Control room: Users, designers benefit from remote graphics hardware validation
Control Engineering


December 13, 2007

Remote graphic units (RGUs) enable a control room computer to be located in a secure, temperature-controlled environment while the necessary user peripherals—keyboard, mouse, monitor and speakers—are where they can be most useful in the plant. Matrox Graphics Inc., a manufacturer of specialized graphics solutions, announces that its Extio RGUs have been certified for use with control systems and software from ABB, Emerson Process Management, Foxboro, GE Fanuc, Honeywell, and Wonderware. Matrox hardware is also enabling multi-screen operator stations, which provide greater visual real estate for more information-rich displays.

The Extio unit allows the control systems companies' HMI components to be connected to a host computer up to 820 ft. (250 meters) away via multi-mode fiber-optic cable. Control room operators benefit from increased space at the operator stations, a reduction in heat, and the removal of potentially noisy computers from the control room. IT managers are able to maintain security by moving the critical parts of a computer like the disks, memory, and processors into a separate room.

"Each operator also has the ability to connect up to four monitors to the Extio unit, which is equipped with a Matrox-designed graphics chip that offers unparalleled performance and image quality over a great distance," said Liv Stewart, sales representative for Critical Decision Systems at Matrox Graphics. The multi-display capabilities help increase productivity and reduce errors by allowing more information to be viewed at once, she said.
