1.1 Variables
● For access to protected elements from cycles, the execution and write rights for cycle
● The write rights of the local HMI cycle directories must be set to the same protection level
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.
