SIMATIC WinCC Open Architecture Forum

Hello,

I have 78 active S7Plus connections divided into 5 drivers under WinCC OA 3.18 P003 (Linux RHEL 8.4).

¿Is it normal that the overall system consumption is over 22 GB of RAM?

If so, it'd be good to update System Requirements documentation with S7Plus requirements.

Thanks,

The memory consumption seems to be too high.
Can you please check if the memory consumption increases during runtime or if it is already very high directly after startup.
It would be of interest how fast the memory usage increases.

Please get in contact with your common WinCC OA support if you have more detailed information for further analysis.
