Routing

Definition
The routing function enables you to attach a PG/PC at any point in the network and establish
a connection to all drives accessible via gateways.
Accessing drives in a DP(DRIVE) subnet from a PG/PC
Test, diagnostic and parameterizing functions can be routed via the MPI/DP interface (X1) to
the DP(DRIVE) subnet with the Technology CPU.
The Technology CPU provides a certain number of connection resources for routing. These
connections are available in addition to the S7 connection resources.
The number of routing connections can be found in the Technical Specifications.
Network gateway
Gateways between subnets are routed in a SIMATIC station that is equipped with interfaces
to the respective subnets. The figure below shows the Technology CPU (DP master) acting
as router for subnets 1 and 2.
