Editing Identifiers

Different options for editing structure identifiers are available. These can be activated either through the popup menu or by using the buttons.

Move identifiers

Moving of structure identifiers is necessary if the order of identifiers in the page navigator is to be changed. The order of pages in the page navigator is oriented to the order in the Position column.

Precondition:

You have opened a project which uses structure identifiers, for instance "Higher-level function" and "Mounting location" in the project structure.

Project data > Structure identifier management
In the Identifiers - <Project name> dialog, select the identifier block (left area of the dialog) that you want to edit.
Select the structure identifier to be moved in the List tab. Multiple selection is possible here.
Click one of the buttons (Move down) or (Move up).

The selected lines are moved one position down / up.
Or click one of the buttons (Move to the beginning) and (Move to the end).

The selected lines are moved to the top / to the end of the table.
Click [Apply].
Answer the prompt.

Note:

Movement is also possible in the List tab by holding the left mouse button down; here, however, the entire row and not just a single column must be selected. The selected structure identifiers can then be dragged over several rows into a new position. A moving rectangle, which hangs on the mouse pointer, indicates that this function is active. A red line indicates the two other structure identifiers between which the row will be inserted as soon as the mouse button is released.

Rename identifiers

This editing function makes it possible to change an existing structure identifier without changing its position in the order of structure identifiers.

Precondition:

You have opened a project in which identifier blocks are used in the project structure, for instance "Higher-level function" and "Mounting location".

Project data > Structure identifier management
In the Identifiers - <Project name> dialog, select the identifier block you want to edit.
In the List tab, click in the Designation field of the structure identifier you want to rename.
Enter the new designation.
Click [Apply].
Answer the prompt.

Using this function, not just the pages but also the structure identifiers are changed in the devices. Any existing formatting (e.g. a line break) remains unchanged.

Tip:

In the page navigator the structure identifiers can be directly renamed by double-clicking the identifier to be renamed and entering the new designation. This changes the structure identifier of all pages below the selected node in the tree, whereby the new structure identifier then affects the functions placed on this page. This allows (e.g.) devices distributed over different pages to be separated.

Rename sub-identifiers

EPLAN allows you to divide structure identifiers into main identifiers and sub-identifiers, for instance "HLF1" (main identifier) and "HLF1.UA1" (sub-identifier). If a main identifier that contains sub-identifiers is to be renamed, a question is displayed as to whether all sub-identifiers should also be changed. If you click [Yes], the main identifier and all sub-identifiers are renamed; if [No], the renaming of sub-identifiers is canceled but the main identifier is still renamed.

Preconditions:

You have opened a project in which identifier blocks are used in the project structure, for instance "Higher-level function" and "Mounting location".
In your project there is at least one main identifier with a sub-identifier.

Project data > Structure identifier management
In the Identifiers - <Project name> dialog, select the identifier block you want to edit.
In the List tab, click in the Designation field of the main identifier you want to rename.
Enter the new designation.
Click [Apply].
Answer the question regarding the renaming of sub-identifiers.

Merge identifiers

If the designation of an existing structure identifier in the same identifier block is entered when renaming a structure identifier, the Status column of the structure identifier affected will automatically show a yellow warning triangle, and the detailed information will appear in the Message description field. If you ignore this, that is, you enter the structure identifier into the database with [Apply] or [OK], then the renamed structure identifier will take on all the properties of the existing identifier of the same name. If they exist, sublevel functions and mounting locations will be moved into the target identifier.

Precondition:

You have opened a project in which identifier blocks are used in the project structure, for instance "Higher-level function" and "Mounting location".

Project data > Structure identifier management
In the Identifiers - <Project name> dialog, select the identifier block you want to edit.
In the List tab, click in the Designation field of the structure identifier you want to rename.
Enter the designation of an existing structure identifier.

Status and Message description are automatically updated.
Click [Apply].
Answer the confirmation prompt to update the project.

Note:

If pages with the same name result from the merging of structure identifiers, then the process is canceled with an appropriate message.
