Scope of functions with WinCC
Performance features
The following tables of performance features help you to assess whether your project
conforms to the system limits of an HMI device.
The specified maximum values are not additive. It cannot be guaranteed that configurations
running on the devices at the full system limits will be functional.
In addition, the complexity of configuring the images, such as number of objects per screen,
number of tag connections, cycle times and scripts, has a decisive influence on the image
opening times and the performance in runtime.
In addition to the specified limits, observe the restrictions imposed by configuration memory
resources.

Note
Observe the notes on using the internal memory
If too many alarms are written to the alarm buffer in short time intervals, the life of the
internal memory and thus the service life of the HMI device will be reduced.
When configuring alarms, observe the notes on the internal memory in the section
"Memory concept (Page 69)".
