Range Description
Input to a function.
XW00016
Bit input: XB000000 to XB00000F
Integer input: XW00001 to
Double-length integer input:
Register number nnnnn is expressed
as a decimal number.
Output from a function.
YW00016
Bit output: YB000000 to YB00000F
Integer output: YW00001 to
Double-length integer output:
Register number nnnnn is expressed
as a decimal number.
ZW00000 to Internal registers unique to each func-
ZW00063 tion. Can be used in the function for
internal processes. Register number
nnnnn is expressed as a decimal num-
ber.
AW00000 to External registers that use the address
AW32767 input value as the base address. For
linking with S, M, I, O, #, and
DAnnnnn registers. Register number
nnnnn is expressed as a decimal num-
ber.
#W00000 to Registers that can only be read by a
#W16383 function. Can be used only by the
corresponding function. The actual
range used is specified by the user on
the MPE720. Register number nnnnn
is expressed as a decimal number.
DW00000 to Internal registers unique to each func-
DW16383 tion. Can be used only by the corre-
sponding function. The actual range
used is specified by the user on the
MPE720. Register number nnnnn is
expressed as a decimal number.
Same as the registers for drawings.
These registers can be called from any drawings or function. Use
them carefully when the same function is called from drawings
with different priority levels.
