PROFINET networking via Bluetooth
®
Figure 26: ETHERNET Bridge
This example describes how to connect a PROFINET IO device and a
PROFINET PLC over
Bluetooth
®
using two Wireless Access Points and Easy
Config.
The Wireless Access Points will be configured with PROFINET optimization,
which means that PROFINET messages will have priority over TCP/IP frames.
See the respective documentation for the IO device and PLC on how to configure
them for PROFINET communication.
Configuration
1.
Reset both Wireless Access Points to the factory default settings.
2.
Connect Wireless Access Point 1 to the IO device and Wireless Access
Point 2 to the PLC.
3.
Set Wireless Access Point 1 to Easy Config
Mode 4
.
This unit will now be discoverable and open for automatic configuration.
4.
Set Wireless Access Point 2 to Easy Config
Mode 8.
This unit should now automatically discover and configure unit 1 as a
Bluetooth
®
client, and configure itself as an access point. Both units will be optimized for
PROFINET.
The IO device should now be able to communicate with the PLC as if using a
wired connection.
Adding More Devices
Up to 6 additional clients can be added by repeating the procedure. Each new
client will be assigned the next free IP address in the current subnet.
Note the IO cycle update time!
The IO cycle update time for each IO device must be set to ≥ 64 ms
