I/O Memory Areas
Data can be read and written to I/O memory from the ladder programs. I/O memory consists of an area for I/O with external devices, user areas,
and system areas.
I/O Memory Areas
Name
No. of bits
Word addresses
Remarks
CIO Area
Input Bits
1,600 bits (100 words)
CIO 0 to CIO 99
For NA-type, CIO90, CIO91 is occupied by analog input 0, 1.
Output Bits
1,600 bits (100 words)
CIO 100 to CIO 199 For NA-type, CIO190 is occupied by analog output 0.
Serial PLC Link Words
1,440 bits (90 words)
CIO 200 to CIO 289
--
Work Area (W)
1,600 bits (100 words)
W0 to W99
--
Holding Area (H)
800 bits (50 words)
H0 to H49
Data in this area is retained during power interruptions if a
Battery Set (sold separately) is mounted to an N/NA-type CPU
Unit.
Data Memory Area (D)
E-type CPU Unit
2K words
D0 to D2047
Data in specified words of the DM Area can be retained in the
built-in EEPROM in the backup memory by using a bit in the
Auxiliary Area.
Applicable words: D0 to D1499
(One word can be specified at a time.)
N/NA-type CPU Unit
8K words
D0 to D8191
Data in specified words of the DM Area can be retained in the
built-in EEPROM in the backup memory by using a bit in the
Auxiliary Area.
Applicable words: D0 to D6999
(One word can be specified at a time.)
