Chapter 1 Import and export files
36 Rockwell Automation Publication 1756-RM084S-EN-P - March 2015
The Controller component is the overall structure of the import/export file. It
contains the configuration information and logic of the controller project.
Preceding the Controller component is an optional XML declaration and a
required root element tag (RSLogix5000Content) that includes Logix Designer
application version information.
All components in an .L5X import/export file follow this structure.
<component_type [attribute_list]>
[body]
</component_type>
Item Description
<component_type> The component begin tag.
attribute_list List of attributes for the component in the form:
attribute_name="attribute_value"
Separate attributes with a space.
body The content of the component. The content could include any
subcomponents, for example, routines contained within a program, or a
description of the component. The content could also include information
about the component, for example, the data for a tag component.
The body of the component is optional.
</component_type> The component end tag.
A component with no content in the body may combine its begin and end
tag as one tag:
(<component_type attribute_list />
The .L5X file is an ASCII file that is structured by using Extensible Markup
Language (XML). In addition to being able to open and modify the .L5X file in a
text editor, such as Notepad, you can also view the contents of the file in Internet
Explorer® and other tools that work with .XML files.
