TIA configuration

TIA project

Online device

Enables online browsing. When selecting this option, you have to specify the IP address and PLC type in the configuration panel.

Project name

Shows the currently selected TIA project.

Station name

Shows the currently selected station (PLC).

Select

This button opens the following panel where you can browse the available TIA projects.

The panel lists all TIA projects which were exported as zip file and stored on the host on which the driver is running under <WinCC_OA_Proj>/data/TIA_Projects.

Select the TIA project on the left side and the necessary station on the right side. Click OK to confirm the selection.

A click on the Export button opens the file selection dialog. Define a .txt file and confirm the selection. The browsed data is exported to the stated .txt file.

In case of changes to the TIA project (like adding new data blocks or variables), existing addresses will not be invalid. A new TIA export is only necessary if you want to use the changes in WinCC OA. To apply the changes to the driver you have to select the TIA project again.

If a new TIA project or station is selected the following panel is opened. If you tick the checkbox (see below) the configuration parameters are also applied automatically.
