Abstract
A system includes a safety relevant component that generates a data packet in response to receiving a request to perform a task and that communicates the data packet. The system further includes a first fail-safe chassis (FSC) that continuously generates a first and second chassis health signals, that determines whether the data packet is valid, and that selectively determines whether to de-assert the first and second chassis health signals based on the determination. The system also includes a second FSC that continuously generates a third a fourth chassis health signals, that determines whether a data packet is valid, and that selectively determines whether to de-assert the third and fourth chassis health signals based on the determination. The system includes a direct connect algorithm state machine that determines whether to instruct the one of the first and second FSCs to operate in a predetermined mode based on the chassis health signals.
