Abstract: In the present invention, device information is collected while real-time performance and high-speed performance of control-related normal communication are maintained. The distributed control system has: a central processing device; a central communication device; multiple terminal communication devices each having at least one controlled device connected thereto; an information storage device; and a network having a tree structure comprising multiple communication paths between the central communication device and the terminal communication devices, between the terminal communication devices, and between the terminal communication devices and the information storage device.
