View the History of Elements
View the history of elements such as projects, libraries, controllers, programs, functions, and function blocks. The history of an element is available from the time of creation.
When viewing the history of an element, a list displays all available versions of the element with their assigned version numbers. Each version entry includes the date, the user, the action, and a description from the check-in. The project version number pertains to the revision number in the repository currently used. Switching the project to another repository might cause the revision number to change.
TIP:
When a controller has been renamed, execute the View
History command on the most recent version of the controller.
When viewing the history of elements, perform these tasks:
Task | Procedure |
|---|---|
Retrieve a specific version of an element | Before getting a previous version for a controller with binding changes, check out all controllers affected by these changes. When retrieving a specific version from the version control history, the local element and its sub-elements revert to those from the version control. The Get Version command only gets application binaries on update or
download actions for the selected controller version. Updating the controller
requires these application binaries.
