Periodic process execution system, periodic process execution method, and periodic process execution program

摘要

The periodic process execution system includes a plurality of external devices that transmit a trigger for executing a periodic process, and a periodic process execution device that causes the external device to periodically execute a process. The periodic process execution device includes trigger transmission determination means and trigger transmission means. The trigger transmission determining means triggers the reception of the trigger from the external device, and the elapsed time from the time when the trigger was transmitted in the past to the external device that is the trigger transmission target has reached a predetermined trigger transmission interval. On the condition that the trigger is transmitted to the external device. The trigger transmission unit transmits the trigger to the external device based on the determination that the trigger transmission determination unit transmits the trigger.
