Overview Of Definable And Redefinable Attributes - Siemens SINUMERIK 840D sl Programming Manual

Work preparation
3.1 Flexible NC programming
3. For access to protected elements from cycles, the execution and write rights for cycle
directories _N_CST_DIR, _N_CMA_DIR, and _N_CST_DIR have to be modified.
Execution rights
– MD11160 $MN_ACCESS_EXEC_CST = <protection level>
– MD11161 $MN_ACCESS_EXEC_CMA = <protection level>
– MD11162 $MN_ACCESS_EXEC_CUS = <protection level>
Write rights
– MD11165 $MN_ACCESS_WRITE_CST = <protection level>
– MD11166 $MN_ACCESS_WRITE_CMA = <protection level>
– MD11167 MN_ACCESS_WRITE_CUS = <protection level>
The execution right has to be set to at least the same protection level as the highest
protection level of the element used.
The write right must be set to at least the same protection level as the execution right.
4. The write rights of the local HMI cycle directories must be set to the same protection level
as the local NC cycle directories.
Subprogram calls in ACCESS files
To structure access protection further, subprograms (SPF or MPF identifier) can be called in
ACCESS files. The subprograms inherit the execution rights of the calling ACCESS file.
Note
Only access rights can be redefined in the ACCESS files. All other attributes have to continue
to be programmed/redefined in the corresponding definition files.
