摘要:
A technique is provided for configuring an interface device. The interface device includes a plurality of device elements, such as objects configured in accordance with object-oriented programming concepts. A query from a general purpose viewer is received by the interface device, such as originating from a configuration station where the general purpose viewer is operative. The query is interpreted by server-side scripting executed in the interface device to identify the device elements and to display visual representations of the device elements in a design-time environment. The design-time environment and the visual representations are then transmitted to a configuration station. The device elements, their properties and functionalities may be altered by means of the design-time environment and the server-side scripting to create interface screens, alter device elements and their properties and functions, and so forth.

A technique is provided for configuring and interface device. The interface device includes a plurality of device elements, each having visual representation and a state engine defining a functionality. A server module in the interface device receives a query from a user viewable screen that includes the visual representations. The server module serves the user viewable screen to a general purpose viewer or browser, which may include a design-time environment. An access module, then, prompts each device to send an image defining its visual representation to a memory display context for inclusion in the user viewable screen. The access module works without reference to the respective functionality of the device elements.
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.
摘要:
A device interface includes device elements that are programmed to execute respective functionality and that have visual representations for inclusion in interface screen views. The elements are queried to provide images in a memory display context that is converted to dynamic content for inclusion in a design-time environment. The elements are also instantiated for generating a screen view for display on the interface device in parallel with the view provided in the design-time environment.
