Problems solved by technology

[0021] However, if, for example, a system constituent node is changed at a work site in a factory, it is necessary to correct the relevant DBs 11 to 15 of the system definition information group each time and generate a screen for displaying part, set the address of the system constituent node, and set the address of the system constituent node according to the correction The definition information download control function of the , therefore requires a large number of steps; this is a problem

Abstract

A system comprises a plurality of system component nodes each of which has a communication part that, when connected to a network, produces a unique global address and that transmits the produced global address, its attribute information and its positional information to the network; and an management node that manages the control of the whole control system. The management node has a communication part, a storage part for storing definition information; a display part for displaying an operating / monitoring window; a definition information generating part for generating the definition information from the global address, attribute information and positional information and for storing the generated definition information into the storage part; a window generating part for causing, based on the definition information stored in the storage part, the operating / monitoring window to be displayed; and a control function providing part for outputting, to the communication part, information in which the operations of the system component nodes have been defined.

Description

technical field [0001] The present invention relates to a control system established through a network, and more particularly, the present invention relates to a control system in which the system configuration can be changed in a short time. Background technique [0002] Control systems are available in systems of various sizes, from large control systems known as IA (Industrial Automation) (e.g. for the control and monitoring of factories) to medium-sized control systems known as BA (Building Automation) (e.g. , control and monitoring of air conditioning, lighting equipment, etc. in buildings), to small control systems called LA (laboratory automation) (for example, for a small number (several to dozens) of machine control and monitoring). [0003] This control system displays various information required for the control and operation system on the display screen of the display part of the management node used to manage the control of the entire control system, and if an ...
