WinCC OA is a Supervisory Control and Data Acquisition (SCADA) software platform deployed in more than 850 systems at CERN. It includes mission-critical installations such as the electrical grid, cryogenics, vacuum systems, detector control systems, and cooling and ventilation. Such systems continuously generate operational and experimental data whose long-term preservation and accessibility are essential for analysis and safe operation. For instance, variations in detector states across experiments are crucial for physics analysis, while abnormal events or alarms may signal conditions relevant to safe and reliable operation. However, the high volume of generated data presents significant technical challenges. The Next Generation Archiver (NGA) addresses these challenges by providing an efficient interface for storing and accessing data across heterogeneous database systems via pluggable backends. The introduction of a TimescaleDB backend further strengthens support for time-series data generated by WinCC OA. This presentation highlights recent developments in the NGA project, including the integration of TimescaleDB and an evaluation of its performance.
