S7: Memory configuration
15.4 Configuration of the static user memory
Parts of the static user memory
Passive file system
The following partitions of the passive file system are present in the static user memory:
Partition
U (User)
M (Manufacturer = Machine manufacturer) Files from the _N_CMA_DIR directory (Machine-manufac‐
The free memory of the passive file system displayed in MD18060
$MN_INFO_FREE_MEM_STATIC can be divided among the partitions U and M. The setting
is made via the machine data:
● MD18352 $MN_MM_U_FILE_MEM_SIZE = <memory size for user data>
● MD18353 $MN_MM_M_FILE_MEM_SIZE = <memory size for machine manufacturer data>
Note
Partition S
Partition S (Siemens = Control manufacturer) of the passive file systems is in the dynamic
memory (Page 805).
Active file system
The memory of the active file system is divided into different areas (tool management, global
user data, ...). The size can be set for each area in the machine data that configures memory
(...MM_...).
Free capacity
The size of the free memory is displayed in the machine data:
MD18060 $MN_INFO_FREE_MEM_STATIC
Note
The memory required to expand the memory areas is displayed in the "Startup" area of the
user interface. This information enables the system startup engineer to estimate the actual
memory requirements for the planned expansion.
Memory expansion (option)
If additional static user memory is required, a memory expansion can be purchased as an
option.
You can use the additional memory as required to expand partitions U and/or M or to expand
the memory area of the active file system.
