System variables: Protection area elements for automatic tool protection areas

The protection area element of an automatic tool protection area is defined using the
subsequent system variables. The control automatically generates the values of the system
variables from the geometric data of the associated tool, and these can only be read.
Name
$NP_T_NAME[<n>]
$NP_T_TYPE[<n>]
$NP_T_FILENAME[<n>]

1) n = 0, 1, ... ($MN_MM_MAXNUM_3D_T_PROT_ELEM – 1)
2) The system variables of the automatic tool protection areas correspond to those of the machine
protection areas.
