Abstract
An industrial safety architecture integrates employee identity and enterprise-level security policy into plant-floor functional safety systems, allowing control and safety systems on the plant floor to regulate safe interactions with hazardous controlled machinery based on user identity or role. The architecture leverages existing employee identity and security policy data maintained on the corporate level of an industrial enterprise to manage identity- and/or role-based control and safety on the plant level. Safety authority systems at both the corporate level and the plant level of the industrial enterprise obtain employee and security policy data from corporate-level systems and provides this data in as SIL-rated manner to industrial control and safety systems on the plant floor, where the identity and security policy information is used by functional safety systems to control access to industrial systems as a function of user identity, role, certifications, or other qualifications.
