3.20.1

Patches for WinCC OA are more than just bug fixes. 

Continuous feature integration makes it possible to implement enhancements in several different categories into our product. To keep your software up to date, make sure to download and install the newest patch. 

Highlights

Archiving

  • The NGA Importer for HDB now considers the value of the config entry [valarch] useHeaderSize = ["windows"|"linux"], which can be overridden by the new NGA Importer-specific parameter useHeaderSize = ["windows"|"linux"].

    This is necessary if you have switched operating systems while using the Value Archive archiving option (HDB) and now want to migrate your project to NGA.

  • Datapoint Element name substitution mapping: When importing HDB data to NGA, you can now load in a mapping file of DPE names. This allows for direct DPE replacement, if your data model needs to be adapted while conserving historical data.
  • PostgreSQL® DB: The documentation has been updated with extensive information on how to upgrade from a previous PostgreSQL® version to V16.

Drivers

  • MQTT: ECDSA type certificates can now be used.
  • BACnet: The WinCC OA BACnet driver is fully compliant to the Swiss KBOB guideline. This information has now also been clarified in the documentation.
  • SBus: The SBus driver now supports the function dpGetMaxAge().

OPC UA Client

  • In the OPC UA subscription panel, you can now optionally configure the Event Notifier Node ID for event and alarm subscriptions.
  • Additionally, event attributes for event subscriptions can also be selected.

Mobile UI

  • The selected language settings for the application are now stored on the device.

Project creation

  • The user interface for default user creation during WinCC OA project setup has been streamlined.

Video Add-on

  • The vimacc version 2.2.14.1 is included in the patch. This includes the SVG editor and layout sensitive bandwidth management features.
