4.11 Planning subnets
S7-300, CPU 31xC and CPU 31x: Installation
4-60 Operating Instructions, Edition 08/2004, A5E00105492-05
Requirements
• CPUs as of Firmware 2.3.0 (for example CPU 315-2 PN/DP)
• STEP 7, as of Version 5.3 + Service Pack 1
Reference
For information on PROFINET, refer to:
• the
System Description PROFINET
• in the programming manual
From PROFIBUS DP to PROFINET.
This manual also
provides a comprehensive overview of the new PROFINET blocks and system status
lists.
4.11.4 Routed network transitions
Example: PG access to remote networks (routing)
A CPU with several interfaces can also serve as a router for intercommunication with
different subnets. With a PG you can access all modules on local and remote networks.
Requirements:
• STEP 7 Version 5.0 or higher.
Note: For STEP 7 requirements with respect to the CPUs used, refer to the technical
specifications.
• Assign the PG/PC to a network in your STEP 7 project (SIMATIC Manager, assigning a
PG/PC).
• The various networks are interconnected using modules with routing functions.
• After you configured all networks in NETPRO, initiated a new compilation for all stations,
and then download the configuration to all modules with routing function. This also
applies to all changes made in the network.
All routers therefore know all paths to a destination station.
