<p>A process data management system ( 1 ) has a number of modules ( 2 -6 ) each of which can operate independently to capture, process, and record process data from machines (P 1 -P 6 ). The modules also communicate with each other via a messaging service ( 21, 40 ) so that data can be routed between components ( 22 -24, 42, 43, 45 ) of different modules using the Push mechanism. A Graphical data object (GDO) server ( 25, 45, 46 ) downloads applet instances to user browsers in response to the browser addressing a URL. The applet generates an output display in chart form of real time processed data.</p> |
