The dynamic (DRAM) or static (SRAM) memory available depends on the hard-
ware configuration of the components used (PCU and MCI board) and the
memory available for SINUMERIK 840Di sl.
PCU 50.3–C/1.5 GHz
PCU 50.3–P/2.0 GHz
MCI board
1) DRAM component (main memory) occupied by SINUMERIK 840Di sl
and thus no longer available for Windows XP.
2) The SRAM memory of the MCI board is divided into:
– Part programs and manufacturer cycles: 3 MB
– User data: 1 MB
– Siemens cycles: 1 MB
The individual memory areas of the user data are set to reasonable default val-
ues during general reset of the NCK. To obtain optimum utilization of the user
memory the size of the individual data areas can be set for, e.g.:
S
Part programs
S
Tool management
S
Tool offsets
S
User data
S
Arithmetic variables
S
Compensations
S
Protection zones
S
Frames
(see Section 11.4.2, Page 11-308):
The memory must be sectionalized before commencement of the actual NCK
commissioning because all user data (e.g. part programs, tool offsets) will be
lost during the changes.
Machine data, setting data, and option data are not lost when the memory is
reorganized.
The machine data of the memory configuration are activated by power ON.
