1 Drawing Schematics in Single-line Representation

For the single-line display of schematics, you can use pages with a special page type. The placed symbols are connected together via autoconnecting. Using a connection definition point, you can display the number of conductors in the cable.

Precondition:

You have opened a project.

Page > New

1.1 Create a page for single-line display 1. In the New page dialog, select Schematic single-line from the drop-down list

in the Page type field.

EPLAN creates a page of type Schematic single-line.

2 Showing Bus Topologies In EPLAN, bus topologies can be shown using PLC boxes and bus ports, which you insert on schematic pages in single-line display. Depending on the bus topology, PLC boxes can be used for different components. From a physical point of view, PLC cards can be stacked and combined into a so-called "bus node". The individual bus nodes can then be located in different places and are connected together using corresponding bus cables. To create a bus topology with PLC cards, proceed as follows:

Precondition:

You have opened a page of type Schematic single-line in the graphical editor.

2. Draw the PLC box representing a PLC card as a rectangle.

3. In the properties dialog, enter the device data for the PLC box.

4. Click [OK].

5. Repeat the previous steps for all the other PLC cards.

2.2 Insert bus ports 1. Select the menu item Insert > Box / connection point / mounting panel >

Bus port.

Single-line Display

EPLAN Training 13

2. Place the bus port within the PLC cards.

3. In the properties dialog that appears, enter the device data for the bus port; for the function definition select "Bus input" or "Bus output".

Single-line Display

EPLAN Training 14

4. Click [OK].

5. Connect the corresponding bus nodes together for each bus system by generating autoconnect lines between the bus ports on the PLC cards.

2.3 Insert bus cables Bus cables for bus systems are generally implemented using connection definition points.

3 Single-Line Display Compliant with the GOST Standard

In the GOST standard, it is permitted to combine multiple connections together into one line. In the vicinity of the connection points, the individual connections must be shown in individual form (multi-line) again. Combined connections must be labeled on the points at which they leave the bundle and where they enter the bundle.

Precondition:

You have opened a page in the graphical editor.

1. Place the desired symbols on the page in the graphical editor.

Single-line Display

EPLAN Training 19

2. Place several bundle connection point symbols (T-node, angle, etc.) at the desired component to combine them to a bundle connection point.

Single-line Display

EPLAN Training 20

3. Generate another bundle connection point for the component to be connected.

The bundle connection points are connected together via autoconnecting.

4 Creating a Bundle Connection Point Symbol Bundle connection point symbols are special symbols which make it possible to transition from the multi-line to the single-line display.

A bundle connection point symbol is combined from multiple individual symbols. You can put together your own bundle connection point symbol. The individual parts are connected together with a special colored autoconnection line. The following symbols are available in all four angle variants:

T-node

Double junction for the combined connection point

Two angles for the ends (right and left)

T-node for the connection points between the ends.

The thin ends of the bundle connection point symbols are the connection points to the components, while the wide ends are the connection points to the autoconnection line.

Precondition:

7. In the Edit bundle connection point data dialog, enter the desired designation for the connection point into the Bundle connection point designation field and click [OK].

Single-line Display

EPLAN Training 31

The Bundle connection point designation is accepted and displayed in the graphical editor.

Note: Bundle connections (autoconnecting and symbols) are graphically not influenced by entries for the connection graphics on potentials or on connections.

5 Comparing Functions / Components between Single-Line and Multi-Line Displays

If you make a change to a multi-line object or a single-line object belonging to one, you can synchronize the objects with one another. You can be sure in this way that the change has been transferred to the matching counterpart object.

Precondition:

You have changed an object in the overview or the graphical editor.

1. Select the desired object.

2. Select the menu item Utilities > Synchronization and, for a multi-line object select Multi-line --> single-line and overview, for a single-line object select Single-line --> multi-line and overview and for an object in the overview, select Overview--> multi-line and single-line.

6 Numbering Cables by the GOST Standard According to the GOST standard, the numbers of the cables are shown in circles. This circle interrupts the connection (autoconnecting) in the vicinity of the connection point.

Precondition:


Insert > Symbol

1. From the Symbol selection, select the symbol for the two-sided cable definition.

2. Place the symbol on the autoconnecting line between the desired objects.

3. In the properties dialog, enter the connection data for the cable.
