<p>PURPOSE:To achieve time coincidence with reference time can not be supplied from an external timer by transferring the measured time of the internal timer of a specific subsystem to another subsystem, and by making the measured time of the internal timer of each subsystem coincident by the transferred measured time. CONSTITUTION:Subsystems S0', S1' and S2' have internal timers T0, T1 and T2, respectively. When the subsystems S1' and S2' are started a time enquiring function ENQ is started and a time enquiry signal is sent to the S0' through a communicating function CU. The S0' starts a time casiting machine ANS to return a time signal which includes the time t0 of the internal timer read through a time updating function CTL. The S1' and S2' set the received time to times t1' and t2 of the internal timers. Thus, the time in this system is unified without the intervention of an external timer.</p> |
