From this graphic representation, you can also activate all the functions for
networking and configuring connections with the Ethernet CPs.

Organization in a Multiproject
If you use the multiproject form of organization, this has the following effects when
creating subnets.
You create subnets initially in the subprojects as described above. To be able to
network S7 stations, you will, for example, need to create a suitable subnet of the
type Industrial Ethernet in each subproject.
If this is physically a subnet that extends beyond the boundaries of the subproject,
you should first merge the subnets before configuring the communication
connections between the S7 stations.
If you do not merge the subnets, NetPro assumes that you are connecting the
subnets via routers and displays warning messages to this effect.
Properties of Merged Subnets (Multiproject)
When you merge subnets, transferable subnet properties such as the subnet ID of
the master subnet will be transferred to the other subnets of the group.
Some parameters relate specifically to a subproject and remain unchanged; these
include, for example, descriptive parameters such as the name, author, and any
comments.
