Bits
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.
Work bits do not have any specific function,
and they can be freely used within the pro-
gram.
Used when the MACRO instruction,
MCRO(99), is used. When the MACRO
instruction is not used, these bits may be
used as work bits.
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.
Used to store the present values of high-
speed counter 0.
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.
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.
These bits are expected to be used in
planned function expansion.
These bits serve specific functions such as
flags and control bits.
Can be used as work bits.
These bits are used to temporarily store
ON/OFF status at program branches.
These bits store data and retain their ON/
OFF status when power is turned off.
These bits serve specific functions such as
flags and control bits.
