CS/CJ/NSJ Series Instructions Reference Manual (W474)
Note If there is no CS/CJ-series equivalent to the specified CV-series PLC memory address, an error will occur,
the Error Flag will be turned ON, and the address will not be converted.
Hint
• When an Index Register is used as an operand with a “,IR” prefix, the instruction will operate on the
word indicated by the PLC memory address in the Index Register, not the Index Register itself. Once
the desired PLC memory address has been stored in an Index Register, the Index Register itself can
be used as an operand for an instruction.
