If the subsystem identified by the triplet is present and energized, it responds to the subsystem by sending it the content of its state control buffer. The supervisor registers the subsystem in a table and assigns it an address, equal to the detection rank of the subsystem (1, 2, etc.). If no subsystem responds during the pause interval, the supervisor goes to the next identifier, incrementing the serial number, then that of major version, then that of the function.
