The SIMATIC PCS 7 add-on, versiondog, can be used by the operator of a SIMATIC PCS 7 plant for the following tasks:

• Performing all data backups and managing software versions throughout the entire lifecycle of the SIMATIC PCS 7 plant
• Cyclical check of the validated version through automatic data backup and comparison of the saved version to the most recently released, stored version
• Mapping of the entire configuration of a SIMATIC PCS 7 system including the change history from commissioning to the current time of the plant operation
• Comparison of the SFCs and CFCs of two versions of a SIMATIC PCS 7 project using "SmartCompare" (all differences are highlighted in color and can be selected)
• Complete documentation of changes in a SIMATIC PCS 7 project, for example, audits, validations and certifications
• Version control of the software for immediate recovery in case of problems (disaster recovery)
• Restoration of optimized software versions
