S7 routing for CPU-CPU communication
You have the option of setting up an S7 connection from a CPU to another CPU via different
subnets (PROFIBUS and PROFINET or Industrial Ethernet). The procedure is described
based on examples in the section S7 communication (Page 112).

Using S7 routing
For the CPU, select the PG/PC interface and the S7 subnet in the "Go online" dialog of
STEP 7. S7 routing is performed automatically.
Number of connections for S7 routing
The number of connections available for S7 routing in the S7 routers (CPUs, CMs or CPs)
can be found in the technical specifications in the manuals of the relevant CPU/CM/CP.
