3.5 Defining protection levels for user data (GUD)
Explanation
APR n Read access protection
APW n Write access protection
n Protection level n from 0/10 (highest
level) to 7/17 (lowest level)
APW 0-7, APR 0-7:
The module variables cannot be written or read via
the NC program or in MDA mode.
APW 10-17, APR 10-17:
The module variables can still be written or read via
the NC program or in MDA mode.
Protection levels
0/10 = SIEMENS
1/11 = OEM_ HIGH
2/12 = OEM _LOW
3/13 = end user
4/14 to 7/17 = keyswitch position 3 to 0
Note
The command input sequence is as follows:
APR.. APW..
Any other sequence represents a syntax error.
In order to protect a complete file, the commands
must be entered in the first line of the file!
Function
Access criteria can be defined for GUD modules to
protect them against manipulation. Using such
criteria, for example, it is possible to inhibit changes
to cycles that the machine manufacturer has set up
as GUD modules.
The access protection applies to all variables
defined in this module.
When an attempt is made to access protected data,
the control outputs an appropriate alarm.
