Note
Devices with two Ethernet ports
With devices that have two Ethernet ports, only port P1 should be used for the PNIO
configuration because LLPD frames can only be sent and received via port 1. They are
blocked at port 2 and are also not forwarded between the ports. This applies to the following
devices:
• SCALANCE W786-2 SFP
• SCALANCE W774-1 RJ-45
• SCALANCE W774-1 M12 EEC
• SCALANCE W734-1 RJ-45
SCALANCE W700 and STEP 7
The Ethernet interface can be configured in STEP 7 if the following requirements are met:
● STEP 7 V13 Update 3 with HSP0107 or
● STEP7 version 5.5.4 with GSDML version 2.31
The diagnostics functions can also be used. The WLAN interface cannot be configured with
STEP 7.
PNIO for client devices
If a client is to be used as a PNIO device, the MAC address of the client must be specified as
follows (MAC Mode):
● Own
In the network beyond the device, only IP communication and no PNIO is possible.
● Layer 2 Tunnel
The client and the devices downstream from it can be used as PNIO devices.
Note
If "Automatic" or "Manual" is configured as the MAC mode for a client, this device cannot
be used as a PNIO device.
