SINUMERIK 840D/810D Start-Up Guide (IADC) – 03/2006 Edition
Example of a value assignment with checksum:
N18120 $MN_MM_NUM_GUD_NAMES_NCK=20 ’620c
(Checksum 620c preceded by an apostrophe)
When the initialization file is downloaded, there is a check to ensure that the
checksum is valid. If this is the case, the associated value assignment is execu-
ted, even if the access right set on the control is not sufficient.
The complete start-up procedure for the function is as follows:
1. Create the definition files
/_N_DEF_DIR/_N_SACCESS_DEF Siemens system applications
/_N_DEF_DIR/_N_MACCESS_DEF Machine manufacturer or
/_N_DEF_DIR/_N_UACCESS_DEF End user
2. Set the write protection for the definition files to the value required for
redefinition as follows using the machine data:
MD 11170: ACCESS_WRITE_SACCESS Siemens system applications
MD 11171: ACCESS_WRITE_MACCESS Machine manufacturer and
MD 11172: ACCESS_WRITE_UACCESS End user
3. Modify the rights to use the cycle directories as follows if the protected
commands are to be permitted there.
_N_CST_DIR, _N_CMA_DIR and _N_CUS_DIR
via machine data:
MD 11160: ACCESS_EXEC_CST Standard cycles
MD 11161: ACCESS_EXEC_CMA Manufacturer’s cycles and
MD 11162: ACCESS_EXEC_CUS User cycles
4. Modify the write protection for the cycle directories to the right to use set
above as follows so that the implicit right to use the cycle directories cannot
be misused.
_N_CST_DIR, _N_CMA_DIR and _N_CUS_DIR
via machine data:
MD 11165: ACCESS_WRITE_CST Standard cycles
MD 11166: ACCESS_WRITE_CMAManufacturer’s cycles and
MD 11167: ACCESS_WRITE_CUS User cycles
Machine data
Right to use cycle directories: ;
MD 11160: ACCESS_EXEC_CST = 2 ; Machine manufacturer
MD 11161: ACCESS_EXEC_CMA = 2 ; Machine manufacturer
MD 11162: ACCESS_EXEC_CUS = 3 ; End user
Write protection for cycle directories: ;
MD 11165: ACCESS_WRITE_CST = 2 ; Machine manufacturer
MD 11166: ACCESS_WRITE_CMA = 2 ; Machine manufacturer
MD 11167: ACCESS_WRITE_CUS = 3 ; End user
Write protection for definition files: ; set to value
MD 11171: ACCESS_WRITE_MACCESS = 1 ; Machine manufacturer
MD 11172: ACCESS_WRITE_UACCESS = 3 ; End user
