Commissioning - Siemens SINUMERIK Series Function Manual

Dynamic user memory
The dynamic NC memory is used jointly by the system and by the user. The area available
to the user is defined as the dynamic user memory.
Dynamic-user-memory size
The size of the dynamic user memory is set in machine data:
MD18210 $MN_MM_USER_MEM_DYNAMIC
Changes are not usually required as an appropriate value is automatically set during the
reconfiguration.
Dynamic user memory still available
The dynamic memory still available is shown in machine data:
MD18050 $MN_INFO_FREE_MEM_DYNAMIC
(free-dynamic-memory display data)
The content of this machine data indicates how much memory is available to expand the
user data areas (local user data, IPO buffer, etc.) for each channel.
