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.

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.
