1 Determining the Format and Range for Numbering

Precondition:

You have opened a project.

Options > Settings > Projects > "Project name" > Devices > Number using PLC data

1. In the dialog Settings: Number using PLC data select a user-defined scheme from the drop-down list, or create a new scheme using (New).

2. In the Settings: Number using PLC data dialog, click (New) above the Format groups field.

3. In the Number using PLC data: Format dialog, select the group of devices from the Group drop-down list for which you want to determine the format. You can choose between terminals, pins, and devices.

4. In the Extent drop-down list, select the scope of numbering for the selected group.

Note: If you have selected the "Net" entry, then you can use the net extension to increase the area affected by the numbering scheme, as described in the section Defining Net Extensions.

6. In the Available format elements field select a format element and move it over to the right using into the list of selected format elements.

Different subsequent dialogs will appear, depending on the formatting element. Depending on the format element selected, this can be one of the following dialogs: Format: PLC data, Format: Identifier, Format: Page / column / row, or Format: Separator.


EPLAN Training 6

7. Define the formatting in the subsequent dialog.

In the Preview field, a preview of the numbering format is displayed. The individual formatting elements are displayed in the connection designations in the same sequence as they currently exist in the list.

8. If desired, you can change the sequence of the formatting elements using the arrow buttons.

9. Click [OK].

The values entered will be saved in the selected scheme.

2 Defining Net Extensions Typically a net ends at terminals, plugs, or connection points of functions. Use the net extension function to expand the net with terminals and plugs. To do this, specify in the net extension dialog which functions should not be treated as a boundary for the net. This setting affects the designation if the range is selected as "Net".

Precondition:

You have opened a project.

Options > Settings > Projects > "Project name" > Devices > Number using PLC data

1. In the dialog Settings: Number using PLC data select a user-defined scheme from the drop-down list, or create a new scheme using (New).

2. Click [Net extension].

3. In the Net extension dialog use the arrow button to move the desired functions from the Selection list into the Net extended with following objects list.

The net will then no longer end at the selected functions, but rather it will be extended by them.


EPLAN Training 9

The net extension applies to all format groups contained in the "Net" scope.

4. Click [OK].

The setting will be saved in the selected scheme.

3 Continuing the Numbering behind a Function If the numbering should be continued after a function at which (based on the scope configuration) the numbering would stop, then specify this at the function involved.

Precondition:

You have selected a function in the graphical editor.

Edit > Properties

1. In the Properties dialog in the tab, activate the "Continue numbering with PLC data beyond this function" property (Properties group box).

2. Click [OK].

When numbering with PLC data, those devices will also be numbered which are connected to this function.



EPLAN Training 11

4 Excluding the PLC Connection Points from Numbering

When numbering with PLC data, all devices connected to PLC connection points are numbered by default if they are included in the scope. However, you can exclude certain PLC connection points from the numbering.

Precondition:

You have selected a PLC connection point in the graphical editor.

Edit > Properties

1. In the Properties dialog, in the PLC connection point tab, activate the Prevent numbering with PLC data property.

2. Click [OK].

When numbering with PLC data, devices connected to this function will not be numbered.

5 Numbering the Devices Connected to PLC When numbering with PLC data, devices included in the scope of numbering are numbered. General devices take the PLC data into their DT corresponding to the settings; terminals and pins incorporate it into their designations.

Note: When numbering with PLC data, only digital or analog inputs and outputs are taken into account. Devices connected to general PLC connection points are not numbered.

Preconditions: In the graphical editor, PLC connection points are selected, or one or more

pages are selected in the page navigator on which PLC connection points are located.

You have specified the scope and format of numbering.

Project data > Devices > Number using PLC data


EPLAN Training 14

1. Select a scheme defining the settings for the numbering from the drop-down list in the Setting field.

In the Format groups used field, the groups of devices which will be numbered are shown.

2. In the Overwrite group box, specify which DT / designations should be overwritten during the numbering.

3. Select the Mark as "Numbered using PLC data" check box so that functions changed by numbering will be flagged.

During numbering, the "Numbered using PLC data" property will be set for these functions.

4. Select the Preview of result check box to see a preview of the numbering results before the new device tags / designations are adopted.


EPLAN Training 15

5. If necessary, change the device tags or designations in the Number using PLC data: Preview of result dialog, and click [OK].

6. Click [OK].

The devices included in the scope of numbering will be numbered according to the formatting settings and accept data from the PLC connection point into the DT or designation.
