Model Conversion Instructions Section 3-33
3-33 Model Conversion Instructions
This section describes instructions used when changing PLC models.
The model conversion instructions provide the same functionality as other
instructions but use BCD data for the operands, like C-series instructions.
(The CP-series use binary data for the operands.) There are five model con-
version 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 operand data.
The model conversion instructions enable converting C-series programs to
CP-series programs without changing the operand data for these instructions.
When converting C-series programs to CP-series programs on CX-Program-
mer (see note), these instructions will be automatically used when converting
(e.g., XFER will be converted to XFERC), eliminating the need to correct
operand data manually.
Note Conversion is achieved by specifying the CP Series as the “device type” in the
Change PLC Dialog Box.

Instructions
“C Series” includes the C200H, C1000H, C2000H, C200HS, C2000HX/HG/
HE(-Z), CQM1, CQM1H, CPM1/CPM1A, CPM2C, and SRM1.
