Siemens SINUMERIK 840DE SL Commissioning Manual

1.9.7 Addressing machine and setting data
Drive and setting data is identified by the character $ followed by the name of the data.
Machine data:
$Mx_<name[index, AX<axis_number>]>
Setting data:
$Sx_<name[index, AX<axis_number>]>
x:
N – General machine or setting data
C – Channel-specific machine or setting data
A – Axis-specific machine or setting data
Index:
For a field, the parameter indicates the index of the data.
AX<axis_number>:
The required axis (<axis_number>) has to be specified for axis-specific data.
Alternatively, the axis index can be read from a local variable using $<variable name>
"substitution characters".
e.g. AX$localvariable
Example:
<DATA name ="$MN_AXCONF_MACHAX_NAME_TAB[0] ">X1</DATA>
Direct addressing of the axis:
<DATA name ="$MA_CTRLOUT_MODULE_NR[0, AX1] ">1</DATA>
…
…
Indirect addressing of the axis:
<LET name ="axisIndex"> 1 </LET>
<DATA name ="$MA_CTRLOUT_MODULE_NR[0, AX$axisIndex] ">1</DATA>
