Interface method and system for enhanced data and memory management

摘要

A technique is provided for enhancing the performance of an interface device. A collection of device elements having properties including a visual representation and a functionality are instantiated in a global container. The global container includes the device elements that are required for various screen views. Device elements that are not required in a currently displayed screen view are torn off in the global container so that memory and processing requirements are reduced, while increasing the speed and performance of the interface, particularly in switching between screen views.

主权项

1. A configurable interface device for a process control and monitoring device, comprising:
a plurality of device elements, each device element having properties including a visual representation and a functionality of the respective device element, wherein the plurality of device elements control and monitor the process control and monitoring device; a first screen container in which are instantiated first selected device elements having visual representations in a first interface screen; a second screen container in which are instantiated second selected device elements having visual representations in a second interface screen; a global container in which the first and second selected device elements are instantiated but in which either the first or second device elements, respectively, are torn off based on whether the second or first interface screen is currently being displayed; and a processor configured to execute code for instantiating the plurality of device elements.
