Example Of Pg Access Across Network Boundaries (Routing) - Siemens SIMATIC S7-300 Hardware And Installation Manual

Example: PG access across network boundaries (routing)
With a programming device you can access all modules across network
boundaries.
Requirements
• You must be using STEP 7 version 5.0 or later
You must be using STEP 7 version 5.1 or later + SP 4 (only for CPU 31xC, 312,
314 and
315-2 DP with 6ES7315-2AG10-0AB0)
• 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.

Note
For the CPU 31xC-2 DP, 315-2 DP only:
If you wish to use the routing function for these CPUs, you must activate the
Commissioning / Test mode function under the properties of the DP interface for
DP slave in STEP 7.
