Example 1: Converting a CV-series Program with

DM Indirect Binary
Mode DM Addressing
In this FRMCV(284) example, a DM word is specified in S, the PLC memory
address there is stored in an Index Register, and the Index Register is used
for indirectly addressed.

PLC Setup
Indirect DM data:
When indirect DM addresses are in binary, the content of
the DM word is treated as a PLC memory address and
specifies the corresponding address in I/O memory.
• CV-series program
(Program using indirect DM
binary mode addressing)
• CS/CJ-series program
Equivalent program
In this case, the value in D00000 is 0200 hex. The
corresponding data area address is CIO 0512, so
#1234 is transferred to CIO 0512.
Word address:
D00000
Word address:
CIO 0512
MOV(021)
CS/CJ-series PLC
memory address
CS/CJ-series PLC
memory address
In this case, the value in D00000 is 0200 hex. The
corresponding CV-series data area address is CIO 0512.
The CS/CJ-series PLC memory address for CIO 0512 is
0000C200 hex, so this value is stored in IR0. The
destination operand in MOV(021) indirectly addresses the
content of IR0, so #1234 is transferred to CIO 0512.
