Since some operands are treated as word data and others are treated as bit
data, the meaning of the data in an Index Register will differ depending on the
operand in which it is used.

tion is executed. Caution is required when using instructions like OUT that
are constantly executed. (Refer to 1-1-5 Inputting Data in Operands in
SYSMAC CS/CJ-series Programmable Controllers Instructions Reference
Manual (W340) for details.)
Example:
MOVR(560)
LD
OUT
Above, OUT turns OFF CIO 000013 and IR0 is incremented to indicate
CIO 000014.
MOVR(560)
LD
SET
SET is executed only when the input condition is ON. Thus SET is not ex-
ecuted above and IR0 is not incremented.
MOVR(560)
MOV(021)
When the operand is treated as a word, the contents of the Index Register
are used “as is” as the PLC memory address of a word.
In this example MOVR(560) sets the PLC memory address of CIO 0002 in
IR2 and the MOV(021) instruction copies the contents of D00000 to
CIO 0002.
