What requirements must be fulfilled and what should I watch out for when executing Routing?

  • Entry
  • Associated product(s)

The following requirements must be fulfilled for the "Routing" function with SIMATIC S7 modules via MPI, PROFIBUS and Industrial Ethernet connections:

Software requirements:

  • MPI and PROFIBUS connections:
  • At least STEP 7 V5.0+SP1, however a current version of STEP 7 is recommended.
  • For the Softnet PROFIBUS cards (CP 5411 (ISA), CP 5511 (PCMCIA), CP 5611 (PCI), CP 5611 (on board)) you don't need any other drivers, because they are provided by STEP 7.
  • For the Hardnet PROFIBUS cards (CP 5412(A2) (ISA), CP 5613/5614 (PCI)) you need the associated drivers from the SIMATIC NET CD.
  • Industrial Ethernet connections:
  • At least STEP 7 V5.0+SP1, however a current version of STEP 7 is recommended.
  • With CP1612/ CP1512 ,CP1515 and commercially available network cards you need a current release of the SIMATIC NET Softnet IE PG driver (at least Softnet IE PG V3.1).
  • With CP1613 and CP1413 you need the products SIMATIC NET IE PG 1613 and SIMATIC NET IE PG1413 respectively.
  • For implementation of a TS Adapter:
  • TeleService S7 V5.0 or higher.

Hardware requirements:

  • You need routing-compatible modules. Refer to Entry ID 584459 for routing-compatible modules, or take them directly from the hardware catalog of the STEP 7 Hardware Configuration.

    Fig. 01

    You still need one of the Online CPs mentioned under "Software requirements" or the TS Adapter V5.0 or a PC Adapter V5.0.


  • The last module that is to be addressed via the routing function does not have to be routing-compatible.
  • If you wish to route via an S7 CPU which is configured as a PROFIBUS DP slave, you have to activate the "Test, Commissioning, Routing" option in the HWCONFIG > DP interface properties > "Operating Mode" tab. You can also find this information in the STEP7 Online Help ("Operating Mode" tab).

Configuration procedure:
You must configure all the stations that lie between the Start device and the target device in one STEP 7 project.

No. Procedure
1 Insert a station of the type "PG/PC".

Fig. 02
2 Configure all the physically available network connections (MPI, PROFIBUS, Industrial Ethernet) in NETPRO or in the HW Config. This also applies for networks that are not directly in the path, but are connected to the route stations. This does not mean that you must use all the interfaces available. You must only configure the communication connections that are also physically available.

3 Open the Properties of the "PG/PC station" by double-clicking the PG/PC object.
4 Switch to the "Interfaces" tab and create a new node ("New" button). From the list that is displayed select the type of your node and acknowledge with "OK".
5 From the next window you select the network that is physically connected to your PG/PC. If you have not yet configured a network, then you must do it now.
The "PG/PC station" must be given the same address as set in the program "Set PG/PC interface" (also applies for CP 1413 and CP 1613).
6 Switch to the "Assignment" tab and assign the Routing entry point to your PG/PC.
First you select the node in the "Configured Interfaces:" pane and then in the second pane you specify the CP or the PC Adapter with the relevant network identification via which you want to go online.

7 Save and compile your network configuration.
8 Transfer your configuration into the CPU.
9 Create an online connection via the offline project.
This cannot be done via "Accessible Nodes".

Sample configurations:

  • Routing with modem and TS Adapter

  • Routing with ISDN Router:
