Practice docking control elements, too. To do this, click the title bar of the desired undocked control element e. You can recognize this by the border of the element being displayed as a thin line.

This will be a horizontal or vertical line, depending on whether you wish to position the control element at the top, bottom, left, or right.

You can recognize the orientation from the thinly drawn pre- view rectangle. When the program is exited, EPLAN saves the last settings of these elements docked, undocked, size, position and restores them the next time the program is started.

Moreover, another toolbar “Symbols” has been hidden and two more moved around inside the main window “Graphics”, “Connection symbols”. To avoid unnecessarily reducing the size of your EPLAN user interface, you have the option of hiding the toolbars you don’t need. Click the right mouse button on a free area in the menu bar or toolbar.

The popup menu shows all the available toolbars. Displayed toolbars are marked with a preceding checkmark. Select the Standard toolbar, for instance, and click the check box in front of the toolbar name. EPLAN closes the popup menu and hides the toolbar. Repeat the procedure and deactivate some more toolbars. Practice displaying unhiding toolbars too.

To do this, call up the popup menu again and click on the name of a hidden toolbar e. You can also use this dialog to customize and extend the predefined toolbars and create your own toolbars. Selecting workspaces Once you have changed the EPLAN user interface to suit your needs, you can save this arrangement as a “workspace. We provide you with a few predefined workspaces which you can use as templates for your own workspaces.

The Workspace dialog opens. From the Scheme drop-down list, select the entry Connections as an example of a workspace. Besides the Page naviga- tor, the main window now also contains the two windows Potentials and Connections.

In these special navigators, all the potentials and connec- tions of a project are shown. Restoring the original view 1. From the Scheme drop-down list, select the entry Default. EPLAN now shows the view displayed when it first started up.

Using this action, you can reset an EPLAN user interface that you may have changed back to the original state. You can find more detailed information about the user interface — for instance, how you can define your own workspaces — in the EPLAN online help. In EPLAN, schematics and attached documents such as lists and over- views are created as pages within projects. A project consists of a collec- tion of different types of documents.

Projects are stored and organized in a special database — “Project Management”. What is a project structure? In EPLAN, “Project structure” means the combination of all identifier structures used in the project for objects, pages, devices, and functions. All objects in a project pages, devices, and functions must be identified and placed in a hierarchical structure within the project.

In a hierarchical- ly arranged project structure, for instance, you can store and find pages and devices more easily. The identifiers for project structure are called “structure identifiers”. What is a project template? In order to create a new project, you always need a template.

When using the project template, you create a project in which some settings are already predefined. For instance, the structure of page identifiers and device tags are stored in a project template. Even as a beginner, you can use the Project wizard to quickly and easily get results. In the dialog of the wizard — the Create project Wizard dia- log — you can enter all the principal data for a new project step by step. The Create project Wizard dialog opens. In the Project name field on the first tab, enter the name for your first project.

Select a storage location for the project. To do this, click [ By default, your projects are managed in the Projects directory in a “company folder” created during installation in the illustration, the Company code folder. Select this “company folder” and click on [Make New Folder]. A new folder is created below the currently selected “company folder”, whose temporary name New Folder is highlighted with an edit frame. The Browse For Folder dialog is closed and you are returned to the Project wizard.

Select a Template for the project. To do this, click the [ If you don’t select a template here, you will not be able to perform any more steps in the Project wizard. The Open dialog opens. Click on [Open]. The Open dialog is closed, and the name for the project template is accepted for the Template field. The template and location now being used will then be the defaults next time the Project wizard is started.

Click [Finish]. The Importing project dialog opens. The Project wizard copies the template into the new project. This procedure may take some time. Projects form the first level in the tree icon:.

The levels with the project pages are typically below the level with the project name. The selected project template enables hierarchically arranged structures for all objects in the project.

It has a project structure already determined. Structure identifiers for the “higher-level function” and the “mounting location” are used to identify pages and devices.

This will, for example, be visible later when editing the page properties in the Full page name dialog see page The next chapter will describe how to create and edit pages. There, you will also read how to assign structure identifiers for the pages. Note: Once you are more familiar with EPLAN, you can use the different tabs of the Create project Wizard dialog to change the default settings from the project template regarding structure, numbering, and properties.

In this chapter, you will learn how to create pages and edit their page properties. A project gen- erally consists of pages of different types. The page types help structure a project. The page type is generally assigned when the page is created, but it can also be changed later.

