PURPOSE:To indicate a troubled state with pulse stop similarly to the occurrence of trouble when a trouble reporting terminal is stacked, by transmitting pulses having a certain period when normality is decided as the result of trouble detection and stopping pulse transmission in case of trouble. CONSTITUTION:A preliminarily determined processing is performed for an input from an input terminal 6 by a main processing part 1, and the result is outputted from an output terminal 7. A trouble detecting part 2 detects troubles of the main processing part 1, and ''1'' is outputted as the detection result to a pulse transmission control part 4 in case of normality, but ''0'' is outputted similarly in case of trouble. A pulse generating part 3 generates pulses having a certain period and outputs them to the pulse transmission control part 4. The pulse transmission control part 4 operates AND between pulses having a certain period and the trouble detection result and transmits pulses having a certain period to a trouble reporting terminal 5 in case of normality but stops pulse transmission in case of trouble. |
