Communication via Ethernet CPs in S7 Stations
Variants
Before configuring networks with STEP 7, you should be aware of the various
configurations possible in the STEP 7 project. The following configurations are
typical for stations networked with CPs:
Variant (examples)
1 1 subnet – 1 project
2 Additional SIMATIC S5 stations and stations with equipment of other vendors
3 2 or more subnets – 1 project
4 1 subnet – more than one project
5 More than one subnet – more than one project
6 Internetwork connections (TCP)
These variants will be used as a basis to illustrate how real configurations can be
created in STEP 7 projects.
