Radio module
viBlu Helmholz

The PROFIBUS radio system viBlu is a virtual cable that permits the linking of distributed I/Os or intelligent devices (e.g. rotating tables, conveyor systems, etc.) by means of radio. Data transmission is performed via Bluetooth in the license-exempt 2.4 GHz band and supports the PROFIBUS baud rates of 9.6 kbps to 1.5 Mbps.
Depending on the local circumstances, transmission distances of up to 100 m are possible.
Use of the PROFIBUS radio module is possible in single-master, and in multi-master systems and permits full PROFIBUS expansion. At present, only PROFIBUS DP-slaves are supported behind a viBlu slave.
The PROFIBUS radio module is powered with 24 V DC from an external power supply.
A 9-way SubD socket is used for the PROFIBUS connection. Moreover, an USB port is integrated to be used for parameterization of the radio link. 5 LEDs on the device provide information about the operating status on the PROFIBUS and on the radio side.
Antennas with a larger gain can optionally be connected to the radio module through an RP-SMA socket on the device to optimize the range. Outside Europe, use of antennas with a gain of more than 10 dBi is permitted, enabling radio-relay systems with a range, for example, of up to a few kilometers.
