A computerized power management control system ( 10 ) includes a virtual modular relay device ( 82 ) for providing input and output data to and from a corresponding, actual modular relay device ( 47 or 49 ). Virtual modular relay device ( 82 ) is displayed in a window ( 90 ), with the upper left-hand corner of window ( 90 ) including a graphical depiction ( 92 ) of the modular relay device. Immediately below the graphical depiction ( 92 ) is a communications status indicator ( 94 ), which shows the status of communications (connected/disconnected) between the virtual device ( 82 ) and an inter-process communications server ( 52 ). Various fields ( 96 ) appear along the left-hand side of window to identify the modular relay unit ( 47 or 49 ). Below identification fields ( 96 ) are a plurality of buttons ( 98 ), each of which allow the user to activate a program module. Buttons ( 156 and 154 ) can be customized by the user to activate any program module. Tabbed pages ( 102 ) allow the user to quickly view numerous functions without cluttering the computer screen. The functions depicted on each of the tabbed pages ( 102 ) are user-defined. A program utility automatically configures the virtual modular relay device ( 82 ) graphic and links the virtual intelligent electronic device ( 82 ) to its actual counterpart ( 47 or 49 ) so that input and output signals may be sent between the two.
