Product Description

Apache™ Subversion® (SVN) is a tool for versioning and revision control of current and historical versions of files such as source code, web pages, and documentation. Apache™ Subversion® is a registered trademark of the Apache Software Foundation. See the package information in the package manager for more information.

Revision control, also known as version control or source control, is the management of changes to documents, programs, and other information stored as computer files. It is most commonly used in software development, where a team of people may change the same files. The main tasks of a version control system are:

  • Log of changes: It can be reproduced at any time what changes have been made, when and by who these changes have been made.

  • Restore of old revisions of single files. Changes of files by mistake can be undone at any time.

  • Archiving of specific revision of a project. It is always possible to go back to older versions.

  • Coordination of shared access of developers.

  • Simultaneous development of multiple branches of a project.

The Subversion functions are directly available in CODESYS both in the 32-bit and in the 64-bit variant. The application is seamlessly integrated in the CODESYS development environment.

CODESYS SVN can be installed and started in the CODESYS Development System without a license. To connect to an SVN repository, a license key is required in the demo as well as in the full version.