The title page or cover sheet is usually the first page of a project. What is a schematic multi-line page? A schematic multi-line page is a page for which the schematic docu- mentation has multi-line symbols.

It has special editing capabilities for the creation and analysis of schematic diagrams. For instance, symbols inserted are automatically connected with one another. What is a graphical editor? A graphical editor is the part of the program you use to create and edit schematics and mechanical drawings. It is started when you open a page.

Besides the window in which the page is displayed, the menu bar also has numerous program functions such as the Insert menu avail- able for graphical editing.

The window is dockable and has its own standard Windows buttons. In a “maximized” view, the window of the editor fits into the main window in such a way that the title bar is integrated into the menu bar of the main window see also the illustration on page In the “minimized” view, the window has its own title bar. The Page type field is automatically prepopulated with Schematic multi-line I. In the Page description field, enter the text, Power supply.

Any page or structure level may be selected when you do this. Note: Based on the Beginner mode selected in the Select scope of menu dialog, you use fields that allow multilingual entries e. This function provides you with the whole word based on the letters you type in.

Only words in the dictionary will be suggested. In the tree view of the Page navigator, select the 1 Power supply page. Most property fields already have values. EPLAN accepts the properties of the selected page and automatically suggests the next free page for the Full page name. Click on [Clear fields]. The contents of some properties fields such as the Page de- scription field are deleted.

The automatically suggested Full page name and the prepopulated Page type are kept. Next to the Page type field, click the [ The Add page type dialog opens. In the Page description field, enter the text Cover sheet. For the Form name property, click in the Value field next to it, and then click the button that appears. No value needs to be entered for the Plot frame name property. The plot frame used for a page is already predefined in the project settings. The other displayed properties, Scale and Grid, are already prepopulated with correct entries.

The cover sheet is shown in the tree view of the Page navigator and opened in the Graphical editor. Then, in the Page type field, select the entry, Schematic multi-line I , and in the Page description field enter the text, Control ET1.

Now you have created the pages you need for editing the schematic. Closing a page Since you don’t immediately need the second schematic page, close it again. The page 3 Control ET1 is closed. In the tree view of the Page navigator, select the page 2 Cover sheet.

The cover sheet of the project is shown. This is the case, if in the View menu, you activated the menu item Workbook. In the Page navigator, you can recognize the opened page from the fact that the page name and description 2 Cover sheet are now in bold. Tip: To open a page selected in the Page navigator, you can also double- click on the page or press the [Enter] key.

Open the page 1 in the same way. This will automatically close the first page and display the empty schematic in the Graphical editor. For instance, select page 2 again, then from the popup menu of the Page navigator select the menu item Open in new window.

For every opened page, a tab is shown below the graphical editor window. You can quickly switch between pages by clicking these tabs. The pages created, however, don’t yet have struc- ture identifiers. In the following section, we describe how you can assign the identifier by editing the page properties. In the tree view of the Page navigator, select the cover sheet page 2 Cover sheet. The Page properties dialog opens. Change the value in the Full page name field. Here, you can enter the structure identifier and the name of the page e.

Enter the value ANL in the Higher-level function field. Enter the value DBT in the Mounting location field. In the Page name field, change the entry from 2 to 1. The Full page name dialog is closed. The structure identifiers are accepted for the field of the same name in the Page properties dia- log.

In the Page properties dialog, click [OK]. For the “Higher-level function” structure iden- tifier level with the identifier ANL, the icon will be used; and for the “Mounting location” level with the identifier DBT, the icon will be used.

Repeat this action for the schematic page page 1 and 3. In the Full page name dialog, as the structure identifier for the Higher-level func- tion, enter the designation ANL again. For the Mounting location, enter the designation SCP for the schematic pages. And for the second sche- matic page, in the Page name field, change the entry from 3 to 2.

Now all pages in the project have structure identifiers. You may first have to enlarge the Page navigator window a little before you can read all the page descriptions. Note: If you have made a change during page editing for instance, changed page properties, inserted graphical elements, etc.

There is no separate save necessary, and so there is no corresponding menu item in the program! You will also learn how to open and close a project, and you will learn a few basic com- mands for viewing and editing a project. Opening a Project 1. The Open project dialog opens. Here, the projects are shown which are located in your predefined project directory by default. Click [Open].

