Note
Redefinition of reading rights of machine data
The protection level for reading machine data can only be set with keyword APR for the
part program and OPI.
The keywords APRP and APRB are not supported by the redefinition of the reading
rights, and result in alarm 12490 "Access right APRP/APRB <protection level> was not
set".
Note
During redefinition the access right can be freely assigned to a variable between the
lowest protection level 7 and the dedicated protection level, e.g. 1 (machine
manufacturer).
