Defining the Project Structure

The project structure is composed of page and device structures. When regarded separately, the device structure is also composed of further individual structures, for example "General devices", "Terminal strips", "Cables", "Black boxes", etc.

Each of these structures can be separately determined by means of identifier schemes. The use of the various identifier blocks is defined in these schemes, which you fill with the appropriate structure identifiers. EPLAN provides pre-defined identifier schemes. In addition to this, you can define user-defined identifier schemes for your own project structures.

When creating a project, its page and device structure is determined by the selected basic project. In the project properties dialog you can also change page and device structure subsequently. The page structure can however only be changed later under specific conditions at a project with pages.

Precondition:

You have created a project and selected it in the page navigator.

Select the following commands: File > Information > Command group Project properties > Structure.
Select one of the available identifier schemes from the Pages drop-down list, or click [...], in order to specify a user-defined page structure in the subsequent Page structure dialog.
Select one of the available designation schemes from a drop-down list for a device type, for instance General devices, or click [...] in order to specify a user-defined device structure in the following Device structure dialog.
If you would like to use sub-identifiers, use [Other] to branch to the Extended project structures dialog and select a Separator there.
Click [OK].

Note:

In the Backstage view Information, changes of the project structure are saved as soon as you switch to another tab or leave the Backstage view. In this case a message is displayed and you can apply the modifications or undo them, as required.
If inconsistent data would occur due to modifications, additional messages are displayed which inform you about the occurred incorrect state. You can then either keep editing the project structure and correct the error or undo the modifications.
