3.2.7 Routing
Properties
STEP 7 V5.1 + SP4 or higher allows you to access your S7 stations on all subnets with your
PG/PC, for example, to
• download user programs
• download a hardware configuration, or
• perform debugging and diagnostic functions.
Note
If you use your CPU as I-slave, the routing function is only possible when the
DP interface is switched to active IN STEP 7, set the Test, Commission Routing check
box on the properties dialog of the DP interface. For detailed information, refer to the
Programming with STEP 7 manual, or directly to the STEP 7 Online Help
Routing network nodes: MPI - DP
Gateways between subnets are routed in a SIMATIC station that is equipped with interfaces
to the respective subnets. The figure below shows CPU 1 (DP master) acting as router for
subnets 1 and 2.
