Patch Release Notes

Documentation

The WinCC OA Online Documentation has received a complete makeover that greatly improves its usability. It has been outfitted with a modern, responsive design which makes the use, especially on mobile devices, much easier. Furthermore, the documentation’s internal structure has been adapted to create quick and logical pathways leading the user to the information they’re looking for faster and more intuitively.

Please note that currently the new Online Documentation does not work with the Samsung Internet 26 Browser (27 Beta is already available for download!).

WinCC OA JavaScript Manager for Node.js

The JavaScript/TypeScript API of the WinCC OA JavaScript Manager for Node.js has been enhanced.

• New supported methods:
  • Plantmodel / CNS methods
  • dpGetPeriod, dpGetPeriodSplit and alertGetPeriod methods
  • dpQuerySplit and dpCancelSplitRequest methods
  • sysConnect method
  • Various other methods
• It is now possible to forward callbacks from Control code to JavaScript/TypeScript when the code is running in the JavaScript manager.

Further details can be found within the API documentation.

Video

Several improvements have been made to the Video OA Object Explorer:

• SVG Overlay and Privacy Zone configuration can now be copied from one stream to another.

• An option for live as well as archived streams to be viewed in vimaccOA Workstation for each camera has been added.

• The handling of user defined parameters/keys for camera configuration has been improved.

Security

WinCC OA OS authentication on Windows now works without any NTLM function calls, since NTLM is deprecated by Microsoft. The former WinCC OA behavior can be restored by using the config entry [general] useWindowsNTLM = 1 (default value 0).

WebView EWO

The WebView EWO now allows access to resources at a webpage’s request. Possible features as available in QT libraries can be viewed here: Qt - WebEngine Feature Permissions

An issue affecting the ULC UX reconnect in case of connection errors as well as a server shutdown has been fixed. This new behavior can be set by using the config entry [ulcUX] autoReconnectOnShutdown = 1.

Calendar

The calender object now provides an Today button that allows to select the current date within the calender. For more information, see chapter Calendar - Today.

Drivers

• IEC61850: A new config entry has been created to fix an issue that may infrequently cause the driver to run into timeout.
• SNMP: The max-repetitions number of an individual SNMP GetBulk request can now be independently configured.

Node.js

• Several CNS methods have been added to the WinCC OA JavaScript Manager for Node.js.

CTRL

• A new CTRL class "ReduMonitor" has been introduced that will make sure code is executed without data loss in the redundant CTRL manager on a Redu system’s active server. This functionality is helpful if the CTRL script is communicating to a single external database or service.

Screen Recorder

• All Modules and Child Panels will now show a red frame to indicate the inputRecorder is currently recording. This can be especially helpful when it comes to the login panel, to make sure not to inadvertently record the password entry.

Security

• Security for our HTTP server has been further increased with the full Server Hardening option, which completely disables code transfer capability. This feature is especially useful for customers who only use ULC-UX or Remote UI, as it allows for the use of the SSA feature without fear of potentially exposing unwanted data.

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.
