SCADA system for process monitoring and data handling has client server arrangement providing low data transmission loads

摘要

The supervisory control and data acquisition, (SCADA) system has a client/server architecture with at least one client [7] and a server [1] coupled to an input/output process controller [19]. Process data is stored in a client Cache [12]. Other units [3,10,11,13] provide communication of data around the system.
