4,800 (300 words): CIO 120000 to CIO 149915 (words
CIO 1200 to CIO 1499)
37,504 (2,344 words): CIO 380000 to CIO 614315 (words
CIO 3800 to CIO 6143)
These bits in the CIO Area are used as work bits in pro-
gramming to control program execution. They cannot be
used for external I/O.
8,192 bits (512 words): W00000 to W51115 (W000 to
W511)
These bits are used to control the programs only. (I/O
from external I/O is not possible.)
When using work bits in programming, use the bits in the
Work Area first before using bits from other areas.
8,192 bits (512 words): H00000 to H51115 (H000 to
H511)
Holding bits are used to control the execution of the pro-
gram, and maintain their ON/OFF status when the PLC is
turned OFF or the operating mode is changed.
Read only: 7,168 bits (448 words): A00000 to A44715
(words A000 to A447)
Read/write: 8,192 bits (512 words): A44800 to A95915
(words A448 to A959)
Auxiliary bits are allocated for specific functions.
16 bits (TR0 to TR15)
Temporary bits are used to temporarily store the ON/OFF
execution conditions at program branches.
4,096: T0000 to T4095 (used for timers only)
4,096: C0000 to C4095 (used for counters only)
32 Kwords: D00000 to D32767
Used as a general-purpose data area for reading and
writing data in word units (16 bits). Words in the DM Area
maintain their status when the PLC is turned OFF or the
operating mode is changed.
Special I/O Unit DM Area: D20000 to D29599 (100 words
Used to set parameters for Special I/O Units.
CPU Bus Unit DM Area: D30000 to D31599 (100 words
16 Units)
Used to set parameters for CPU Bus Units.
Inner Board DM Area: D32000 to D32099
Used to set parameters for Inner Boards (Single CPU
Systems or Process-control CPU Units only).
32 Kwords per bank, 13 banks max.: E0_00000 to
EC_32767 max. (Not available on some CPU Units.)
Used as a general-purpose data area for reading and
writing data in word units (16 bits). Words in the EM Area
maintain their status when the PLC is turned OFF or the
operating mode is changed.
The EM Area is divided into banks, and the addresses
can be set by either of the following methods.
Changing the current bank using the EMBC(281) instruc-
tion and setting addresses for the current bank.
Setting bank numbers and addresses directly.
EM data can be stored in files by specifying the number
of the first bank.
