PURPOSE: An event processing module and a PLC system is provided to reduce the load of the device which is generated in a central control by performing time synchronization through an event processing module in each base. CONSTITUTION: A time synchronization controller(180) supplies time information. A nonvolatile storage unit(190) stores event information and event generation time. A main controller(130) stores the event information and time in the nonvolatile storage unit in reference to time information. An input insulating unit(110) transfers an event signal and electrically insulates the outside and inside of an event processing module. |
