11 Networking Stations
11.1 Networking Stations within a Project
Context: Network Configuration and STEP 7 Projects
Subnets lie directly beneath a project in the object hierarchy and can therefore only
be managed within a project. You can, however, connect nodes together that were
configured in different projects.
If possible, you should create and configure nodes that you want to connect in
networks in the same project.
Subnets and Stations
You can create the subnets and stations in a STEP 7 project and then configure
the stations for communication very easily.
As a result of the different tasks of the stations or the fact that the plant has
increased in size and scope, it may be necessary to run a number of subnets.
These subnets can also be managed in one project. A station can be assigned to a
number of subnets by assigning the communication nodes (for example, CPs)
accordingly.
