Abstract

A first processor console includes a first display screen and a first storage device for storing panel templates containing fixed panel information for display on the first display screen. A second processor console includes a second display screen and a second storage device for storing panel templates containing fixed panel information for display on the second display screen. The first processor console transmits to the second processor console an identification of a panel template for display on the second display screen. The second processor console receives the panel template identification, determines if the panel template identification identifies a panel stored in the second storage means and displays the panel on the second display screen if the identification identifies a panel stored in the second storage device, and requests transmission of the identified panel template if the second storage device does not contain the identified panel template. The first processor console also transmits variable information to the second processor console for merger with the identified panel template. The first and second processor consoles utilize standard operating systems to participate in the remote operations.
