Configuration
At a Glance
In an intermediate station, the management of several network couplers requires a configuration phase in order to distribute the functional characteristics to the various network entities.
126
NOTE: Multi-network routing information is constructed at the station level at the time of configuration of each bridge. No consistency check is done on routing data for the same network architecture.

Configuration of X-Way Routing
Configuration of Multi-Network Services
At a Glance
In a station that supports various network modules, each network connection point is considered as an address for the station. When configuring each module, it is necessary to define the list of network numbers that are accessible for each connection point.
Depending on the processor selected during hardware configuration, a bridge station can only manage 3 or 4 network modules. The table will therefore have a maximum of 4 elements.
Illustration
A specific screen allows entry of routing data for all the network modules of a station.

Used:
for the unshaded Logical Network zone, to enter the list of networks accessible by this module,
for the shaded Logical Network zones, to display the list of networks accessible by these modules.
Used to select the networks accessible by a module configured as a bridge.
A list of numbers from 1 to 127 shows the networks available for a connection point. Each network number selected as being accessible is removed from the list of available networks in order to avoid configuration errors.

Configuring an X-Way Router Module
At a Glance
Before configuring the module as an X-Way router, the station’s logical networks must be created.
Procedure
The following procedure is used to access, and then configure the station’s module as an X-Way router.
Step
1
Action
Open the Communication tab in your project browser and in the Routing
table tab, click the X-Way table tab.
Result: The following window appears.

Step
2
Action
Double-click the highlighted field in order to configure the first network.
Result: The Selection of accessible networks window appears.

6
Double-click the number of the required network from the Available networks scroll list.
Result: The network number is assigned in the Access networks scroll list.
Perform operation 3 as many times as necessary to define all the networks accessible by the module.
Once finished, proceed to step 5.
Confirm the selection by clicking OK.
Confirm the configuration of the X-Way router by closing the window or clicking the Enable button in the toolbar.

Double-click the numbers of the accessible networks to be removed (left column).
Result: The network number is reassigned in the Available networks scroll list.
Confirm the selection by clicking OK.
Confirm the router configuration.

Each station must be configured in order to define the list of accessible networks.

Configuration of Station R1
The module at slot 2 can only access network 12.
The module at slot 4 can only access network 1 and 11.
The module at slot 5 can access networks 13 and 21.
The bridge configuration of the station is therefore as follows:
Configuration of Station R2
The module at slot 0 can only access network 11.
The module at slot 5 can access networks 1, 12, 13 and 21.
The bridge configuration of the station is therefore as follows:

35010500 10/2014
Configuration of Station R3
The module at slot 0 can access networks 13, 12, 1 and 11.
The module at slot 5 can only access network 21.
The bridge configuration of the station is therefore as follows:
Configuration of X-Way Routing
Messaging
To use the communication function (see Unity Pro, Communication, Block Library) such as
Read_VAR for ethernet exchange between stations, configure the TCP/IP Messaging in the
Ethernet network configuration (see Premium and Atrium Using Unity Pro, Ethernet Network
Modules, User Manual) screen. In the Messaging tab, for each exchange set the IP address and target XWay address.
For example if station R3 needs to communicate with station B, in R1Messaging tab:
set the R2 IP address (139.255.255.4) in the field IP address, and set the B XWay address (11.4) in the field XWay address.
The following illustration shows the R1 Messaging tab:
For another example if station B needs to communicate with station A, in R2, Messaging tab: set the R1 IP address (139.255.255.5) in the field IP address, and set the A XWay address (21.7) in the field XWay address.

Examples of Partial Routing
At a Glance
When configuring a module as a bridge, it is possible to assign to it only a part of the available networks, instead of all of them. This selection is used to define a partial routing.
Illustration
Each station must be configured in order to define the list of accessible networks.

Configuration of X-Way Routing
Configuration of Station R1
The module at slot 2 is not involved in the routing of data.
The module at slot 4 can access networks #1 and #11.
The module at slot 5 can access networks #13 and #21.
The bridge configuration of the station is therefore as follows:
Configuration of Station R2
The module at slot 0 can only access network #11.
The module at slot 5 can access networks #1, #13 and #21. Network #12 is inaccessible.
The bridge configuration of the station is therefore as follows:
