Note
For specific application methods, refer to
The following table shows the data formats that the CP2E CPU Units can handle.
Auto-
increment
The contents of IR
is incremented
by +1 or +2 after referencing the
value as an PLC memory address.
+1: Specify ,IR
+
+2: Specify ,IR
+ +
,IR0++
LD ,IR0 ++
Increments the contents of IR0 by 2 after
the bit with the PLC memory address in IR0
is loaded.
,IR1+
MOV #0001 ,IR1 +
Increments the contents of IR1 by 1 after
#0001 is stored in the word with the PLC
memory address in IR1.
Auto-dec-
rement
The contents of IR
is decremented
by -1 or -2 after referencing the
value as an PLC memory address.
-1: Specify ,-IR
-2: Specify ,--IR
,--IR0
LD ,--IR0
After decrementing the contents of IR0 by
2, the bit with the PLC memory address in
IR0 is loaded.
,-IR1
MOV #0001 ,-IR1
After decrementing the contents of IR1 by
1, #0001 is stored in the word with the PLC
memory address in IR1.

binary
The data is treated as 16-bit signed binary data using the leftmost bit as the
sign bit. The value is expressed in 4-digit hexadecimal.
Positive numbers: If the leftmost bit is OFF, it indicates a non-negative value.
For 4-digit hexadecimal, the value will be 0000 to 7FFF hex.
Negative numbers: If the leftmost bit is ON, it indicates a negative value. For 4-
digit hexadecimal, the value be
8
000 to FFFF hex. It will be expressed as the
2
’
s complement of the absolute value of the negative value (decimal).
