Hi.
We are currently working on a project and we have encountered a problem with the WINCCOA 3.17 modbus driver.
Currently we have about 2000 variables configured in the same 1000ms Pollgroup.These variables have been configured with archives to store data every certain time. Minimum 30s
The number of devices connected to this driver is 32.
The problem comes that this driver is increasing the Ram resources of the system, currently are 7 gigabyte, until it reaches a point that the system has no more resources and this goes into emergency mode.
Is the consumption of this driver normal, or can there be a error in the configuration?
Thank you for your assistance.
Best regards

We do not know about a problem with the memory usage of the Modbus driver.
For the analysis we need more detailed information. Therefore please get in contact with your common WinCC OA support.
