Title: DISTRIBUTED INTERFACE ARCHITECTURE FOR PROGRAMMABLE INDUSTRIAL CONTROL SYSTEMS
Abstract:
An integrated control system comprises one or more controllers each equipped to perform a control function and to gather data (ordinarily from sensors or a video camera) relevant to the control function. Each controller contains computer storage means, such as computer memory, for storing the relevant data and instructions, associated with the data, for causing a remote computer to generate a visual display incorporating the data in a predetermined format; and a communication module for establishing contact and facilitating data interchange with the remote computer. The remote computer, in turn, also includes a communication module compatible with the controller-borne module, and which enables the remote computer to download the data, including current video information and/or historical and/or reference video information, and associated instructions from one or more controllers. The remote computer also includes a facility for processing the instructions to create a user interface encoded by the instructions, and which incorporates the data. In this way, controller data is coupled to instructions for displaying that data, and this totality of information is continuously accessible, on a freely selective basis, to the remote computer.
