ENSURING FUNCTIONAL SAFETY REQUIREMENT SATISFACTION USING FAULT-DETECTABLE MICROCONTROLLER IDENTIFIERS

An application processor receives first and safety state information from first and second microcontrollers, and respective first and second sets of bytes forming a first identifier of the first microcontroller and a second identifier of the second microcontroller. The processor concatenates a safety message including the first and second safety state information, the safety message including the first set of bytes and the second set of bytes. The processor transmits the safety message to a second application processor of a safety controller, which separates, the first set of bytes and the second set of bytes, compares at least one of the first set of bytes and the second set of bytes to a data structure of known microcontroller identifiers, and verifies the safety state information based on identifying a match.
