Performance

WinCC OA Is Still Getting Faster!

DP Functions/Hotlinks

• Improved performance for message handling in the central Event Manager for messages generated by the calculation of datapoint functions. ​
• This leads to a massive increase in performance when a lot of datapoint functions are triggered at the same time (peak situations).​
• Please keep in mind that a high number of data point functions may have an immediate impact on overall system performance.

Mapping Of Alert Text Information

• In case of an inactive alert handling, the alert text information is mapped to the attribute "_original.._text" if the value is inside of an alert range. This mapping is now deactivated by default to increase the performance in Event Manager by about 20%.​
• If necessary for the compatibility of your specific business logic, the previous functionality can be activated again, see Handling of deactivated _alert_hdl Configurations.
