摘要
A control system database server is disclosed that includes a data compression facility that implements a compression test sequence on streams of time stamped data points rendered by components of a control system. A deadband/time override is incorporated into the compression test sequence to ensure that a previously received data point, within the stream of received data points, is saved within a designated time period even if the compression test sequence would have determined that the data point be discarded. The series of compressed/tabled data points, corresponding to the received steams of data points, are thereafter provided by the historian to requesting client applications that, by way of example, retrieve the compressed, time stamped data point streams for the purpose of constructing and displaying trend graphs.
