Memory Configuration (S7)
15.1
Brief description
Memory types
To store and manage data, the NC requires a static memory and a dynamic memory:
● Static NC memory
● Dynamic NC memory
Memory organization
The memory areas of the individual data groups in the static and dynamic NC memories
have defined sizes, which are fixed when the memory is configured.
This type of memory organization ensures the deterministic behavior of the control:
The reserved memory area is guaranteed throughout part program processing.
Memory configuration
When booted for the first time, the system enters default values in all other memory-
configuration machine data. This configuration is adequate in most cases. However, the
machine manufacturer/user can make changes at any time (Reconfiguration).

Function Manual, 03/2009, 6FC5397-1BP10-4BA0
In the static NC memory, the program data (part programs, cycles, etc.) and the current
system and user data (tool management, global user data, etc.) is saved to persistent
memory.
In the dynamic NC memory the data is saved to non-persistent memory. The data
here concerns information generated by the NC that is only required for a limited time
(e.g. macros, local user data, interpolation buffer, etc.).
