With the new PSI-Bluetooth-Profibus set from Phoenix Contact, Bluetooth technology is used for wireless fieldbus communication with Profibus. The Bluetooth frequency-hopping technique is particularly beneficial in metallic environments and also shows its strengths when coexisting with other wireless systems.
The system enables devices to be started quickly, as there is absolutely no configuring to be done when establishing a Bluetooth connection. The Bluetooth converters are pre-configured for a transparent, password-protected point-to-point connection. After installation, the devices automatically connect themselves, therefore permitting a wireless Profibus connection with data transfer rates of 187,5 Kbps. By using a high-performance transceiver based on Bluetooth 2.0 technology, ranges in excess of 150 m can be achieved.
With the set, complex Profibus connections to moving devices, which were previously only possible using costly drag chains, slip rings or other cable-based solutions, can now be quickly implemented at a favourable price.
