With a programming device you can access all modules across network
boundaries.
Requirements
• You are using STEP 7 Version 5.0 or higher.
Note: for STEP 7 requirements on utilized CPUs, refer to technical
specifications.
• You must assign the PG/PC to a network in your STEP 7 project (SIMATIC
Manager, assigning a PG/PC).
• The network boundaries must be bridged by modules with routing capability.
• After having configured all networks in NETPRO, you have initiated a new
compilation for all stations and downloaded the configuration to every module
capable of routing. This also applies to all changes made in the network.
Thus, every router knows all possible paths to a target station.

If these CPUs are operated as I-slaves and you want to use the routing function,
you must activate the Commissioning/Test Mode functionality in the Properties -
DP Interface for DP Slave in STEP 7.
