Abstract: A method that simplifies the exchange of data to facilitate delivery of data that relates to operation of a valve assembly to a Web-based user interface over a network. In one embodiment, the method configures an apparatus to receive data about the valve assembly in a first format and to generate an output in a second format, e.g., JavaScript Object Notation (JSON) format. The method may also configure the device with an architecture with multiple layers, wherein the architecture can exchange data in the JSON format between a first layer and a second layer. This architecture is configured to be lightweight as compared to the SOAP/HTTP architecture found in conventional techniques, typically deploying a Representational State Transfer (REST) structure that permits use of JavaScript Object Notation (JSON) format to communicate among the architecture layers and with the web-based user interface.

Abstract: A system and a method to display diagnostic and operating data on a trend graph via a web browser so that the data appears to trend in real-time. In one embodiment, the system includes a server with an architecture having multiple layers. The layers include a pair of first in, first out (FIFO) data queues including a first data queue and a second data queue. The embodiments utilize a timing structure with a plurality of timers including a first timer to regulate calls from the first data queue to a data source (e.g., a valve assembly or controller on a distributed control system), a second timer to regulate calls from the second data queue to the first data queue, and a third timer to regulate calls from the web browser to the second data queue for data to display on trend graph.
