A plurality of messages are sent to the safety device during the single communication session. Each of the plurality of messages includes the obtained key, an identifier of the source of the message, an identifier of the safety device, a sequence number indicating how many of the plurality of messages preceded the message during the communication session, a command for the safety device, and at least one cyclic redundancy code (CRC) based on content of the message. A next one of the plurality of messages is sent only after confirming that the safety device has accepted a most recently sent one of the plurality of messages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of conducting safety-critical communications","description":"An exemplary method of communicating with a safety device includes obtaining a key from the safety device that is useable for only a single communication session with the safety device.
