This control device, which constitutes at least part of a control system, has a master control unit and at least one slave control unit that is connected to the master control unit via, at least, a communication line. Each slave control unit has the following: a timing means that is synchronized with the master control unit; an input unit that accepts an interrupt signal; a means that, when an interrupt signal is accepted via the input unit, acquires timing-indicating information from the timing means and notifies the master control unit that an interrupt signal was inputted; and a means that, when a request is received from the master control unit via the communication line, transmits the acquired timing-indicating information to the master control unit via the communication line. |
