Beschreibung
Zusammenfassung:	A control system comprises a computing device, an input/output device, and an SOE device which are connected through a shared communication line. The input/output device transmits a status signal inputted from a control target to the computing device and outputs a control signal transmitted from the computing device to the control target, and the SOE device imports the control signal or the status signal to record a predetermined change thereof as event data, wherein the SOE device has a communication control portion which receives a read request from the computing device with a predetermined reception cycle, and transmits the event data to the computing device with a predetermined transmission cycle in response to the read request.
