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.

Abstract translation: 通过Web浏览器在趋势图上显示诊断和操作数据的系统和方法，以便数据看起来实时趋势。 在一个实施例中，系统包括具有多个层的架构的服务器。 层包括一对包括第一数据队列和第二数据队列的先入先出（FIFO）数据队列。 实施例利用具有多个定时器的定时结构，包括第一定时器来调节从第一数据队列到数据源（例如，分布式控制系统上的阀组件或控制器）的呼叫，第二计时器，用于调节来自 第二数据队列到第一数据队列，以及第三计时器，用于调节从web浏览器到第二数据队列的呼叫，以便在趋势图上显示数据。
