CONTROL SYSTEM, TIMING DEVICE, AND PROCESS EXECUTED BY THE SYSTEM

A control system includes a timing device to indicate an elapsed time from a time point at inversion of the timing device, and a computer including a transmitter to start transmission of a control signal according to a control scenario determined with a predetermined signal to a predetermined device other than the timing device if switching of the timing device to an operational mode is determined, and to transmit a signal indicating the end of the control for the predetermined device if switching of the timing device to a nonoperational mode is determined. The control system reduces the number of steps of managing tokens, archives, and token passwords by a terminal manager, and further improves the security level of the terminal.
