SCALANCE W devices support tags of the AeroScout company. Tags are battery-operated
RFID sensors that send their data cyclically as multicast frames.
Among other things, AeroScout tags have the following features:
●
If a tag is fitted to a device or material, it is possible to monitor whether a selected
ambient temperature is being maintained.
●
Here, a tag can also supply information indicating whether it is in motion or stationary.
The areas of material flow and material handling engineering represent possible
applications for this function.
●
Regardless of the frames sent cyclically, a user can also send a message by pressing a
button.
●
This provides information on the operating status of the tag.
Note
For more detailed information, please refer to the AeroScout documentation
(www.aeroscout.com).
The tag sends its data as AeroScout frames. The tags and the access points communicate
in the 2.4 GHz band.
If the WLAN interface of the access point receives the AeroScout frame, this is converted
into a UDP datagram. The device forwards the UDP datagram along with the information
about the signal strength (RSSI) to a PC. The AeroScout Engine runs on the PC and
evaluates the received information.
