WinCC/ChangeControl
Tracing of project changes
Monitoring project changes is possible with WinCC/Audit and with the option
package WinCC/ChangeControl as well. In this connection, WinCC differentiates
between configuration changes that affect the WinCC database, e.g. changes in
Tag Management or creating a user group and configuration changes that are
limited to changes to files, what is known as document control. Document
control involves process pictures, scripts and log layouts and customer-specific documents.
This means that WinCC/Change Control can monitor all these documents or files for changes, create intermediate versions or retrieve them using a rollback
function. The entire monitoring process can be activated very easily and
conveniently. This means that in the case of plant standstills, for example,
plant engineers and operators can quickly and easily comprehend the changes that
have been made to the plant. This supports trouble-shooting and reduces plant
downtimes.
Benefits
- Project versioning and document control
- Compliant with the requirements of the Food and Drug Administration
(FDA)
- Reduced engineering effort to comply with 21 CFR Part 11 & EU 178/200

Using a project versioning tool
- WinCC projects can be archived, restored and deleted,
- WinCC data including the project database, project files (e.g. screens,
reports, scripts) and user documents can be archived
- Activities of the project versioning tool can be recorded
Fig. Administrating a WinCC project by employing the project versioning tool
In this way all changes made to a plant beginning from the production start
and continuing throughout the entire life cycle can be recorded and - using
defined versions - be documented.
