Profibus is a proprietary protocol first introduced by BMBF (German department of education and research) and then used by Siemens. It is amongst the most popular protocols used in the automation industry. These displays support Profibus DP protocol.
Displays are available in 4 to 8 digits and from sizes 0.5” to 12”. Profibus alphanumeric displays are also available to show a message in numeric as well as text format. These displays can thus be driven from PLCs directly which support Profibus protocol.
