Copia provides support for CODESYS v3.5 SP 13-19, with advanced feature support for the following:


Copia supports CODESYS project files, with rendering for .project , .library and .export files.

Since .project and .library files are the standard working file, it is the recommended format for storage in Copia.

To get set up, simply store the file in a Copia repository. Once you perform the appropriate commit and push operations, you'll be able to see your project file and all of its data from both the Web App and Desktop App.

Configuring Export Files

You can alternatively choose to generate, .export files from CODESYS by clicking the Export button under the Project dropdown.

While you can export a subset of your project, we recommend that you export everything. Highlight all content and press OK to continue.

As with the process outlined for .project and .library files, place your .export file in a Copia repository and perform the required commit and push operations to store it on the Copia system.

Graphical Display and Differences


When the exported project file is selected in the Web App or Desktop App, Copia displays the project tree structure in a way that's familiar to users of CODESYS based software. This way, you can easily navigate to a project item or identify differences.

Rung Commenting for Code Review

Copia supports rung commenting for CODESYS for both Ladder and Structured Text.

Rung Commenting enhances the Code Review process once someone generates a Pull Request to merge a Branch. During the review process, users can add comments directly to the supported parts of the code.

You can watch an overview of rung commenting in the video below.

The product version in the video may be older than the current release, but the process is still applicable.
