Wireless Data Exchange

In addition to all common bus systems and I/O signals, the KM6551 universal Beckhoff Bus Terminal system also supports data transmission via radio. It enables various types of transmission, based on the IEEE 802.15.4 standard. Compact construction (width 24 mm) and simple connection technology supports space-saving and fast mounting. The KM6551 exchanges data wirelessly at a gross rate of 250 kbit/s and therefore meets the requirements of industrial applications. The Beckhoff radio technology supports bidirectional data exchange between a master and one slave (peer-to-peer), a master and up to four slaves, and unidirectional data transfer from a master to n devices (broadcasting). Radio transmission takes place with 10 bytes of user data, independent of the bus system used. A diagnostic system integrated in the KM6551 enables monitoring of the radio link. The data exchange terminal uses the 2.4 GHz ISM band, which is available worldwide. A total of 16 channels are freely selectable for several transmissions i
