PURPOSE: To simplify maintenance works and make works efficient by displaying messages corresponding to alarm signals on a display part on a basis of alarm occurrence.
CONSTITUTION: Transfer earth signals ATH#1 to #N are generated through interface part INF by earth signal generation part NGEN on a basis of information from detection part DET which detects various kinds of alarm signal ALM#1 to #N and has a function to store them as required. The read of memory MESM is controlled by address generation part ADGEN which generates addresses, where messages to be displayed, etc., are stored, on a basis of information from timing generation part TIM and the detection part and address signals generted by part ADGEN, and a function to detect a read specific code in data detection part DDEC and display data are selected, and character signals to display part CRT are generated in character generation part CRGEN. As a result, works can be made simple and efficient.
