Abstract

A control apparatus connected to a device includes a first control unit configured to execute a program, a second control unit configured to access the device to control the device, and a third control unit configured to control a reset of the control apparatus by transmitting a watchdog reset signal to the first and the second control units. When a condition for triggering a watchdog reset is satisfied, the third control unit transmits a watchdog reset prior notification to the second control unit before transmitting the watchdog reset signal. Upon reception of the watchdog reset signal, the first control unit executes a watchdog reset on the control apparatus. When a watchdog reset is executed, the second control unit controls the device to perform processing for making the device ready to accept a command based on information acquired upon reception of the watchdog reset prior notification.
