Customizing Display Level, Colors and Fonts

Customizing a Display Level

You can adapt the selected display level to suit your purposes. S7-Graph provides the following options:

• Zoom in and zoom out

• Zoom factor for the current display

• Lasso functions for zooming

• Splitting the work area into two windows

• Buttons for handling windows

• Displaying and hiding selected areas

• Setting a default display for certain areas

Zoom In and Zoom Out

Select the menu commands View > Zoom In or Zoom Out to change the size of the display.

Specifying a Zoom Factor for the Current Display

You can adapt the size of the current display to suit its contents by selecting the menu command View > Zoom Factor.

If you select a zoom factor that would make text too small to be legible, the step and transition names are no longer displayed and only the numbers of steps and transitions are visible. You can, nevertheless, display step and transition names by positioning the mouse pointer on the step or transition.

If you want to avoid this, you can specify minimum zoom factors for the various views so that the display size never becomes illegible.

You can also revert to the previous zoom factor at any time.

Lasso Functions for Zooming

If you want to increase the size of a specific area, you can also use the lasso function. Drag a rectangle round the area you want to zoom using the mouse.

Select the menu command View > Selected Area. Now only the selected area is displayed in the S7-Graph work area.

Splitting the Work Area into Two Windows

With the menu command Window > Split, you can split the work area vertically into two sections and display the sequencer at two different display levels at the same time.

The left half of a split window is always displayed at the overview level. In the right half of the split window, you can set any other display level.

Steps selected in the left-hand pane can be edited in the right-hand pane.

Navigating in the Split Window

With the menu command Window > Next Pane, you can switch backwards and forwards between the two panes.

Buttons for Handling Windows

S7-Graph provides you with a button for toggling the message window on or off and a button for changing between the split window and the simple window. This allows you to set up the work area to suit your requirements.

Displaying and Hiding

Apart from displaying individual steps and transitions, S7-Graph provides further options in the work area. Select the required menu commands from the View menu:

• To display a comment field: View > Display with > Comments

• To display the address list: View > Display with > Address List

• To display addresses in symbolic representation: View > Display with >

Symbols

• To display with following/preceding references: View > Display with >

References

Defaults for the Display of Additional Elements

Additional elements can also be displayed as part of the default setting when a block is opened. You select the default with the menu command Options >

Application Settings in the "General" tab page. Select the displayed options to make the default setting:

• To display a block comment or a step comment: "Display Comments"

• To display the address list at the single step level: "Display Address List"

• To display addresses in symbolic representation: "Display Symbols"

Customizing Colors and Fonts

S7-Graph also allows you to customize the appearance of individual elements.

These include the settings for color, font, lines and Ladder Logic/FBD addresses.

Modifying the Settings

You can make all the required settings in the "Editor" tab page. You can display this tab page with the menu command Options > Application Settings. When you close the editor (when you quit the customize functions) any modifications you have made are saved.

Ladder Logic Addresses and Action Lines

You can decide the maximum number of characters permitted for a LAD/FBD address or an action line. For the view in the program, you can limit the address to one line.

Tip: If the LAD/FBD address or the action line is not displayed completely in a particular view, you can display the complete name as a tooltip by positioning the mouse pointer on the relevant address or action.

You can also specify whether the LAD/FBD address is right-aligned and the actions left-aligned.
