2. Create new tags (Controller Tags and Program Tags supported).

There are two ways to get tags, one is by importing .L5X or .CSV files (click Import

Tags…), another is by connecting PLC (click Get Tag Info…). After creating a project by

one of these ways, please use the same way in future for maintenance to prevent

compilation failure.

Recommended for PLC Offline: Import .L5X

Recommended for PLC Online: Get Tag Info

Comparison:

L5X CSV Get Tag Info

Can Decription be Imported? Yes Yes No

Need Adding Data Type? No Yes No

*Description is only supported for atomic tags. (Not supported for structure or array)


Get Tag Info:

1. After adding the driver in EasyBuilder Pro, check whether all communication parameters

are correct, and then click [Get Tag Info].

2. Select the tag information to be imported and then click [OK].

3. Click [OK] after tag information is imported successfully.

4. View imported information and click the close icon [X] to leave.


Import Tag (L5X):

1. Export .L5X file from RSLogix 5000 software. The path is: File -> Save as -> Logix

Designer XML File (*.L5X).

2. Add the driver in EasyBuilder Pro, click [Import Tags], select [Import Files] (*.L5X), and

then click [OK].

3. View imported information and click the close icon [X] to leave.

4. Click [OK] after tag information is imported successfully.


Import Tag (CSV):

The tags edited using RSLogix5000 can be exported as a CSV file, and then imported in

EasyBuilder Pro.

Note: For Tags that use Data Types such as User-Defined, Strings, Predefined, and

Module-Defined, please click [Data Type…] to add necessary data types before importing the

CSV file.

1. Export tag data to CSV file. ( [Tools] » [Export] » [Tags and Logic Comments] )

Note: The separator character in CSV file must be a comma “,”; otherwise the file is invalid.

The directory for changing system settings: [Control Panel] » [Date, Time, Language, and

Regional Options] » [Change the format of numbers, dates, and times] » [Customize] »

[List separator]. Please select “,” and export CSV file after setting.

2. In [System Parameters], click [Import Tags], select [Import Files] (*.CSV), .and then click

[OK].


3. Decide whether to keep the current data type (User-Defined, Strings, Predefined,

Module-Defined) or replace with default data type.

4. A Warning window appears when unsupported tags are used. Please check whether these

tags use data types, and add the necessary ones.

The following message pops up when the tags are successfully imported.


Data Types:

For Tags that use Data Types such as User-Defined, Strings, Predefined, and

Module-Defined, since the Structure cannot be exported as CSV file, please use Structure

Editor to add necessary data.

Structure Editor can be opened after adding “Rockwell EtherNet/IP

(CompactLogix/ControlLogix) – Free Tag Names” driver into the Deivce list and then click

[Data Type…]. Right-click on a Data Type (usually User-Defined), and then click [New data

type…] to edit the data type.


Add data types manually:

1. After adding Rockwell EtherNet/IP (CompactLogix/ControlLogix) – Free Tag Names driver

into the Device list, click [Data Type…] to open Structure Editor. Right-click on a Data Type

(usually User-Defined), and then click [New data type…] to edit the data type.

2. Enter the name of the data type. [Description] field can be left blank. To add a member,

click [Add].


3. Enter the name and data type and then click [OK].

4. After adding all members, click [OK]. The new data type will be added to the list on the left.

5. After changing the name or description of a data type, click [OK] to update.


Copy and paste the created Data Types:

1. Multiple memebers can be added at a time by clicking [Paste].

2. Enter a name, press Space key or Tab key, and then enter a data type. Copying from the

Sample is recommended in order to avoid error, please click [Sample].

3. The screenshot above shows a table of defined data types in RSLogix. Select these

names and data types using your mouse, copy and paste them to the editing window as

shown below.


4. Click [OK] and the added data can be found in Structure Editor.

Module-Defiend

Module-Defined is a default structure of a module.

Here is an example showing how to define the structure of a module.

In RSLogix5000’s I/O Configuration, some modules can be found.

T


he exported CSV file of the tags will not contain the structures. Please add necessary

structures manually.

1. In RSLogix5000 open [Controller Organizer] » [Data Types] » [Module-Defined] and

double-click on a data type. Members of the data type will be displayed, please copy the

Name and Data Type of the members.


2. In Structure Editor, right click [Module-Defined], click [New Data Type] and then enter the

Name.

3. Click [Paste] and use Ctrl+V to paste the Name and Data Type.


4. Select a member and then click [Edit]. Since the data of the modules allows bit-wise

operation, [Binary Access] should be selected, then click [OK] to return to Structure Editor.

5. Click OK to complete settings.

Other functions:

Revising member data

Double click the member to be revised, or click the member and then click [Edit].

Deleting member data

Select the data to be deleted and then click [Delete]. To delete all members of a

data type, press and hold the Delete button on the keyboard and then click the

[Delete] button in the dialog box.

Deleting a data type

Select a data type from the list on the left and then press the Delete key on the

keyboard.

Load from Template

To start over from default settings, click [Load from Default] button.

Save to Template

Save the edited data as a template for using in other files.

Note:

1. EBPro V6.03.02 or later supports 64 bits data type (cMT Series only), but please note

that the address limit range is 48 bits in maximum.

2. Please avoid using “.” in the Tag name because this may influence macro execution.

3. Shorter tag names are recommended for enhancing communication efficiency.

4. STRING data format must use Unicode for an ASCII object. When the data of STRING

is changed, HMI cannot calculate the length of STRING and write it into LEN.

5. Data format supported for Binary Access: INT, DINT, and SINT.
