Np_Prot_Name - Siemens SINUMERIK 840D sl Function Manual

K8: Geometric machine modeling - only 840D sl
6.2 Commissioning
The system variables are described in detail in the following sections.
Note
Establish a defined initial state
It is recommended that a defined initial state be generated before parameterizing the protection
areas. To do this, set the system variables of the protection areas to their default values with
the DELOBJ() (Page 205) function.
Change system variable values
If the value of one of the system variables listed above is changed, the change becomes
immediately visible at the user interface, e.g. SINUMERIK Operate. The machine model of the
NC is only updated after explicitly requesting that the machine model is recalculated by calling
the PROTA() (Page 277) or PROTS() (Page 278) function.
6.2.3.2

$NP_PROT_NAME

Function
Enter the NC-wide unique protection area name in the system variable. The protection area
is referenced via this name, e.g. by a protection area element. The name is also displayed in
the graphical editor of SINUMERIK Operate.
Syntax
$NP_PROT_NAME[<m>] = "<name>"
Meaning
$NP_PROT_NAME:
<m>:
<name>:
Example
The 6th protection area is assigned the name "Spindle":
Program code
N100 $NP_PROT_NAME[5] = "Spindle"
222
