Abstract

PURPOSE:To quickly obtain the status change information of respective processors by sending a restart signal from a request signal sending means when a status change signal cannot be received within a previously determined fixed time after sending a status change sending request signal. CONSTITUTION:When a processor 1 to be informed outputs the 1st status change sending request signal to respective informing processors 6, 7 the request signal is received by request signal receiving parts 8, 9 and control parts 12, 13 start up respective status change signal sending parts 10, 11 to output status change signals. When the processor 1 outputs the 2nd request signal, similar operation to the 1st operation is executed, but if any fault is generated between the processor 1 and the informing processor 6 and a status change signal receiving part 3 can not receive a signal, a timer part 4 is driven by time-out and a request signal is supplied again from a request signal transmitting part 2 to the processor 6. Thus, the status change sending signal failed in reception is detected and the sending of the signal is rerequested to always know the up-to-date change information of respective processors.
