PROBLEM TO BE SOLVED: To reduce adverse effects when operations of a bus or device connected to the bus are abnormal.SOLUTION: A control device includes: a device that implements a prescribed operation in accordance with an instruction received from a bus to output a responce to the bus, and is reset by a signal received from a reset line; and master processing means and device pseudo means that are connected to the bus by the reset line. The device pseudo means is configured to acquire the instruction input to the device and the responce to the instruction from the bus; make estimations of a responce to the acquired instruction; when detecting a difference between the estimated responce and the acquired responce, output a failure notice to the master processing means; and output a signal to the reset line. The master processing means is configured to transmit the instruction to the bus, and when receiving the failure notice, initialize the device.SELECTED DRAWING: Figure 1 |
