Other Instructions Section 3-31
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.
When an Index Register is used as an operand with a “,IR” prefix, the instruc-
tion 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.
The FRMCV(284) instruction can be used to convert a CV-series program
with the following two kinds of programming for use in a CS/CJ-series PLC.
See the Examples later in this section for an example.
1. When using indirect binary mode DM addressing (*DM)
(when indirectly specifying a data area address with a PLC memory ad-
dress in DM)
2. When using CV-series PLC memory addresses directly as values
(when storing PLC memory addresses in Index Registers with direct ad-
dressing using an instruction such as MOV(021))
