Highlights and Release Notes

Performance

Fastest WinCC OA ever !

Event Manager up to 4 times faster

  • Core data throughput has been increased up to 4 times: This allows operation at only 1/3 of CPU load with the same data throughput. More ressources are made available on existing and new projects.

Event load reduced for NextGen Archiver

  • Choosing between the available options is now even easier than before: Projects with NGA Archiving now reach the same Event Manager performance level as RAIMA/HDB projects.

Ready for the year 2038 with SQLite DB

  • Tests with SQLite show the same Event Manager performance as RAIMA-based projects. That means this future-proof technology is now available with the same increased performance.

Further Notes

* These values have been generated through benchmark tests under standardized conditions. Overall system performance or results with your specific project might vary. If you require detailed information, feel free to contact us for our whitepaper on performance.

Licensing

New license options in version 3.19.

Video Streaming

  • To get out customers started on working with video with fewer costs attached, a new streaming-only option has been included in the Video Basic license. No initial camera licenses are needed, yet they can easily be added later if a stream recording function is required.

New BACnet license Options

  • BACnet object handling has been made easier with the goal of decreasing costs and effort in larger projects by introducing two additional license options: 30.000 and unlimited BACnet objects. For more information, see chapter WinCC OA License options (Features).
