Scope
GB/T 41274-2022 is the English-translated version of 可编程控制系统内生安全体系架构.
GB/T 41274-2022 sets the endogenous safety architecture of a programmable control system, that is the safety built into the system itself rather than added around it.
It describes the architecture and its goal - keeping the integrity of the control system - and the safety requirements of each unit module, among them the protection through the whole life cycle, the comprehensive diagnosis and the way high availability is achieved, and then fixes the endogenous safety requirements of the system.
It is written for engineering designers, equipment makers, system integrators, users and certification bodies in the petrochemical, power and similar industries. Issued on 9 March 2022, it has applied since 1 October 2022.
