Summary 

The following summary shows a brief list of what has to be done to create or modify a symbol.

If you wish to modify an existing symbol

• Switch on the snap grid with F5
• Activate the library in which the desired symbol is saved.
• Bring the symbol to the screen using Delete+Load.
• Delete previous parts of the symbol and draw new ones.
• If necessary, delete pins and re-set them with type, shape and direction.
• Enter pin numbers and/or pin names.
• If necessary, change symbol name and possibly the reference name

Activate another library if the symbol is not to be saved in the same library.

In the library, select Save component, specify the suspension point and the symbol will be saved. In order to check, use Delete+Load or even Paste (for direct comparison) to bring the symbol back to the screen.

If you wish to create a new symbol

• Adjust the grid range under Options (optimum, 2.50 mm or 0.1 inch).
• Enter number/cabinet (select no more than 1).
• Select symbol type.
• Create shape of symbol. Switch between snap grid and ortho using Keys F5 and F6 as needed. Bear in mind that the pins must be arranged inside a grid area.
• Set the pins with the shape (point), type and direction. The snap grid is automatically switched on. Specify the pin number and possibly switch off Auto for better positioning. You can also specify the pin name and make it invisible (! as the first character).
• Enter the symbol name (usually invisible).
• Enter the reference name. The position and correct text alignment is important (may be placed left of the symbol).
• Activate the library (if the correct one is not already selected) or create a new one.
• Select Save component and after specifying the suspension point, the component is saved.
• Load again with Library – Delete+Load in order to check.

Note

A detailed example of symbol creation is described in the practice example of the Installation and Practice Manual and  you should at any rate read the entire example.

Special features of the terminal symbol

When creating a terminal, some special features must be taken into consideration because of the additional information for the automatic functions (Terminal destination direction and Numbering location).

• In the symbol editor, first enter 1 for Number / Cabinet.
• Select symbol type Terminal.
• Allocate Draw body, Symbol name and Reference name.
• Set pins: Each terminal must have at least 2 connections (or better: 2 + bridge pins). Set passive pins in point form on top of one another. A terminal can also have more pins (multi-storey terminals) but must be one symbol. Only one number is allocated to each terminal when numbering, regardless of the number of pins.
• The pin orientation is set manually (e.g. right) not automatically. In so doing, you also immediately specify the orientation of the pin numbers created during automatic terminal numbering.

Note

The pin orientation during automatic numbering is altered according to the configuration.

Allocate all pin numbers – the automatic positioning should be switched off.
Position the pin numbers to how they should appear later during auto-numbering.
Next, delete all pin numbers again (not with the space bar but with the backspace key). You have now allocated the positions for the automatic numbering.

The pin name is used to label the internal side of the terminal (terminal destination). Likewise, allocate all pin numbers because of the position determination. Delete the pin names again at all pins of the outer side. What you enter as the pin name is not important, a full stop (.) is usually used. With multi-storey terminals, it is useful to use + or - to distinguish between different pin names.

Draw another pin using the point shape and of the type bridge. e.g. in the centre of the terminal. The pin must only be used for the bridge connections of terminals. The bridge pins can be connected in the drawing by means of a continuous line – coordinate points are not necessary.

Save the component in the library.
