Set Up Multiple SNCP Networks
Multiple logical Networks
The Workbench also supports multiple redundant networks. This type of network
configuration provides a dedicated logical network (which can be physically redundant)
to bindings only, to prevent Safety Data from being combined with none Safety Data.
The SNCP_Workbench network is the one used by the Workbench to
communicate with target while additional networks, such as the SNCP_1 network
shown, are used specifically for transporting variables over bindings.
1) Set up a second SNCP network and connect the resources to that network.
2) Enter the IP Addresses using the same subnet for each controller on the same
network:

SNCP_Workbench connection: IP Address 1 = 10.75.104.99 and
IP Address 1 = 10.75.104.100

SNCP_1 connection: IP Address 2 = 10.44.200.10 and IP Address 2 =
10.44.200.20.

This configuration increases the options for the configuration of bindings, two
networks are now available when a variable binding is created. The SNCP
binding driver will only send the bound variable over the selected network(s).
This means if variable is bound over the SNCP_1 network only, and that
network fails, the data for that variable will not be received by the consumer.
However, you can select both networks to configure a redundant dual
network.
