1.7.6 Network/Project Variant: Connections between Subnets
(TCP/IP)
Configuration of the System
If connections are required to stations on network structures connected by routers
due to the differing tasks of the stations or the large span of the network, the
stations in the other project can be reached by configuring “Other Stations”.
