Abstract
A plant control monitoring system that can reduce communication traffic between a client and server to improve processing speed, and that includes: a server-side storage section provided in a server to store operation right processing information for a machine group on a client operation monitoring screen; client-side storage sections provided in clients to store duplicates of the operation right processing information of the server-side storage section; and operation right processing sections provided in the clients to correspond to each of the operation monitoring screens and that perform operation right processing based on the operation right processing information of the client-side storage sections. Operation right processing information for each client is stored in a global variable storage section of the client-side storage section, and operation right processing information for each operation screen is stored in a local variable storage section of the client-side storage section.
