    Project transfer via S7 routing

    Introduction

    WinCC flexible supports the download of a WinCC flexible project from a configuration computer to an HMI device across different subnets. To establish a connection between different subnetworks, a router must be interposed. In this case, a SIMATIC station can act as a router if it has appropriate interfaces to the different subnetworks. Modules with communication capability (CPUs or CPs) used to establish gateways between the subnetworks must have routing capability.

    To transfer a project, the WinCC flexible Engineering Station must be connected to an MPI bus, PROFIBUS or Ethernet. The HMI device to which the project is to be transferred must also be connected to an MPI bus, PROFIBUS or Ethernet.

    The routing connection for the transfer is independent of the connection configuration between the HMI device and the automation device in your WinCC flexible project. The connection described in this chapter is only for the transfer of a WinCC flexible project to an HMI device over a routing connection.


    Note

    Please see the technical documentation for the respective component to determine whether a component can be routed. Alternatively, open the object properties for the component in NetPro or in HW Config. The "General" tab contains a short description of the properties.

    OP 73, OP 73micro, OP 77A, TP177A und TP 177micro HMI devices do not support S7 Routing for the transfer of projects.



    Routing connection for the transfer operation

    To create a routing connection, all stations must be configured and loaded within a STEP 7 project. The target device cannot be initialized over the routing connection.


    Figure: Illustration of a routing connection for the transfer operation

    In the above figure, a routing connection was established between the "WinCC flexible ES" WinCC flexible Engineering Station and the "Operator Panel 8 - OP77B" HMI device. The "SIMATIC 300-Station 1" automation device functions as the router. You configure the transfer connection between the concerned devices with NetPro. The interface of the configuration computer must be assigned. The association is indicated by the yellow connection line to the subnetwork and the yellow arrow in the symbol of the station. After the configuration in NetPro, save and recompile the project.


    Figure: Routing over several stations

    Requirements for routing over several stations:

    • The WinCC flexible Engineering Station must be connected to an MPI bus, PROFIBUS or Ethernet.
    • The HMI device to which the transfer operation should take place must be connected to an MPI bus, PROFIBUS or Ethernet.

    Starting the transfer in WinCC flexible

    After configuration in STEP 7 is complete, open the HMI station in WinCC flexible. To trigger the transfer, select the "Project ► Transfer ► Transfer Settings" menu command.


    Figure: Transfer settings

    "MPI/DP" must be set in the "Mode" field.

    The "Enable routing" box must be checked.

    The "Next station" field shows the bus type of the next and last connection and the network address of the next routing partner and the target device. Any potential intermediate routing partners are not shown here.

    If you click the "Transfer" button, the transfer will start right away.

    The routing settings are only made available, if you have set the bus type to "MPI/DP" of "S7Ethernet" under Mode. If the settings for the routing are not displayed, the system cannot identify a persistent routing connection. Check the settings and the network addresses of the concerned stations. The configured parameters must match the configuration of the stations on the system.

    A routing connection for the transfer can only be established in an integrated project.


    Note

    The routing transfer to PC-based HMI devices with enabled station manager is not possible.
