$SN_... are system variables for NC and machine-specific protection zones.
$SC_... are system variables for channel-specific protection zones.
The index "n" corresponds to the number of the protection zone: 0 = 1. Protection zone
The index "i" corresponds to the number of the contour element: 0 = 1. Contour element
The contour elements must be defined in ascending order.
Note
The system variables of the protection zone definitions are not restored with REORG.
Data of the protection zone definitions
Data storage
The protection zone definitions are stored in the following files:
