Changing the placeholder resolution

There are two ways to set the library to which a placeholder should be resolved:

via the Placeholder dialog
via the Properties window

You can use the placeholder dialog to set all placeholders in the project, that is, both the placeholders that are directly integrated at application level and the placeholders that are used within referenced libraries.

The properties window can only be used to set the placeholders available at application level.

Possibility 1: Via the Placeholder dialog

Open the Placeholder dialog.
Double-click the field in the Library column that belongs to the row of the placeholder whose resolution you want to change.
A dialog through which you can select the desired library opens below the selected row. The dialog offers the following options.

Reset to default	This command is only available for placeholders that cannot currently be resolved according to their default resolution. This is the case, for example, if you add a Beckhoff placeholder and change the placeholder resolution to another library version. Using the command Reset to default you can resolve such a placeholder in accordance with the default resolution again. In doing so the library of the same name is usually selected with "Always newest"/"*".
Other versions of the selected library	If this area displays the library version to which you want to resolve the placeholder, you can click this version. The placeholder is then resolved to the same library, but to a different version of this library.
Other library	If you want to resolve a placeholder to another library, you can open a dialog via Other library, in which you can select the desired library from all installed libraries. If you activate the Display all versions option in this dialog, you can not only specify the desired library, but also select a specific version of this library.

Possibility 2: via the Properties window

Open the Properties window.
Select a placeholder in the project tree below the References node.
The Properties window shows the properties of this placeholder.
The Resolution field provides a drop-down list containing the available versions of the previously selected library and the entry "...".

If this area displays the library version to which you want to resolve the placeholder, you can click this version. The placeholder is then resolved to the same library, but to a different version of this library.
If you want to resolve the placeholder to another library, you can open a dialog via “…”, in which you can select the desired library from all installed libraries. If you activate the Display all versions option in this dialog, you can not only specify the desired library, but also select a specific version of this library.
