(Refer to 9-3 I/O Memory Alloca-
tion for details.
DM Area DM Area
D00000 to D32767
D20000 to D29599 are used by Special I/O Units,
D30000 to D31599 are used by CPU Bus Units,
and D32000 to D32099 are used by Inner
Boards.
The Error Log is stored in A100 to A199 and the
PLC Setup is stored in the Parameter Area (not a
part of I/O Memory).
Same as shown at left.
EM Area CS/CJ-series CPU Units:
EM Area E00000 to E32767 (13 banks max.)
CJ2-series CPU Units:
EM Area E00000 to E32767 (25 banks max.)
The EM Area in the CS/CJ-series CPU Unit can
be accessed directly by most instructions. (There
is no EM Area in the CP-series CPU Unit.)
Regular instructions can access data in the
current bank or any other bank.
Part of the EM Area can be converted for use as
a file memory.
Same as shown at left.
Timer Area T0000 to T4095 Same as shown at left.
Counter Area C0000 to C4095
(Timer and counter numbers are independent.)
Same as shown at left.
Data Areas
Task Flag Area CS/CJ-series CPU Units: TK0 to TK31
CJ2-series CPU Units: TK0 to TK127
Same as shown at left.
