Relation between WINCCOA MANAGER and multi-core

Post by chm0527 »

Hi.
I have a general question about WinccOA manager and Multi-core.


By the manual , 'By design WinCC OA is single-threaded realized. This means that a WinCC OA manager uses only one of these threads'

Through the manual, I understood WINCCOA's managers uses only one thread.


there are 2 questions.
1. So, for example, Is EVENTMANAGER'S one thread occupying only one core until Wincc Program end? Or Is changing cores?
2. Is there a way to fix a specific MANAGER to be allocated only a specific CORE?


Thanks.

Hyemin

Which process is running on which core is managed by the operating system and normally there is no need to change the settings.
After a process is started it can be assigned to a specific core, e.g. by setting the "Affinity" in the Task Manager (Windows). If the process is stopped and restarted the "Affinity" is lost.
