Abstract

PURPOSE:To detect a fault of a program in its early stages so that it can be restored to its former state, by providing a normal service card for storing an object program for instructing the execution of a control device, and a stand-by card having the same contents, and checking them in accordance with prescribed procedures. CONSTITUTION:In a control device 1 which uses a CPU card C1, data and program memory cards C2, C3, etc., in accordance with an object program of a card 3, whether a card having the same contents as said card is mounted to a slot S6 or not is detected, and when it is mounted, whether there is dissidence between the contents of both the cards or not is displayed by address display lamps 11A-11K, and also a data is displayed on data indicators 12A-12D. Unless said card is mounted, whether check information regarding the card 3 has been generated in a card 2 or not is detected, and unless it has been generated, the information is generated in every memory storing the object program of the card 3. In case when it has been generated already, the information is generated over again in every memory of the card 3, and whether there is dissidence between the present information and the previous information or not is displayed in the same way as said procedures.