The page description is displayed in the Page navigator. Then repeat this for the plus sign in front of the structure level CA1, then for the next to the structure level EAA. The first section of the tree is opened. The pages are now dis- played in the “lowest” project level. First, page through the pages of this extensive project. The currently selected level in the tree view will be opened or closed. A minus sign before a level indicates that the level is already open.

For instance, if you want to show all the pages of a project in the tree at once, then select the closed level with the project name, and press the [X] key on the numeric block of your keyboard. For a larger project, this process can take some time. Paging Through the Project Pages Using the appropriate program functions, you can look at the pages of a project one after the other in the Graphical editor. Repeat this action a few times and look at the contents of the pages in the Graphical editor.

The pages are shown one after another in the Graphical editor. If the tree structure in the Page navigator was not yet completely opened, this will be done while paging through the pages. The page name and the description of the currently opened page are high- lighted in bold in the Page navigator.

Page back a few pages, too. However, if your cursor is located in the Page navigator, the keys will not page through the pages but will cause the cursor to jump to the bottom or top page shown in the tree view.

Turning on the grid display A glance at the two menu items View and Options will show you that in EPLAN there are numerous program functions which make it easier for you to draw schematics. You can work with a grid to make the positioning of elements easier. By default, in the Options menu, the menu item Snap to grid is activated. If this option is activated, the graphical elements and symbols are posi- tioned directly on the grid points of the grid during the drawing process.

The size of the grid used is stored as a page property. In the graphical editor, you can modify the grid size set by default to the respective page type. Using the to buttons in the View toolbar, you can switch be- tween five different grids, for which different grid sizes have been stored in the user settings.

Please keep the Snap to grid option activated during the subsequent schematic generation and use Grid C with the default grid size 4.

The grid size used is displayed in the status bar. The “ON” or “OFF” text in the status bar in front of the grid size indicates whether the snap to grid is activated or not see example regarding status bar on page The use of grid snap is independent of the grid display options. If this view bothers you later when creating the schematic, then turn the grid display off in the same way. For schematic editing, it is often a good idea to enlarge a certain screen segment in order to be able to see details better.

For instance, you can use the “window zoom” in order to show a certain window segment in an enlarged view. In addition to the mouse pointer, a magnifying glass will also be displayed. Left-click the mouse in the upper left corner of the schematic, and use the mouse to open an area which includes about a quarter of the schematic page. The area to be enlarged is outlined with a thick frame while it is being selected. Click the left mouse button again.

The selected area is displayed at maximum size. By de- fault, during scrolling the mouse wheel acts in the same way you are familiar with from other CAD programs. In the settings, you also have the option of changing the scrolling behavior so that it matches the behavior of text editing programs. In this case, when you scroll with the mouse wheel, the visible section of the page is moved upwards or down- wards.

Move the mouse pointer onto the element with the designation -Q1. The element is displayed in a different color. Below the symbol, a small text window Tooltip is displayed with information about the element.

Select the element by clicking on it. The color of the element changes again. The element -Q1 is completely deleted. You can, however, use the Undo command to reinsert the element. Note: When editing elements in the Graphical editor, besides the usual Win- dows operating methods first select elements, then call command , in most cases the reverse order of operation first call the command, then select elements is also supported.

Practice this once for the element -Q1 you just inserted. In addition to the mouse pointer, two other symbols are also dis- played.

The box with the red X is the symbol assigned to the delete function, and the box with the dashed line stands for the area to be selected. Left-click the mouse button on the upper left of the element, and use the mouse to drag a frame around -Q1.

The element -Q1 is removed. Closing a Project 1. If your cursor is in the Page navigator, then the project for which you have selected one or more pages is closed. Note: Please note that the menu item Close in the popup menu Page naviga- tor only closes the page currently located in the foreground.

Tip: In the Project menu, beneath the menu item Print, a list of the last projects opened is displayed. You can use this list to open a corres- ponding project without needing to use the menu item Open. You have just closed the demo project. EPLAN opens the demo project again. After it opens, practice closing it again. Now that you have looked at the complicated demo project in this chapter, in the next two main sections you will create a much “simpler” schematic. By default, symbols do not contain any logical data.

These are generally stored in the functions. Onlogicpages suchasthis schematicpage ,thecoordinatesareenteredingridincrementsandongraphicspages,theyareenteredin millimetersorinches.
