ABSTRACT:
A user-definable menuing system for use in a process controller or other limited output computer. The process controller is adapted to receive user input from a limited number of buttons and display user output using seven-segment display units. The user may view the current value of and/or change the value of a variety of parameters. The more frequently used parameters may be associated with positions in an easily accessible customizable menu. The less frequently used parameters as well as the customization process are accessed through the conventional means of a menu tree. The parameters are associated with positions in the customizable menu through a special configuration mode. One button is used to cycle through each menu position and another is used to cycle through available parameters within a given menu position. The associations are stored in non-volatile memory such as an EEPROM to prevent the need to reprogram the menu each time.
