Abstract

A system and method for displaying and configuring parameters in a fieldbus configuration system. The fieldbus configuration utility first determines the devices and blocks present in the system, and then determines the parameters of each block. When the parameters are displayed, an object is displayed proximate to certain of the parameters. The object includes a color and/or shape which indicates the type or class of parameter. The user can also configure alarms and trends using the improved graphical interface of the present invention. The user configures alarms and trends by assembling a graphical program or wiring diagram on the screen which comprises a selected one or more block icons and an icon representing the device receiving the trend or alarm. The system also includes a periodic update window which is used to obtain periodically updated values of selected parameters.
