<p>PURPOSE:To facilitate the due processing against the abnormality and to reduce the burden of an operator by displaying an affecting range of control system of a central control board based on an output abnormal signal when an input/ output substrate of a local control board has the abnormality. CONSTITUTION:An output abnormal signal S2 is inputted to a subject substrate position detecting logic 17 and the position of abnormality is detected. An influence logic detecting part 18 detects an affecting range of a control system based on the position of abnormality, the position of an input/output substrate set previously, and the affecting range format. An equipment operating state detecting part 19 detects the operating state of the equipment affected by the input/output substrate. Then a pilot lamp lighting state changing part 20 turns on a pilot lamp 15 different from the normal one for a controlled system to be affected based on the affecting range detected by the part 18 and the equipment operating state detected by the part 19.</p> |
