With a programming device you can access all modules across network
boundaries.
Requirements
• You must use STEP 7, Version 5.0 or higher.
• 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 node.
This example illustrates routing beyond network limits with two MPI networks and
one PROFIBUS-DP network.
