Memory Configuration - Siemens SINUMERIK 840Di sl Commissioning Manual

11.4

Memory configuration

Hardware configuration
The dynamic (DRAM) or static (SRAM) memory available depends on the hardware
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 is thus no
longer available for Windows NT.
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
User data
The individual memory areas of the user data are set to reasonable default values during
general reset of the NC. To obtain optimum utilization of the user memory, the size of the
individual data areas can be set for, e.g.:
● Part programs
● Tool management
● Tool offsets
● User data
● R parameters
● Compensations
● Protection zones
● Frames
(See Subsection "SRAM memory" (Page 383))
The memory must be sectionalized before commencement of the actual NC commissioning,
because all user data (e.g. part programs, tool offsets) will be lost during a change.
Machine data, setting data, and option data are not lost when the memory is reorganized.
Activation
The machine data of the memory configuration are activated by power ON.
