No. Integration of a WinCC flexible project in STEP 7
1

Proceed as follows to integrate a WinCC flexible project in STEP 7.

  1. Open the WinCC flexible configuration.
  2. Select the menu command "Project > Integrate in STEP 7...".
    The "Integrate in STEP 7 projects" dialog opens.
  3. Select the relevant STEP 7 project in the dialog box.
    If the project you desire is not listed, navigate via the search field to the folder in which the STEP 7 project is located.
    Integration is executed once you select the STEP 7 project.

Note
The STEP 7 project does not have to be open for this.

Parameterization of the connection / communication partner
In the "Stand alone" mode you have set all the connection parameters to the controller manually.
In the "Integration" mode you can define the station via which the communication partner is to be addressed using the selection menu. The addresses are then transferred automatically.
Furthermore, using this measure with the tags, you can access the symbolic connection.

  1. Open the STEP 7 project in which you previously integrated the WinCC flexible project.
  2. Mark the HMI station and double-click to open the "Configuration" of the HMI station.
  3. Open the "Properties" of the operator panel's interface and define the interface and address.

  1. Switch to the WinCC flexible configuration and open the "Connections" in the project tree via "Communication > Connections".
  2. Select the relevant station under the "Station".
    The "Partner" and all the other parameters are transferred automatically.

This completes integration of the WinCC flexible project.

Possible causes of error when it is not possible to integrate a WinCC flexible project in STEP 7.

If the function for integrating the WinCC flexible project is grayed out or not available, this might be due to the following reasons.

  • You must install WinCC flexible Integration, because WinCC flexible was installed before STEP 7.

    Instructions
  1. Via the Control Panel you call the WinCC flexible Setup and change the installation.
    Control Panel/Software/SIMATIC WinCC flexible  Button: Change/Delete
  2. Activate the integration of STEP 7.
    The "WinCC flexible Integration" and "STEP 7" check boxes must be checked.
    (You need the WinCC flexible installation CD for this.)

Note
If you install the STEP 7 software before installing WinCC flexible, the WinCC installation routine recognizes the installation of STEP 7 and automatically installs support for integration in STEP 7.
If making a custom installation of WinCC flexible, make sure to activate the option "Integration in STEP 7".

  • If STEP 7 is already installed and you make an update for STEP 7, e.g. by installing a Service Pack, then you have to reinstall STEP 7 Integration in WinCC flexible.

    Instructions
  1. Via the Control Panel you call the WinCC flexible Setup and change the installation.
  2. Deactivate the integration of STEP 7.
  3. Then restart the Setup and activate the integration of STEP 7.
    (You need the WinCC flexible installation CD for this.)

You cannot integrate Micro Panels, e.g. a TP177micro, into STEP 7.
