Routing

2-8
When the configuration card is present, a default route and a maximum number of 6 static
routes can be configured. The default route is used as the last choice, if no other route
towards a given destination is found.
Path:
Setpoints > Device > Communications > Routing > Default Route
GATEWAY ADDRESS
Range: Standard IPV4 unicast address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the gateway of the default route to be used by IP traffic sent from the
relay, if no other route towards a given IP destination is found.
This setting is available only if the communications card is present.
Path:
Setpoints > Device > Communications > Routing > Static RT1 (2 to 6)
RT1 (2,3,4,5,6) DESTINATION
Range: Standard IPV4 network address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the destination IPv4 route. This setting is available only if the
communications card is present.
RT1 (2,3,4,5,6) MASK
Range: Standard IPV4 network mask format
Default: 255.0.0.0
This setting sets the IP mask associated with the route. This setting is available only if the
communications card is present.
RT1 (2,3,4,5,6) GATEWAY
Range: Standard IPV4 unicast address format (0.0.0.1 to 223.255.255.254)
Default: 127.0.0.1
This setting sets the destination IP route. This setting is available only if the
communications card is present.
ADDING AND DELETING STATIC ROUTES
Defaults:
Rule #1.
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 also be kept as default values.Rule #2.
By default, the value of the default route gateway address is 127.0.0.1. This means the
default route is not configured.
Adding a route:
Rule #3.
Use any of the static network route entries numbered 1 to 6 to configure a static
network route. Once a route destination 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 following section
under "Important Notes".
Rule #4.
To configure the default route, enter a default gateway address. A default gateway
address configured must be validated against Rule #5, the next rule.
