Startup - Siemens SINUMERIK 840D sl Function Manual

Memory Configuration (S7)
15.3 Configuration of the static user memory
Memory space for active file system
The memory space for the active file system is divided into various data areas (tool
management, global user data, etc.), which can be defined individually using machine data.
The memory still available is shown in machine data:
MD18060 $MN_INFO_FREE_MEM_STATIC
(free-static-memory display data)
You can expand the sizes of the individual memory areas for the active file system with the
relevant machine data until the available memory has been used.
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)
The machine manufacturer can also acquire additional static user memory ("Expansion of
buffered CNC user memory" option).
You can use the additional memory space as required to expand partitions U and M or to
expand the memory area of the active file system.

Startup

Procedure
1. Load standard machine data.
2. If you have selected the "Expansion of buffered CNC user memory" option:
3. Preset machine data:
MD18230 $MN_MM_USER_MEM_BUFFERED
with a high value (> default memory available + optional additional memory).
4. Reset the NCK.
Default values are entered in all other memory-configuration machine data.
5. Set the sizes of partitions U and M in machine data:
MD18352 $MN_MM_U_FILE_MEM_SIZE
(end-user memory for part programs/cycles/files)
MD18353 $MN_MM_M_FILE_MEM_SIZE
(memory size for cycles/files of the machine manufacturer)
6. Activate the number of required channels and axes.
918
Activate the option.
Alarm 6030 "User memory limit adjusted" is triggered and the maximum memory
available for the user is entered in MD18230 (including optional memory expansion).
