<P>PROBLEM TO BE SOLVED: To provide a synchronous system which has a master and a slave and is synchronized by a clock. <P>SOLUTION: The synchronous control system includes: a master 11 which has a generating section and a measuring section of transmission/reception time; a first slave 12 which includes a first return section and operates at first time when resetting is received; a second slave 13 which includes a second return section and operates at second time when resetting is received; a first cable which transmits a first signal to the first slave; a second cable whose length is the same as the first cable and which transmits the first signal to the master; a third cable which transmits a second signal to the second slave; and a fourth cable whose length is the same as the third cable and which transmits the second signal to the master. The measuring section calculates first time which is the half of time when the first signal is received via the first signal return section and second time which is the half of time when the second signal is received via the second signal return section. The generating section sets the second time to be zero and a difference between the second time and the first time to the first time when the second time is the longest in arrival time and sets the first time to be zero and the difference between the first time and the second time to the second time when the first time is the longest. <P>COPYRIGHT: (C)2013,JPO&INPIT |
