5 Understanding Programming
Direct Addressing of Index Registers
The size of an index registers is two words per register for Index Registers IR0 to IR15, so use a
double-word instruction (with an "L" in the mnemonic).

Mnemonic Primary function
MOVR(560) Stores the PLC memory
address of a bit or word in an
MOVRW(561)
Index Register.
SETR(635)
GETR(636) Outputs the PLC memory
address stored in an Index
Register.
RSRCH@ Outputs the first PLC mem-
ory address of the matching

to 384)
RSORT@ Outputs one higher than the
PLC memory address of the

MOVL(498) Transfers between Index
Registers. Used for
XCGL(562)
exchanges and comparisons.

CMPL(060)
Changes the PLC memory
address in the Index Register
−−L(593)
by incrementing, decrement-
ing, or offsetting its content.
+L(401)
−L(411)
FRMCV(284) Convert actual PLC memory
addresses between
CVM1/CV-series and CJ-
TOCV(285)
series addresses.
