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.
