PURPOSE:To transmit trouble information to an operator quickly by sending abnormality information to an interface bus and displaying this information on an operator panel. CONSTITUTION:Abnormality information which an abnormality detecting part 1 is set to an abnormality information register 4 and is connected to an interface bus 6 between a control part and a panel part through a driver circuit 5. The abnormality signal generated from an abnormality detecting part 1 opens the driver circuit 5 to send the abnormality information to the interface bus 6. The abnormality signal closes a gate circuit 7 between the control part and the panel part on the bus 6 and sets the gate circuit 8 of the panel part in the input direction. Though the information from the control part is set to a driver 11 and is displayed on a display tube normally, the contents of the abnormality information register 4 are inputted to the display tube 10 if the abnormality occurs. The operator recognizes the classification of the trouble by the number displayed on the tube 10.
