Example of a value assignment with checksum:
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.
Complete start-up
The complete start-up procedure for the function is as follows:
1. Create the definition files
2. Set the write protection for the definition files to the value required for
3. Modify the rights to use the cycle directories as follows if the protected
4. Modify the write protection for the cycle directories to the right to use set
Examples
Machine data
Right to use cycle directories:
MD 11160: ACCESS_EXEC_CST = 2
MD 11161: ACCESS_EXEC_CMA = 2
MD 11162: ACCESS_EXEC_CUS = 3
Write protection for cycle directories:
MD 11165: ACCESS_WRITE_CST = 2
MD 11166: ACCESS_WRITE_CMA = 2
MD 11167: ACCESS_WRITE_CUS = 3
Write protection for definition files:
MD 11171: ACCESS_WRITE_MACCESS = 1
MD 11172: ACCESS_WRITE_UACCESS = 3

redefinition as follows using the machine data:

MD 11171: ACCESS_WRITE_MACCESS
MD 11172: ACCESS_WRITE_UACCESS
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
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_CMA Manufacturer's cycles and
MD 11167: ACCESS_WRITE_CUS User cycles
