In the industrial environment, sensor and application data from machines in the field level are transmitted to a controller. If this is to be done wirelessly in view of moving parts, e.g. in driverless transport systems or cranes, radio links are used that are aligned with the respective fieldbus: The modules of the DATAEAGLE 4000 series are suitable for a transparent Ethernet connection, for example: Modbus TCP. For some fieldbuses, there are optimized radio data systems, e.g.: Wireless PROFIBUS, Wireless PROFINET and Wireless openSAFETY.
