c) ETHERNET NETWORK TOPOLOGY
The three independent UR ports do not have routing capability and work only on local subnets for the switched network
topology. End nodes can communicate with each other using all supported protocols of the UR family on a local network. In
a routed network, it is recommended to upgrade the UR device used to 7.1x or higher where routing capability through
static route settings has been introduced.
When using more than one Ethernet port, configure each to belong to a different network or subnet using the IP addresses
and mask, else communication becomes unpredictable when more than one port is configured to the same subnet.
Example 1
IP1/Mask1: 10.1.1.2/255.255.255.0 (where LAN 1 is 10.1.1.x/255.255.255.0)
IP2/Mask2: 10.2.1.2/255.255.255.0 (where LAN2 is 10.2.1.x/255.255.255.0)
IP3/Mask3: 10.3.1.2/255.255.255.0 (where LAN3 is 10.3.1.x/255.255.255.0)
Example 2
IP1/Mask1: 10.1.1.2/255.0.0.0 (where LAN1 is 10.x.x.x/255.0.0.0)
IP2/Mask2: 11.1.1.2/255.0.0.0 (where LAN2 is 11.x.x.x/255.0.0.0)
IP3/Mask3: 12.1.1.2/255.0.0.0 (where LAN3 is 12.x.x.x/255.0.0.0)
Example 3 — Incorrect
IP1/Mask1: 10.1.1.2/255.0.0.0
IP2/Mask2: 10.2.1.2/255.0.0.0
IP3/Mask3: 10.3.1.2/255.0.0.0
This example is incorrect because the mask of 255.0.0.0 used for the three IP addresses makes them belong to the same
network of 10.x.x.x.
Single LAN, No Redundancy
The topology shown in the following figure allows communications to SCADA, local configuration/monitoring through
EnerVista, and access to the public network shared on the same LAN. No redundancy is provided.
