PURPOSE:To perform automatically the function check efficiently without degrading the productivity of software by displaying connection states of input/ output terminals, which a connection information retrieval processing part retrieves, on a picture display device. CONSTITUTION:Connection information from a key input device 2 is inputted to a connection information retrieval processing part 7 provided in a microcomputer 4 by switching of a switch 8 and is compared with contents stored in a storage device 6 to retrieve connection states of input/output terminals between function blocks, and results are displayed on a picture display device 3. The display color of pertinent input/output terminals of DDC loop function block displayed on the device 3 is changed to yellow to display them if they are not connected yet, and the display color is changed to blue to display them if connection information is used for the block itself for the first time, and the display color is changed to green to display them if connection information is used for another block. |
