OMRON CHAPTER 6 – Converting a C500/C120/C**P Program to CS/CJ/CP/CVM1 Format
CX-Programmer _Page 117
C500/C120/C**P Compare
It is possible to compare UM and DM/HR area data saved in a file and data in a C500/C120/C**P PLC. Select
Tools – C500/C120/CxxP Support – Compare PLC and File.
C500/C120/C**P Operating Mode Change
It is possible to change the operating mode of the connected PLC to RUN, MONITOR, or PROGRAM mode.
Select Tools – C500/C120/CxxP Support – Operating Mode.
Conversion Table for C500/C120/C**P Instructions
When the PLC model is changed using the C500/C120/C**P utility, the programs are automatically converted.
The instructions (mnemonics) and operands are converted so that they function the same way as before
conversion. However, there are some exceptions.
Refer to the Instruction Conversion Table below for the conversion details and the constants used in the
operands. Refer to the Memory Area Conversion Table and Auxiliary Area Conversion Table for the memory
addresses used in the operands.
“CS/CJ Series” in the tables indicates the CJ2H, CS/CJ-H, CJ1M, CS1D, and CP1 PLCs. “CV Series” indicates
CVM1-V2 PLCs.

- The following message will
appear:
“CONVERT_WARNING:
The instruction specification
is different. Check the
instructions.” Check the
specifications of CPU Unit
after conversion.
- These instructions do not
have operands for the
C500/C120/C**P.
- For the CS/CJ-H PLCs,
JMP and JME are
converted to their
corresponding instructions,
JMP0 and JME0,
respectively.
- For the CV Series, a fixed
value #0000 is added as an
operand.

These instructions have
only one operand for the
C500/C120/C**P. After
conversion, a fixed value of
#FFFF is added as the
second operand.
