Indirectly Programming Position Attributes (Gp) - Siemens SINUMERIK 840D sl Programming Manual

Examples
Example 1: Settable zero offset (G function group 8)
Program code
N1010 DEF INT INT_VAR
N1020 INT_VAR=2
...
N1090 G[8]=INT_VAR G1 X0 Y0
N1100 INT_VAR=INT_VAR+1
N1110 G[8]=INT_VAR G1 X0 Y0
Example 2: Level selection (G function group 6)
Program code
N2010 R10=$P_GG[6]
...
N2090 G[6]=R10

Indirectly programming position attributes (GP)

Function
Position attributes, e.g. the incremental or absolute programming of the axis position, can be
indirectly programmed as variables in conjunction with the key word
Application
The indirect programming of position attributes is used in replacement cycles, as in this
case, the following advantage exists over programming position attributes as keyword (e.g.
,
IC
As a result of the indirect programming as variable, no
would otherwise branch for all possible position attributes.
Syntax
<POSITIONING COMMAND>[<axis/spindle>]=
GP(<position>,<position attribute)
<axis/spindle>=BP(<position>,<position attribute)
