Versiondog from the supplier Auvesy is a software used for the purpose of detecting and managing changes in automation devices. In order to safeguard programs and parameters, a copy of every program version of a controller and its settings is documented and saved centrally (who changed what when and why). Access to the system is granted by the user administration. Any changes made outside the change management system are detected automatically: versiondog compares the latest program copy with the program running in the controller. Any differences are reported by email notification. If any unauthorized changes have indeed been made, the latest approved program can be quickly restored from the archive, which contains all program revisions.
