Internal registers unique to each function.
ZW00000 to
Can be used for function internal process-
ZW00063
ing.
External registers with the address input
value as the base address.
AW00000 to
AW32767
For linking with S, M, I, O, #, and
DAnnnnn.
Call-only registers.
#W00000 to
Can be called only from the relevant
#W16383
function. The usage range is set by the
user using MPE720.
Internal registers unique to each function.
DW00000 to
Can be called only the relevant function.
DW16383
The usage range is set by the user using
MPE720.
Same as DWG registers.
These registers are shared by drawings and functions. Pay attention to
how these registers are to be used when calling the same function from a
drawing of a different priority level.
