<p>PURPOSE:To correct presence information by simple work by connecting presence correcting piece to an input terminal formed on a corresponding station mark part on a presence correcting board so as to be detached from a system at the time of correcting the presence information. CONSTITUTION:When the presence information in a presence information file 18 is abnormal, each presence correcting piece 2 is disconnected from the bus 16 of a control computer 15 by an operator or the like and each piece 2 is inserted into its corresponding station 6 on the presence correcting board 1 based upon a station address displayed on the display device 14 of each piece 2. The presence information in the piece 2 inserted into each station is outputted from the board 1 and the presence information in the file 18 is corrected by the computer 15 based upon each presence information. Thus, the correcting work of the presence information can be simplified.</p> |
