Abstract
Abstract A display, a display method and an apparatus are disclosed which produce a summary display depicting function states using discrete state bars centered in one window of a two-window display. The other window on the summary display includes meters for the parameters along the active path of the status tree for the most relevant function as determined by the operator. Each meter indicates not only the current value of the parameter being monitored but the ranges of the different function states as they correspond to the parameter being displayed by the meter. Each meter also carries a data quality indicator. A second level display is provided which depicts the status tree with the active path highlighted allowing the operator to review the decision made by the status tree. The second level display also indicates the values of the parameters used in the decision-making process and includes a miniature version of the summary display that allows the operator to continuously monitor system summary status while reviewing the second level display. A third level display is also provided which depicts detailed information on the sensor values of the parameters being monitored as well as the exact questions being answered by decision trees of the process control monitoring system along with the answers. This third level display also includes a miniature version of the summary status display.
