deals with analysis of measured response time reached by various SRCS architectures. These architectures are various in parameters settings, used hardware and used communication network. Final analysis shows influence of above described aspects on SF response time, what can be helpful for suitable architecture choose and parameters optimization when SF with SRCS is realized.
