Np_Index - Siemens SINUMERIK 840D sl Function Manual

Example
The initialization status of the 6th protection area is set to "P" (preactivated or PLC-controlled):
Program code
N100 $NP_INIT_STAT[5] = "P"
The current status depends on the state of the interface signal parameterized in
$NP_BIT_NO (Page 228).

$NP_INDEX

Function
For automatic protection areas ($NP_PROT_TYPE (Page 224)), the address, under which the
geometric data of the machine part, tool, etc. to be protected is saved, should be entered in
the system variable. The control then automatically creates the geometrical dimensions of the
protection area from the geometric data.
Example
For example, for an automatic tool protection area ($NP_PROT_TYPE == "TOOL") the
geometrical dimensions of the protection area are created based on the tool data.
Syntax
$NP_INDEX[<m>,<i>] = <value>
Meaning
$NP_INDEX:
<m>:
<i>:
<value>:
