5 SETTINGS
The original standard IEC 62439-3 (2010) was amended to align PRP with the High-availability Seamless Redundancy
(HSR) protocol. To achieve this, the original PRP was modified at the cost of losing compatibility with the PRP 2010 ver-
sion. The revised standard IEC 62439-3 (2012) is commonly referred to as PRP-1, while the original standard is PRP-0.
The UR relays support only PRP-1.
The relay implements PRP on two of its Ethernet ports, specifically Port 2 and 3 of the CPU module. Use the previous sec-
tion (network port configuration) to configure PRP.
PRP is purchased as a separate option. If purchased (valid order code), PRP can be enabled in configuration through a
setting available on the network configuration menu, REDUNDANCY, which already has the capability of enabling failover
redundancy. The options on this setting must be changed to accommodate two types of redundancy: failover and PRP.
When REDUNDANCY is set to either failover or PRP, the ports dedicated for PRP (Port 2 and 3) operate in redundant
mode. In this mode, Port 3 uses the Mac, IP address, and mask of Port 2.

A default route and a maximum number of six static routes can be configured.
The default route is used as the last choice when no other route towards a given destination is found.

MESSAGE
Configure the network IP and subnet settings before configuring the routing settings.
ADDING AND DELETING STATIC ROUTES
Host routes are not supported at present.
The routing table configuration is available on the serial port and front panel. This is a deliberate decision, to avoid loss of
connectivity when remotely configuring the UR.
By default the value of the destination field is 127.0.0.1 for all static routes (1 to 6). This is equivalent to saying that the
static routes are not configured. When the destination address is 127.0.0.1, the mask and gateway must be also kept on
default values.
By default, the value of the route gateway address is 127.0.0.1. This means the default route is not configured.
To add a route:
1. Use any of the static network route entries numbered 1 to 6 to configure a static network route. Once a route destina-
tion is configured for any of the entries 1 to 6, that entry becomes a static route and it must meet all the rules listed in
the next section, General Conditions to be Satisfied by Static Routes.
