Process values from Profibus PA or Foundation Fieldbus subscribers can be displayed using the new fieldbus displays directly on site. The LC display in the FD-48-T317/EX and FD-49-T317/EX models displays up to three process values that can originate from a single, as well as varying, fieldbus subscribers. The measured values are shown transparently and in a user-friendly manner, with a number amount of 30 mm and an additional 41-segment bar graph on the quasi-analog display. The values can be displayed either cyclically or through manual switching. Particular value was placed on simple operation. The fieldbus display is a “listener”, and not as a classic fieldbus subscriber. So the device can be effortlessly integrated into the network without host configuration or driver files. The user can completely parameterize the display using two buttons. The power is supplied via the fieldbus (< 10 mA).
