3 Basic System Operation
3.6.5 I/O and Registers in Functions
3-36
Programming Example Using Subscripts
The programming code shown in Fig. 3.11 sets the sum of 100 registers from MW00100 to MW00199
in MW00200 using subscript J.

Table 3.16 Correspondence Between I/O and Registers in Functions
Function I/O Function Register
Bit inputs The bit numbers increase continuously from XB000000 in order of the bit
inputs: XB000000, XB000001, XB000002,
……, XB00000F
Integer, double-length
integer, and real num-
ber inputs The register numbers increase continuously from XW, XL, and XF00001 in
order of the integer, double-length integer, and real number inputs:
XW00001, XW00002, XW00003,
……, XW00016
XL00001, XL00003, XL00005, ……, XL00015
XF00001, XF00003, XF00005, ……, XF00015
Address inputs The address input values correspond to register numbers 0 of the external
register:
Input value = MA00100: MW00100 = AW00000, MW00101 = AW00001...
Bit outputs The bit number increases consecutively from YB000000 in order of bit out-
puts: (YB000000, YB000001, YB000002, YB00000F)
Integer, double-length
integer, and real num-
ber outputs The register numbers increase continuously from YW, YL, and YF00001 in
order of the integer, double-length integer, and real number outputs.
YW00001, YW00002, YW00003, ......, YW00016
YL00001, YL00003, YL00005, ......, YL00015
