Transponder operation - frequency bands
Note
For transponder operation with automatic zone detection, the 2.4 GHz band will be used exclusively by the Mobile Panel
IWLAN.
WLAN operation requires the 5 GHz band (IEE 802.11a).
It is not possible to operate other RFID systems in the 2.4 GHz band at the same time (z. B. MOBY U or MOBY R systems).
Access Point - wireless communication
Note
Communication with more than one access point to cover larger WLAN areas is not possible without interruption.
For wireless Ethernet-based communication, for example, with PROFINET IO, HTTP, Sm@rtAccess, Sm@rtService and
OPC, the end user is responsible for the security of the data network. The secure operation of the HMI device cannot be
guaranteed under all circumstances. Interference from outside the wireless network can cause an overload of the HMI
device, for example.
The "Storm Threshold" function in the Siemens Access Point SCALANCE must be selected. This option has to be selected
to ensure stable plant operation when the load on the network is high. The following settings have to be made for broadcast
message frames:
●
Address Threshold: 255
●
Wireless: 255
PROFINET IO
Note
To improve the safety of your application, request the life sign bit in your CPU application.
