A discipline component of the type WiringDiagram also serves as root component for the Pro Panel discipline. A resource is only assigned to this discipline component. All discipline components arranged below this have no resources but reference 3D graphics macros in the parts database.

Create the root component:

1. Select the ProPanel unit.
2. From the popup menu, select New > ECAD > WiringDiagram.
3. Click [Import...].
4. Select the file EPLAN\Data\Vorlagen\IEC_bas001.zw9.
5. Save the editor using [Ctrl] + [S].

In this process, the Parameter unit was created in addition (see ECAD Parameter Unit). This contains the parameters Location, Page_Number, Plant, Script, and Sub_Page_Number. The names of the parameters can be set under Model > Model Variables (see Model variables).

Create the following discipline components without resources:

1. Select the ProPanel unit.
2. From the popup menu, select New > ECAD > ECAD3D > Layout space.
3. Enter LayoutSpace in the Name field.
4. Save the editor using [Ctrl] + [S].

The following discipline components are also created without resources. To do so repeat Steps 1 to 4, with the following entries:

• New > ECAD > ECAD3D > Enclosure, Name Enclosure, Superclass Enclosure (enclosure that receives the additional components).
• New > ECAD > ECAD3D > MountingPanel, Name MountingPanel, Superclass MountingPanel (mounting panel in the enclosure).
• New > ECAD > ECAD3D > Diagrams, Name Diagrams, Superclass Diagrams (mounting surface, e.g. the front of the mounting panel).
• New > ECAD > ECAD3D > WireDuct, Name WireDuct, Superclass WireDuct (wire duct).
• New > ECAD > ECAD3D > MountingRail, Name MountingRail, Superclass MountingRail (mounting rail).
• New > ECAD > ECAD3D > Device, Name Device, Superclass Device (device, e.g. PLC, terminal clamps, etc.).

The icons and the level configuration of the discipline components have already been specified by the ECAD3D discipline. However, so that the components of the job definition can be properly arranged, the following parameters are required:

Name	Type	Meaning
Coordinate	Coordinate	For specifying coordinates when positioning objects
CoordinateMap	CoordinateMap	For specifying coordinates as a map when positioning objects Syntax: Map{Pair{'x',100},Pair{'y',100}}
DeviceTag	DeviceTag	Device tag
Dimension	Dimension	For specifying the length, the angle of orientation or the surface area. Syntax: =List{Length} or =List{Length,Angle} or =List{Length,Width}
DT_Code	String	Part of the device code (BMK)
DT_Counter	String	Part of the device code (BMK)
EPN	PartNumber	EPLAN Part Number is the part number of a device from the EPLAN parts database
Id	Id	Identification number that clearly identifies a mounting surface
Mate	Mate	For positioning objects in relation to the mates of a parent object. Syntax: =List{'Source handle','Destination mounting point',Distance}
MateMap	MateMap	For positioning objects in relation to a MateMarker. Syntax: =Map{Pair{'src','C'},Pair{'dest','C'},Pair{'dx',0},Pair{'dy',0},Pair{'dz',0},Pair{'angle',0}}
Plug	Plug	Components whose plug value corresponds to the socket value of a superordinate component can be installed there.
Position	String	Attachment sequence: the higher the value, the further back the object is attached.
Socket	Socket	Superordinate components provide a socket value that determines which subordinate components may be installed there.
Width	Double	Width of a constructed object. This value can be obtained from the parts data.

This parameter is created in accordance with the following schema:

1. Select the Parameter unit.
2. From the popup menu, select New > Parameter.
3. In the Name field, enter the text Coordinate.
4. In the Type field, enter the text Coordinate.
5. Save the editor.
6. Repeat steps 1 to 5 for each parameter that is listed in the above table.
