Using the example of the black box we illustrate how to create components.

Hints Hints Hints

Hints: It is recommended to set a 5 mm grid for the drawing of circuit diagrams. You can draw new components using a grid of 5mm, 2,5 mm or less. Make sure that the created symbol fits into a 5 mm grid, i.e. the connections have to end at appropriate grid points. You can set the grid via Toolbars.

There is a function under Toolbars for showing the grid.

The line width should be controlled. The line width for drawing connections must be identical with the line width for drawing wires. Most included symbols are drawn using a 0,25mm line width.

Exercise 7 Exercise 7 Exercise 7

Exercise 7----1:1:1:1: Draw the graphics for the component. You must use only the ordinary drawing functions, such as Line, Rectangle, Circle etc., but not wires!

• Create a new page in your workspace using the given functions.

• Construct the graphics.

1.M Draw

2.M Rectangle

• Draw a rectangle with width 20 mm and height 5 mm. This is possible on the default grid of 5mm. The width and height of the rectangle are shown beneath the drawing area as you draw.

4.+ Left-click the right bottom corner point for the rectangle.

5. Right-click to quit drawing the rectangle.

6.M Draw

7.M Line

• Draw two connection lines above and below the rectangle. These connection lines should be 5 mm long. The length of the lines is shown beneath the drawing area as you draw.

8.+ Left-click the starting point of the line.

9.+ Left-click the second line point.

10. Right-click to finish, do not draw a polygon.

Afterwards, you can draw the next line.

11.+ Select the starting point.

12.+ Select the second point.

etc.

• Right-click to finish drawing, do not draw a polygon.

• Right-click to finish drawing, you must not draw more lines.

Exercise 7 Exercise 7 Exercise 7

Exercise 7----2222:::: Define the symbol.

The graphics must be defined as a symbol.

1.M Edit

2.M Select Single Element

3.+ Left-click the first point of the frame.

The frame (rectangle) must include all of the graphics.

4.+ Click the second point of the frame.

5. Right-click.

6.M Choose the Block Block Block function from the context menu.Block

7.> Block/Component definition

• Choose the desired property for the symbol.

8.> OK

The chosen Block/Component definition determines the kind of database list or graphical list where the symbol will be listed. A contact cross appears beneath CoilCoilCoil symbols, but not beneath Coil Component

Component Component

Component symbols.

9.# A

• Assign the letter code to the component name.

10.> OK

The graphics has been now completed with texts for the name, description, type and connections. The graphics and the texts have been grouped as a symbol ComponentComponentComponentComponent.

The letter code AAAA for the component is replaced with the right identification of the component, for example 2222A8A8A8A8.

Hints for the automatically located connections Hints for the automatically located connections Hints for the automatically located connections

Hints for the automatically located connections: Connection points are located automatically at all of the lines, which stick out of the symbol horizontally or vertically (they are surrounded by an imaginary rectangle).

At the diode, there are too many connections. In the following tasks, you will learn how to delete these connections.

– If a symbol already has connections, no other connections will be automatically placed

(otherwise the diode connections could never be removed). In this case you must, for example, copy the existing connections.

– The order of placing the connection points corresponds to the order of creating the lines (drawing or copying).

– The default settings for the automatically inserted texts are made in the symbol library SYSTEMSYSTEMSYSTEM.SYSTEM

Exercise 7xercise 7xercise 7xercise 7----3:3:3:3: Save the symbol in the symbol library.

If the new symbol is used not only in the current workspace, but it must be available for future projects, you must save it in the symbol library. If the new symbol is used only in the current workspace or it will be copied from the current page into another place if needed, it is not necessary to save it in the symbol library.

1. Activate the SymbolsSymbolsSymbols area.Symbols

If the Workspace area Workspace area Workspace area Workspace area is visible, click the SymbolsSymbolsSymbols tab Symbols to activate the Symbols area.

2. MySymbols

• Double click the database Favorites Favorites Favorites Favorites to open it....

You can save only in this database or in a new database that you have created.

3. Right-click with the mouse.

4.M New Folder 5.# Relay coils

• Type the name of the new symbol database.

6.M Edit

7.M Select Component 8.+ Identify the new symbol.

9.+ Drag the symbol into the just now created folder in the symbol database. Hold down the left mouse button while you are dragging the symbol.

Important!!!!!

Drag always the upper left connection of a symbol into the d Drag always the upper left connection of a symbol into the d Drag always the upper left connection of a symbol into the d

Drag always the upper left connection of a symbol into the database. The symbol point that you hold atabase. The symbol point that you hold atabase. The symbol point that you hold atabase. The symbol point that you hold while dragging into the database will be later the point that you place!

while dragging into the database will be later the point that you place!

10.> Name 11.# Relay coil

• Type the symbol name and a symbol description.

The symbol has been saved in the symbol database.

Now, you can place the symbol again. But do not do it, press the right mouse button.
