5.4 Safety communication layer structure

SafetyConsumers connect to SafetyProviders , they have prior expectations regarding the pair of SafetyProviderID and SafetyBaseID (e.g. by configuration). If this expectation is not fulfilled by the SafetyProvider , fail-safe substitute

9.1.1 SafetyBaseID and SafetyProviderID

SafetyBaseID and SafetyProviderID The pair of SafetyProviderID and SafetyBaseID is used by the SafetyConsumer to check the authenticity of the ResponseSPDU . SafetyProviderID and SafetyBaseID are usually assigned during engineering ... SafetyProviderIDs will reach its limits when the system becomes large, this document uses the SafetyBaseID for cases where guaranteeing unique SafetyProviderIDs is not possible. A SafetyBaseID is a universal unique
