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.
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.
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.

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.
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.
