Memory utilization
The following table contains typical values for the memory utilization in the integrated
technology. The values refer to a CPU 315T-2 DP with firmware version V3.2 of the
integrated technology:
Base load of the integrated technology
Drive axis
Position axis
Following axis (with one following object)
Following axis (with two following objects)
External encoder
Cams
Measuring input
Cam (empty)
Cam interpolation points*
Cam interpolation points to be interpolated*
Maximum memory utilization
Recommended
* Further explanations can be found in the following calculation example.
Note
With insufficient memory, the Technology CPU goes into STOP mode. Note that these listed
values are only typical values and some commands may temporarily require more memory
during runtime.
If the memory utilization is excessive, online monitoring from S7T Config may no longer be
possible.
Therefore, the recommended calculated maximum memory utilization should not be
exceeded.
