Data Areas
Index Registers
IR0 to IR15
Same as shown at left.
Data Registers
DR0 to DR15
Same as shown at left.
Arithmetic Flags
(such as RE and
EQ)
Condition Flags:
In the CS/CJ-series CPU Unit these Flags are in
a separate area and are specified by labels
rather than addresses. With the
CX-Programmer, these are specified using
global symbols, such as “P_Instr_Error “ and
“P_Equals." With a Programming Console, they
are specified using “ER,” “=,” etc.
Same as shown at left.
(The Programming Console can
not be used.)
Clock Pulses
Clock Pulses:
In the CS/CJ-series CPU Unit these pulses are in
a separate area and are specified by labels such
as “1s” and “0.1s” rather than addresses.
Same as shown at left.
PLC setup
Special Area
In the CS/CJ/CP-series CPU Unit, the PLC Setup
is not stored in the DM Area, but a separate area
(the Parameter Area) which is not a part of I/O
memory.
The PLC Setup is edited with CX-Programmer in
a table format and user-friendly dialogue.
Individual PLC Setup addresses can also be
edited with a Programming Console.
Same as shown at left.
(The Programming Console can
not be used.)

9-3 I/O Memory Alloca-
tion.

Available for LD, LD NOT, AND, AND NOT, OR,
OR NOT, OUT, OUT NOT, RSET, SET, KEEP,
DIFU, DIFD, CMP, CPS, and MOV

formed.)

Instruction operand data
format
Basically operands are specified in binary.
In XFER(070), for example, the number of words
is specified in binary (0001 to FFFF or 1 to
65,535 decimal). Specifying data in binary in-
creases the setting range about six-fold.
Same as shown at left.
Specifying operands requiring
multiple words
If an operand requiring multiple words is speci-
fied at the end of an area so that there are not
enough words left in the area for the operand, the
instruction can be executed and the Error Flag
will not turn ON. The program, however, is
checked when transferred from the
CX-Programmer to the CPU Unit and cannot be
transferred with incorrect operand specifications.
Such programs also cannot be read from the
CPU Unit.
Same as shown at left.
