• The following registers are saved in flash memory.
• M registers
• C registers
• # registers (Saved with the user program.)
• D registers (Saved with the user program.)
Type Name Designation Method Range Description Characteristic
S System registers SB, SW, SL, SFnnnnn
(SAnnnnn) SW00000 to
SW01023 System registers provided by the sys-
tem. Register number nnnnn is
expressed as a decimal number. When
the system is started, SW00000 to
SW00049 are cleared to 0. Common to all
drawings
M Data registers MB, MW, ML,
MFnnnnn (MAnnnnn) MW00000 to
MW32767 Data registers are shared by all draw-
ings. Used as interfaces between draw-
ings. Register number nnnnn is
expressed as a decimal number.
I Input registers IB, IW, IL, IFhhhh
(IAhhhh) IW0000 to
IW07FF Registers used for input data.
Register number hhhh is expressed as a
hexadecimal number.
O Output registers OB, OW, OL, OFhhhh
(OAhhhh) OW0000 to
OW07FF Registers used for output data.
Register number hhhh is expressed as a
hexadecimal number.
C Constant registers CB, CW, CL, CFnnnnn
(CAnnnnn) CW00000 to
CW32767 Constant registers can be called only in
the program. Register number nnnnn is
expressed as a decimal number.
# # registers #B, #W, #L, #Fnnnnn
(Annnnn) #W00000 to
#W16383 # registers can be called only in the
program and can be used only in the
corresponding drawing.
The actual range used is specified by
the user on the CP-717. Register num-
ber nnnnn is expressed as a decimal
number. Unique to each
drawing
D D registers DB, DW, DL, DFnnnnn
(DAnnnnn) DW00000 to
DW16383 D registers are unique to each drawing
and can be used only in the corre-
sponding drawing.
