A remote supervisory control system is provided in which a master system performs monitoring and control of a plurality of slave systems, maintaining the fine control capability of the past, while enabling implementation with the minimum memory capacity. The master system is connected, via channels, to a plurality of slave systems, each of which has a plurality of individual control points in its purview. The plurality of individual control points are grouped into groups of individual control points having the same attributes, prescribed operations being performed on the status information of all individual control points within each group, the results of these calculations being taken as the status information of a representative control point. This status information is collected in memories located within the master system. The status information of the representative control point can, if necessary, be expanded to the status information of each individual control point and monitored, enabling separate control of the individual control points, and it is also possible to restore to monitoring and control of the original representative control point.

[ What is claimed is:] [9.] A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points,

[ What is claimed is:] [9.] A system for remote supervisory control, comprising a plurality of slave systems, each of said slave systems having a plurality of individual control points in its purview, and performing monitoring of and control of the statuses of each of the individual control points, and a master system which is connected to each of said slave systems via channels, and which performs overall monitoring of the statuses of, or control with respect to, said plurality of individual control points of each of the slave systems, wherein each of said slave system comprises:an individual control point table which holds information related to the statuses of each individual control point, which are collected from each said individual control point;a representative control point table holding statuses which represent a group of a plurality of said individual control points having the same attributes;a slave-side status change processing means which, when there is a status change in the information related to the statuses of each individual control point collected from each said individual control point, supplies that information as is to said individual control point table, and which supplies said representative control point table with said information after a pre-established operation is performed with respect to said statuses of said plurality of individual control points;a slave-side representative point configuration file into which are minimally stored the correspondence relationship between said representative control point and said individual control points which belong to it and an arithmetic expression which defines said operation; anda slave-side expansion/restoration processing means which works in concert with said individual control point table, said representative control point table, and said slave-side representative point configuration file either to expand processing with respect to a representative control point to processing of said individual control points or to restore processing with respect to expanded individual control point to processing with respect to said representative control point.
