Ethernet Forwarding
When enabled, the "Ethernet Forwarding" feature will forward all Ethernet packets
destined for a host (3rd Party Device) connected to one of the AADvance’s Ethernet
ports along with any broadcast and multicast Ethernet traffic. Incoming messages on
the other port will be forwarded directly to the second. The forwarded messages will
be unaltered by the AADvance controller.
This feature can be enabled using the AADvance Discover utility. Packets intended for
the AADvance itself (i.e. the destination MAC address of the packet matches the
processor’s receiving port MAC address) as well as broadcasts and multicasts are still
sent to the AADvance application as normal.
Note: The Ethernet network carrying Safety Data on a Safety application is considered
to be a black channel, therefore, it is unaffected by this function. However, by
implementing Ethernet Forwarding you may be forwarding non-safety data onto a
safety network and could effectively bridge a safety and non-safety segregated network
through the AADvance.
