1 Exchanging Symbol Libraries

The symbol libraries used in the project are entered into the project-specific settings

and can be exchanged for other libraries.

Preconditions:

• You have opened the project whose symbol library/libraries is/are to beexchanged.

• The symbols and variants used in the project must exist in both libraries. Thedecisive factor here is the position of the symbols in the library, i.e. the symbolnumber.

Options > Settings > Projects > "Project name" > Management > Symbollibraries

1. In the Settings: Symbol libraries dialog, in the field for the desired symbollibrary, click [...].

The Select symbol library dialog is opened. If the symbol library shouldnot be removed, then a message is displayed.

2. Select the desired symbol library.

2 Updating Symbols

A symbol library stored within a project can be modified outside the project at any

time. In this case, the old symbol library stored in the project can be replaced with themodified one. Only the graphic is changed by this, the function remains unchanged.

Precondition:

You have opened a project.

Utilities > Master data > Synchronize current project

1. In the Synchronization of master data - dialog, in theSystem master data field, select the symbol library / libraries that have

changed outside the project. Multiple selection is possible here.

4 Placing Symbols

You can place a given symbol once or several times on schematic pages in the

graphical editor, however you cannot select multiple different symbols for a singleplacement operation.

A preview of the autoconnection lines is shown in the graphical editor, which showswhere a connection from one symbol to another symbol is possible. As an extra aidfor placement, a line is also shown between the first placed symbol and the currentcursor position. This allows you to place symbols along a line.

Insertion points and connection points pointing in the same direction may not lie ontop of each other. If this occurs when inserting a symbol then an error message isdisplayed and the action is cancelled. (Exceptions to this are symbols containing

opposing connections laid on top of each other at the same point, e.g. T-connections.)

4.1 Connect symbols with other symbols in theschematic

Precondition:

You have opened a project and at least one symbol library and are viewing a

schematic in the graphical editor.

Insert > Symbol

1. Select the desired symbol in the Symbol selection dialog.

2. Click [OK].

The dialog is closed and the symbol hangs on the mouse cursor.

3. Move the cursor to the desired location in the graphical editor.

5 Preventing a New Placement of a Symbol

If you wish to edit a symbol, you can prevent the symbol from being used while you

are doing this. While the symbol is being edited, it can't then be newly inserted into aproject or edited by another user. Symbols already inserted into a project can still beused normally.Once you have finished editing the symbol you can then unlock it again. Only anunlocked symbol can be edited or inserted by another user.

Precondition:

You have opened a project and at least one symbol library.

Utilities > Master data > Symbol > Open

1. If you have not yet opened a symbol library, in the Open symbol library dialog, you first open the symbol library containing the symbol you wish to edit.

2. In the Symbol selection dialog select the symbol(s) you would like to edit.The preview on the right side of the dialog shows the symbols marked if youhave selected a node in the tree view, for instance, then all of the elementsunder it are shown graphically. (For space reasons, the display of the available

variants is omitted in this case.)

3. Change to the List tab.

4. Choose the Popup menu > Configure columns.

5. In the Column configuration dialog, select the Prevent new placement check box.

6 Exchanging Symbols or Components

A symbol only serves to provide a graphical representation of a particular function, it

does not contain any logic information. A component, however, is a symbol placed inthe schematic to which a function (and thus logic) has been assigned. For thisreason, the following distinction is made when swapping: If you swap a Symbol , thenthe logic (i.e. the function) remains unchanged. Only the graphical representationchanges. If, however, you swap a component then the function is also replaced. Inboth cases, the new symbol is selected using the symbol selection.

You can only swap symbols when the new symbol matches the function of thecomponent. EPLAN checks the number of connection points of the symbol to bereplaced. In the symbol selection, you are only offered symbols having the samenumber, or fewer, connection points as the symbol you wish to replace. Symbols

having more connection points than the symbol already in the schematic cannot beselected. For function definitions with a variable number of connection points, allsymbols are offered. When swapping a symbol, the function definition remainsunchanged.

Preconditions:

• You have opened a project and at least one symbol library and are viewing aschematic in the graphical editor.

• You have selected the symbol to be swapped.

Popup menu > Properties

1. In the Properties dialog, select the Symbol / function data tab.

2. Click [...] in the Number / name field.

The Symbol selection dialog is opened. The symbol is selected in the treeor list and is displayed in the preview window.

3. If you only wish to display symbols in the same function category, select theOnly display symbols of the same symbol function category check box.

7 Selecting Symbol Variants

A symbol can have up to eight variants with names from A to H and a contact image

variant. Alll variants for a symbol have common properties. They also behaveidentically, and have the same function. This way they always have the same numberof connection points and are only different in their graphical configuration of theconnection points.

You can select a different variant of a symbol by rotating the mouse pointer beforeplacing it.

Precondition:

You have opened a project and are viewing a schematic in the graphical editor.

Insert > Symbol


2. Click [OK].

The dialog is closed and the symbol hangs on the mouse pointer, whereby

the current variant used is the first variant (standard variant).


4. Press the [Ctrl] key and move the mouse around the symbol to switch

between all symbol variants.Or press the [Shift] key and move the mouse to switch between the mirroredvariants E to H.Or press the [Tab] key to switch the symbol through the rotated variants (A toD).

5. Place the desired symbol variant in the schematic (simple click).
