PURPOSE:To realize the monitor of I/O signals by a display and to simplify the constitution of a multipoint controller by mounting the monitor function of the I/O signals on a picture display. CONSTITUTION:A CPU1 which is composed of a memory microprocessor, etc., is provided in a multipoint controller, and a support tool 2 which supports the CPU1 is connected to the CPU1. An input module 4 and an output module 5 are connected to an internal bus 6 of the CPU1. The support tool 2 is used as a picture display, an I/O operation monitor 12 is displayed on a display screen 11, and the monitor parts are removed from the display panels of an input module 4 and the output module 5. The monitor functio of I/O signals is obtained by the support tool 2, and the constitution of a multipoint controller is simplified. |
