The TD6000 Series Intelligent Operator Interface is claimed to provide a rugged, flexible method of displaying and gathering operator data and communicating with control systems. Both water and dust tight, it is compatible with hostile environments. Applications can be developed using a MS Windows-based programming tool called the Westamp Application Builder. An array of I/O devices--such as two RS232 ports and eight optically isolated I/O ports--allow for interaction with many control-system components. Display duties are handled by a 40-character, eight-line LCD that can show graphics as well as text with individual control over every screen pixel. Westamp, Product Code 4304.
