PURPOSE:To improve the input/output checking efficiency of the titled system by using the name of a connection element which keeps the direct input/output relation with an external device as a check name. CONSTITUTION:An input/output check circuit 18 reads the input state via an input interface 12 for the input fetched to a connection element group 10 of an electronic device from an external device. While the output signal sent from an input/output control circuit 16 is sent to the group 10 as an output via an output interface 14. The state of this output is read by an input/output check circuit 18, and the input/output state read by the circuit 18 is replaced in 1:1 with the individual name of each connector or terminal board, etc. of the element 10 by a converting circuit 20. This individual name is displayed by a display device 22. |
