<p>PROBLEM TO BE SOLVED: To secure performance equivalent to the conventional art without using a transmission path with a higher speed than necessary in a case where a main controller and a device controller are connected with each other via a transmission path to control each device, and to eliminate needs for increase in signal lines configuring the transmission path and reconstruction of the main controller even when there is a change of a device connected to the device controller.SOLUTION: In a control device 11, a main controller 12 having a CPU 20 and a duplication register group 24, and a device controller 14 to which at least one device is connected and which has an input-output control register group 32 storing data for controlling the drive of the device and data indicating a state of the device, are connected with each other via a full-duplex system serial bus 40. The control device 11 performs duplication processing of reading each data stored in the input-output control register group 32 and transferring via the serial bus 40 to write in the duplication register group 24, at a cycle equal to or shorter than a count cycle of a system timer that becomes a reference for an operation of the CPU 20.</p> |
