3.20.2

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. 

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.

The patch is available for download on the SIMATIC WinCC Open Architecture World: https://www.winccoa.com/downloads/category/wincc-oa-320.html
