Access rights in relation to OPI (APRB, APWB)
The access rights (APRB, APWB) restrict access to system and user variables via the OPI
equally for all system components (HMI, PLC, external computers, EPS services, etc.).
Note
Local HMI access rights
When changing access rights to system data, care must be taken to ensure that such
changes are consistent with the access rights defined using HMI mechanisms.
APR/APW access attributes
For compatibility reasons, attributes APR and APW are implicitly mapped to the attributes APRP
/ APRB and APWP / APWB:
•
APR x
•
APW y
Setting access rights using ACCESS files
When using ACCESS files to assign access rights, redefinitions of access rights for system
data, user data, and NC language commands may only continue to be programmed in these
ACCESS files. Global user data (GUD) is an exception. For this data, access rights have to
continue to be redefined (if this appears necessary) in the corresponding definition files.

During part program processing the end user password has to be set.
The cycle has to be stored in the _N_CUS_DIR (user), _N_CMA_DIR or _N_CST_DIR
directory.
The execution rights must be set to at least end user for the _N_CUS_DIR,
_N_CMA_DIR or _N_CST_DIR directories in machine data MD11162
$MN_ACCESS_EXEC_CUS, MD11161 $MN_ACCESS_EXEC_CMA or MD11160
$MN_ACCESS_EXEC_CST respectively.
During part program processing the key-operated switch must be set to 3 ... 0.
The cycle has to be stored in the _N_CUS_DIR, _N_CMA_DIR or _N_CST_DIR
directory.
The execution rights must be set to at least the corresponding key-operated switch
position for the _N_CUS_DIR, _N_CMA_DIR or _N_CST_DIR directories in machine
data MD11162 $MN_ACCESS_EXEC_CUS, MD11161 $MN_ACCESS_EXEC_CMA or
MD11160 $MN_ACCESS_EXEC_CST respectively.
