Variables
EXTORG
Returns the active absolute zero offset. The values returned by the variable are identical for both
possible expressions of absolute zero offsets.
This read-only variable interrupts block preparation and may be read from the CNC, from the PLC
and from DNC.
The values of the EXTORG variables that correspond to the absolute zero offsets are:
Considerations:
• When programming only an incremental zero offset (G58 or G59), the value of the EXTORG
variable will be 0.
• When programming an absolute and an incremental zero offset, the EXTORG variable will keep
the value of the absolute zero offset.
Example: If G54 + G58, EXTORG = 1 has been programmed.
Read-and-write variables
ORG(X-C)n
This variable allows the value of the selected axis to be read or modified in the table corresponding
to the indicated zero offset (n).
PLCOF(X-C)
This variable allows the value of the selected axis to be read or modified in the table of additive offsets
indicated by the PLC.
Accessing any of the PLCOF(X-C) variables interrupts block preparation and the CNC waits for that
command to be executed before resuming block preparation.

10 G159N10
If G54-G59 is used:
(P110=ORGX 55)
Loads parameter P100 with the X value of G55 in the zero offset table.
(ORGY 54=100.8)
It assigns value 100.8 to the Y axis in the table for the G54 zero offset.
If G159N1-N20 is used:
(P110=ORGX 19)
Loads parameter P110 with the X value of G159N19 in the zero offset table.
(ORGY 19=100.8)
It assigns value 100.8 to the Y axis in the table for the G159N19 zero offset.
