All packets sent via this network interface will use the source address and – in case of VLAN interfaces – VLAN ID as specified by this interface to generate a packet. All packets received via this network interface will use – in case of unicast communication – the destination address and – in case of VLAN interfaces – VLAN ID as specified by the interface to filter incoming packets.

When using PubSub, each PubSubConnection as defined by the PubSubConnectionDataType in Part14 contains the address variable of type NetworkAddressDataType. If the networkInterface String of the NetworkAddressDataType matches the BrowseName of one Object in the NetworkInterfaces folder, it links the transmission or reception and the network interface. An example is shown in Figure A-3.
