Abstract:
A user interface including a dual navigational menu system forming part of a configuration or programming procedure in a process control device such as a flow controller. The controller includes key pad by which the user enters instructions and data into the device, a display for displaying alphanumeric information and a key pad monitoring means for detecting a predetermined user input indicating that a configuration mode is desired. When in the configuration mode, the pressing of direction keys is detected to sequentially advance through a menu system comprised of a matrix of menu items arranged in rows and columns. Means is also provided for detecting the entry of position data which operates to directly select a given menu item to obviate the need for sequentially advancing through all prior items in order to reach the desired menu item. When a given menu item is activated, random access memory forming part of the device is used to store data entered by the user. A help system is also implemented including a key designated as a "help key" which displays context sensitive information for an activated menu item whenever the "help" key is pressed.
