PURPOSE:To avoid system malfunction due to the erroneous mapping of a program etc. by setting the control program of the same type at both master and slave sides. CONSTITUTION:The initial processing part 1 of a computer 13 which receives data extracts the clock signal from an internal clock generating part 6 before execution of the initial processing and stores the clock as a starting time point. At the same time, the part 1 extracts the clock signal from the part 6 when the execution is over with the initial processing and sets the clock signal as an ending time point. Then the time required for the initial processing is calculated with the clock signal and from the difference between the start and the end time points. This calculated time is sent to the remote side via a transmission part 2. A time comparator 4 compares the initial processing time of a computer of the remote side with that of own computer 13. |
