CQM1 Memory Areas
Memory Area Structure
The following memory areas can be used with the CQM1.
Data area Size Words Bits Function
IR area
1
Input area 128 or
256
bits
IR 000 to IR 015 IR 00000 to IR 01515 CQM1-CPU11/21-E: Up to 8 words
(128 bits) can be used for I/O bits. Up to 7
Units can be connected.
CQM1-CPU4@-EV1: Up to 16 words
(256 bits) can be used for I/O bits. Up to 11
Units can be connected.
Output area IR 100 to IR 115 IR 10000 to IR 11515
Work areas 2,720
bits
min.
2
IR 012 to IR 095 IR 01200 to IR 09515 Work bits do not have any specific function,
and they can be freely used within the pro-
gram.
IR 112 to IR 195 IR 11200 to IR 19515
IR 216 to IR 219 IR 21600 to IR 21915
IR 224 to IR 229 IR 22400 to IR 22915
MACRO
operand
area
1
Input area 64 bits IR 096 to IR 099 IR 09600 to IR 09915 Used when the MACRO instruction,
MCRO(99), is used. When the MACRO
instruction is not used, these bits may be
used as work bits.
Output area 64 bits IR 196 to IR 199 IR 19600 to IR 19915
Analog SV area
1
64 bits IR 220 to IR 223 IR 22000 to IR 22315 CQM1-CPU42-EV1:
Used to store the analog set values.
(Cannot be used as work bits.)
Can be used as work bits in other CPU
Units.
High-speed Counter 0
PV
1
32 bits IR 230 to IR 231 IR 23000 to IR 23115 Used to store the present values of high-
speed counter 0.
Port 1 and 2 Pulse Out-
put PVs
1
64 bits IR 236 to IR 239 IR 23600 to IR 23915 CQM1-CPU43-EV1:
Used to store the present values of pulse
outputs for ports 1 and 2.
(Cannot be used as work bits.)
CQM1-CPU44-EV1:
Used by the system.
(Cannot be used as work bits.)
Can be used as work bits in other CPU
Units.
High-speed Counter 1
and 2 PVs
1
64 bits IR 232 to IR 235 IR 23200 to IR 23515 CQM1-CPU43/44-EV1:
Used to store the present values of high-
speed counters 1 and 2 for ports 1 and 2.
(Cannot be used as work bits.)
Can be used as work bits in other CPU
Units.
Expansion Areas

320
bits
IR 200 to IR 215
IR 240 to IR 243
IR 20000 to IR 21515
IR 24000 to IR 24315
These bits are expected to be used in
planned function expansion.
SR area 184
bits
SR 244 to
SR 255
SR 24400 to
SR 25507
These bits serve specific functions such as
flags and control bits.
Can be used as work bits.
TR area 8 bits --- TR 0 to TR 7 These bits are used to temporarily store
ON/OFF status at program branches.
HR area 1,600
bits
HR 00 to HR 99 HR 0000 to HR 9915 These bits store data and retain their ON/
OFF status when power is turned off.
AR area 448
bits
AR 00 to AR 27 AR 0000 to AR 2715 These bits serve specific functions such as
flags and control bits.
