EXAMPLE

The following example shows how to add columns to the project view. The script contains a dpConnect() call. Via the call columns are added to the project view of GEDI. Proceed as follows:

• To execute the script, create a dyn_string data point as shown in the figure below.

• Save the following script as the projectView.ctl under WinCC_OA_Proj/scripts/gedi/projectView.ctl. and restart GEDI. You can also copy the script "projectView.ctl." from the WinCC OA version directory and replace the code by the following code.

• Add column names to the data point via PARA as shown in the figure below.

• Columns are first deleted viapvRemoveAllUserColumns() if user-defined columns exist.Then the columns are added to GEDI.
