1 Inserting PLC Cards and Connections

You can insert PLC cards and connection points on schematic pages and also on

pages of type "Overview". Synchronization occurs between the overview pages andthe schematic pages. All of the PLC connection point data can be entered in both theoverview and in the schematic.

1.1 PLC card overview

A PLC card is represented in the schematic by one or more PLC boxes. To insert aPLC box, proceed as follows:

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

PLC box.

3 Editing the Properties of PLC Cards orConnection Points

You can edit the data for a PLC at every position in the project where this dataoccurs: On the schematic page, the overview page, in the bus configuration, and inthe navigators. Changing the hardware data (e.g., the connection point designation)in the schematic does not change this data on the overview page.

• In the graphical editor, you edit the properties of placed PLC boxes andconnection points.

• In the navigator dialogs PLC -  or Devices -  dialog, you edit the properties of all PLC boxes and connection points in the

project (placed or unplaced).

3.1 Edit PLC data in the graphical editor

4 Addressing the PLC Connection Points

It is possible to re-address specific or entire areas of PLC connection points within a

PLC controller (several PLC connection points, one or more PLC cards). The settingsand formats from the PLC settings are taken into account.

Precondition:

You have selected several PLC connection points in the schematic, or in the PLC - navigator dialog; or project pages (or a project) containing PLCconnection points are selected in the Pages -  navigator dialog.

Project data > PLC > Address

1. In the Readdress PLC connection points dialog, select a scheme definingthe settings for the addressing from the drop-down list. Or click [...] to create anew scheme in the dialog which appears, to save changes to a scheme, copya scheme, or delete one. Schemes can also be imported or exported.

2. Select the Digital connection points and / or the Analog connection points check boxes to define which connection points are to be addressed.

3. In the Digital start address and Analog start address fields, enter thestarting address for the first digital and analog PLC connection points. Thecurrently defined addressing format is displayed as an aid.

4. Use the Sorting drop-down list to define the order in which the PLCconnections are to be sorted. The connection points are fundamentally sortedby the DT of the card; in addition, sorting can occur by the graphical order inthe schematic, in the order of channel designations or in the order of theconnection point designations.

5. Select the Preview of result check box to see a preview of the results beforethe new addresses are adopted.

5 Using the Existing PLC Connection Points

If your project contains unplaced PLC connection points, you can re-use these and

assign their properties to the placed connection points.

At a single PLC connection point, you can use the Properties  dialog to re-useanother connection point. In the Use existing PLC connection points blockwise dialog, you can re-use several connection points at the same time (also for differentplacements).

5.1 Re-use single PLC connection points

Precondition:

You have opened the Properties  dialog for a single PLC connection point.

1. Select the  tab and click [...] next to the Displayed DT field.

In the DT - selection dialog, all PLC connections used in the project areshown.

2. Click [OK].

The selected unplaced PLC connection points are displayed in the From table.

3. Use the arrow keys to move the unplaced PLC connection points in the right-hand table and assign them to the existing placed PLC connection points inthe left-hand table To.

When moving, the entries may only be moved to another free position; nochange occurs to the unselected, occupied positions.

If the selected quantities are different, then this is balanced by appendedempty lines.

4. In the Use existing PLC connection points blockwise dialog, above the

table From, click [...] if you wish to re-open the Select unplaced PLCconnection points to place them blockwise dialog. Select the desired PLCconnection points and click [OK].

8/9/2019 0603 PLC

26/36

  PLC

EPLAN Training 26

5. Click [OK].

The PLC connection points are re-used, i.e., their properties are adoptedby the assigned, placed PLC connection points.

Notes:

• If, for a function in the schematic, you have also selected the associated functionin the overview page, then the same connection point is re-used for bothfunctions. Both placements then belong together after this. (If only oneplacement was selected, then the relationship is lost!) Only one common entryis displayed for both placements in the left-hand table. If the addresses of thetwo placements are different, then the character string is displayed in

the table. The character string is also displayed for differentrepresentation types.

• If multiple PLC connection points exist in the project (with the same DT andconnection point designation), then both are listed. If the PLC connection pointoccurs several times in the schematic and the associated PLC connectionpoint on the overview page only once, then only the graphically first PLCconnection point in the schematic is assigned to the relevant connection pointin the overview page.

This functionality is only available for certain module packages. Info

7 Importing or Synchronizing Assignment Lists

Assignment lists can be imported in the Siemens formats *.SDF and *.SEQ, or as

ASCII data*.ASC

. In addition to this, files with any file name extension can beimported if they conform to the structure rules for assignment lists.

Project data > PLC > Addresses / assignment lists > [Extras] > Importassignment list

1. Select an assignment list from the Select file dialog.

2. Click on [Open].

3. In the Import / synchronize assignment list dialog, define what PLCcontroller data is to be read using the PLC CPU field.

All CPUs existing in the project are offered in the drop-down list.

Note:

o If you wish to perform a pure Import  (i.e., without overwriting any PLCdata in the project) enter a CPU here that is not in the project.

o If you select an existing CPU then the data is Synchronized .

EPLAN Training 32

o If you do not enter a CPU, the entries from the assignment list areassigned to the unnamed CPU. If an unnamed CPU already exists in

the project, then existing entries are overwritten according to thereference value.

4.

5. In the PLC-specific settings field, select a scheme from the drop-down listdefining the settings for the addressing format.

6. In the Language selection field, select a suitable language for theassignment list.

All languages defined in the translation settings for the project aredisplayed in the drop-down list.

7. In the Reference value field, you define the criteria used by the system torecognize existing entries. The CPU is always compared; within a CPU, eitherthe address or the symbolic address serve as the base value. Identical entriesare overwritten and the others are added to the list.

Note:

In the case of a pure import (i.e., a new CPU), the value in this field is notrelevant, since no addresses exist for this CPU yet.

8.9. Select the Import / synchronize all identifiers check box if you want to

import all  addresses existing in the assignment list. The designations are notaccounted for, i.e., addresses that are not defined in EPLAN are also imported(e.g., timer, tag etc.). Otherwise, only the identifiers specified in the PLC-specific settings dialog, in the Addresses tab are defined.
