Distributed Control System and Control Method Thereof
First Claim
1. A distributed control system in which a central communication device and a plurality of terminal communication devices connected to target devices to be controlled are connected through a network,wherein in response to receiving input/output performance of the terminal communication devices previously set in input/output performance storage tables of the terminal communication devices, the central communication device generates communication paths between the central communication device and the terminal communication devices through the network on the basis of the received input/output performance and sets the generated communication paths in communication path setting units of the terminal communication devices, andwherein the terminal communication devices transmit or receive data to or from the central communication device through the communication paths on the network set by the central communication device.

Abstract
In a distributed control system including a central communication device, terminal communication devices to which target devices to be controlled are connected, and a network including multiple communication paths connecting the central communication device and terminal communication devices, each terminal communication device includes a calculation input/output performance storage unit storing input/output performance of a calculation unit for controlling the target devices to be controlled and a control input/output performance storage unit storing the performance of the input/output control units of the target devices to be controlled, and the central communication device collects input/output performance information previously stored in these storage units, determines communication paths of the terminal communication units and a packet division method in such a manner that an amount of a communication data of a network and response performance requested of the distributed control system are satisfied, on the basis of the collected input/output performance information and sets the determination results in the terminal communication devices.
