How do you use WinCC flexible to transfer a project to an operator panel via S7 routing?
Introduction for S7 Routing
If you implement a router, you can establish a connection between different subnets. A SIMATIC station can act as a router if it has suitable interfaces.
The modules with communications capability (CPUs or CPs), which create gateways between the subnets, must support routing.
To transfer a WinCC flexible project, the WinCC flexible configuration computer must be connected to an MPI bus, PROFIBUS or Ethernet.
The operator panel to which the WinCC flexible project is to be transferred must also be connected to an MPI bus, PROFIBUS or Ethernet.
- Refer to a component's technical documentation to establish whether it supports routing.
Alternatively, open the component's object properties in NetPro or in HW Config. The "General" tab contains a brief description of the properties.
Information about which modules possess routing capability is also available in Entry ID: 584459.
- The requirements that have to be fulfilled to perform STEP 7 routing by means of a PG/PC station are given in Entry ID: 16620173.
- A routing connection for the transfer can also be established by means of multiple routing partners. Routing cannot be used as a means of transferring to PC-based operator panels (PC Runtime) with an activated station manager (Station Configuration Editor).
- In order to establish a routing connection, all the stations within a STEP 7 project must be configured and loaded.
- You must use NetPro to configure all the devices and subnets connected to the network.
S7 Routing MPI / PROFIBUS and Ethernet
Below is a list of the requirements and the supported HMI operator panels and the possible routes for S7 Routing are shown in Fig. 01.
- At least WinCC flexible 2005
- At least STEP 7 V5.3 SP2
- All panels including PC Runtime except PC Station with Station Configuration Editor
S7 Routing Ethernet with WinCC flexible 2008
The S7 Routing function was extended with WinCC flexible 2008. Below is a list of the requirements and the supported HMI operator panels and the possible routes for S7 Routing are shown in Fig. 02.
- At least WinCC flexible 2008
- At least STEP 7 V5.4 SP3
- You can use only the following devices for routing over the "S7 Ethernet" transfer channel:
- TP 177B 4"
- MP 177
- Mobile Panel 277
- MP 277
- MP 377
- Routing over Ethernet is not possible with WinCC flexible PC Runtime.
- In the case of routing by way of SIMOTION CPU 4.1.2, transfer of the configuration over S7 Ethernet does not work.
- Routing from MPI/DP to Ethernet is possible if MPI/DP has been selected in the Transfer settings.
S7 Routing Ethernet and WinCC flexible 2008 SP3
More devices were added to the S7 Routing function with WinCC flexible 2008 SP3.
Below is a list of the requirements and the supported HMI operator panels and the possible routes for S7 Routing are shown in Fig. 03.
- At least WinCC flexible 2008 SP3
- At least STEP 7 V5.4 SP3
- You can also use the following devices for routing over the "S7 Ethernet" transfer channel:
- OP 77B
- OP 177B
- TP 177B
- Mobile Panel 177
- OP 277
- TP 277

Example of S7 Routing with Ethernet
Fig. 01 shows a routing connection between the WinCC flexible configuration computer (network object: Stations > PG/PC) and operator panel "MP 377 15'' Touch" (network object): Stations > SIMATIC HMI station). The "SIMATIC 300(1)" programmable logic controller acts as a router.
Use NetPro to configure the routing connection between the devices involved.
You must assign the interface of the configuration computer. You can recognize the assignment by the yellow connection line to the subnet and by the yellow arrow in the station symbol.
The procedure for configuring a routing connection is described in Entry ID: 2383206.
- Open the HMI station in WinCC flexible.
- Select the menu command "Project > Transfer > Transfer Settings".
- Select the operator panel.
- Select the mode and check the "Enable routing" option box.
The mode must match the communication channel.
- In the "Next station" box, you select the bus type of the next and the last connection.
The network addresses of the next routing partner and destination device are displayed.
Any routing partners positioned between them are not displayed here.
- Transfer your project by clicking the "Transfer" button.
