nergy or Bluetooth Smart as of Bluetooth version 4.0.
In a hard-wired system, wireless communication is primarily designed to provide
a second interface for communicating with the device (e.g., for con
fi
guration and diag-
nostics).
ZIEHL-ABEGG provides the "ZAset mobile" app for the use of mobile devices via Blue-
tooth Low Energy. The app requires Android devices from version 4.3 onwards and iOS
devices from version 8. onwards. The app can be downloaded from Google Play Store
or iTunes.
The wireless communication uses the MODBUS protocol (MODBUS-TCP). The Blue-
tooth addressing takes place via the Bluetooth address.
The Bluetooth scan automatically detects all devices within range. The app can then
connect with these devices via the Bluetooth address.
The MODBUS address is read and displayed as part of a Bluetooth scan. This means
that you can also identify the device via its MODBUS address if one has been assigned.
Therefore, it is a good idea to assign a MODBUS address even if the MODBUS network
is not in use.
You can change the MODBUS address via the app in the device "IO Setup"; see the
"Bus Address" parameter. Then apply the same procedure to the next device.
Access code (0
–
9999)
Unlike in the case of RS-485 communication, you can protect your device with an access
code (0 - 9999) for wireless communication via the AM-STICK-WB.
During installation, it is essential to assign a dedicated secure access code to a Blue-
tooth device or an associated group of Bluetooth devices.
The factory setting is

. An access code with the value

deactivates the access
protection function.
"
If the access code is deactivated, the app prompts you to turn it on.
"
If the access code is set to the factory setting, the app will prompt you to change it.
Information
You must switch off or reset the device to activate the access code after changing it
manually. You can change the access code via the app in the device "Controller Setup";
see the Network Key parameter.
