Abstract

PURPOSE:To quickly and surely detect the runaway of a central controller of the stand-by side in terms of the act value by setting the time-over value of a program of the stand-by side at a central controller of the act side and counting the time during which said value reaches the set time-over value. CONSTITUTION:A clock generating means 15 which produces clocks at the prescribed intervals is added to an act side central controller 11 together with a counting means 16 which counts the clocks supplied from the means 15. Then a control means 17 is added to control the start and stop of the counting action of the means 16. together with a memory means 18 which stores the time-over value when the stand-by side is started, and a comparison means 19 which compares the count value of the means 16 with the time-over value of the means 18 and produces an interruption signal when said count value reaches said time-over value. Then the controller 11 starts a stand-by side central controller 13 and monitors the runaway of a stand-by side program. Thus it is possible to quickly and surely detect the runaway of the controller 13 at the act side.
