Description

Once a plant has been commissioned and validated, it may be necessary to make changes to the configuration due to the plant being adapted or extended. In this connection, youmust record all the changes to a plant from the start of production for the entire service life and, with software in particular, you must document reproducible versions.

This means that you must log the configuration, in a similar way to runtime operation, in the audit trail of the configuration: what is known as the "Change Log".

Using the WinCC flexible/ChangeControl option, it is also possible to carry out versioning and change tracking of WinCC flexible projects. You can log changes in the project and if necessary verify them should the need arise.

Design and functions

In general, you can use ChangeControl to secure interim status conditions in the case of complex innovations or extensions and to carry out a rollback.

OEMs and custom machinery builders can benefit from this capability that enables you to manage your projects with a clear overview, record delivered customer versions and later modifications, for example.

In the case of sub contracting work, tracking changes via ChangeControl may provide the basis for calculating the time and effort needed for modifications.
