The model conversion instructions provide the same functionality as other
instructions but use BCD data for the operands, like C-series instructions.
(The CJ/CS-series use binary data for the operands.) There are five model
conversion instructions, as shown in the above table, all of which have a C
added to the end of the mnemonic of the equivalent function for binary oper-
and data.
The model conversion instructions enable converting C-series programs to
CS/CJ-series programs without changing the operand data for these instruc-
tions.
When converting C-series programs to CS/CJ-series programs on CX-Pro-
grammer version 5.0 or higher (see note), these instructions will be automati-
cally used when converting (e.g., XFER will be converted to XFERC),
eliminating the need to correct operand data manually.
When converting C-series programs to CS/CJ-series programs on CX-Pro-
grammer version 4.0 or lower (see note), any operand for which a constant is
specified will be converted from BCD to binary, but any operand data for
which a word address is specified will have to be corrected manually.
Note Conversion is achieved by specifying the CS/CJ Series as the "device type" in
the Change PLC Dialog Box.
"C Series" includes the C200H, C1000H, C2000H, C200HS, C2000HX/HG/
HE(-Z), CQM1, CQM1H, CPM1/CPM1A, CPM2C, and SRM1.

Same Converted to XFER. If a word
address is specified for the
first operand (number of words
to transfer), it will need to be
corrected manually to binary
data in the program.
Same Converted to DIST. If a word
(distribution address is specified for the
operation and third operand (offset data), it
stack push will need to be corrected man-
operation) ually to binary data in the pro-
gram.
Same Converted to COLL. If a word
(data collection address is specified for the
operation and second operand (offset data),
stack read it will need to be corrected
operation) manually to binary data in the
program.
Same Converted to MOVB. If a word
address is specified for the
second operand (control data),
it will need to be corrected
manually to binary data in the
program.
Same Converted to BCNT. If a word
address is specified for the
first operand (number of words
to count), it will need to be cor-
rected manually to binary data
in the program.
