WinCC flexible/ChangeControl
Versioning and tracking changes
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.

Benefits:
Consistent Backup of configuration data
Management in a database
Version management for changes to the project data (with
a rollback function)
Tracking of changes to configuration
Contiguous verification of the change history for the
entire life cycle
Validation support
Makes validation easier
Support in retaining the validated status of the plant
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.
