Abstract
An advanced remotely accessible energy control system utilizes a client/server software architecture, and an “open” communication protocol, such as the well known TCP/IP protocol for design-in remote accessibility. Multiple graphic user interface clients can operate on widely available computers incorporating operating systems which are well suited to graphic user interface functions, while the energy control server and the input/output interface components can operate on a separate computer, using other or different operating systems, which are adapted to the processing performed there. According to the invention, the graphic user interface software is resident on one or more graphic user interface consoles or clients, so that processing for formatting data for display, and processing of input actions taken by a system user are offloaded from the server to the graphic user interface clients. Data describing the format of the display is stored on the server, so a user can move the graphic user interface software to another computer, connect to the server and view the system information, without transporting files describing the format of the display.
