Example: PG access across network boundaries (routing)
With a programming device you can access all modules across network
boundaries.
Prerequisites
• You must be using STEP 7 Version 5.0 or later.
• 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.

Information on routing is found in the ...
• CPU Manual.
• In the Communication with SIMATIC manual.
To use the routing function, you must always configure your CPU 31xC as master;
this feature is not available with an I-Slave configuration!
