Type: Automatic tool protection area ($NP_PROT_TYPE == "TOOL")
<i>
1) TOA area "1" can be addressed with 0 as well as also with 1.
Example
The 6th protection area is an automatic tool protection area ($NP_PROT_TYPE == "TOOL").
The geometrical dimensions of the protection area should be generated from the geometric
data of the tool at the following tool location:
● Tool location number: 1
● Magazine number: 9998 (spindle 1)
● TOA area: 1
Tool management is active.
Program code
; The dimensions of the 6th protection area are based on the tool data
; of the tool located at the following position:
N100 $NP_INDEX[5,0] = 1
N110 $NP_INDEX[5,1] = 9998
N120 $NP_INDEX[5,2] = 1
