(Note 1) Figures in the table indicate the number of devices that can be used in the program. The actual inputs and
outputs that can be used vary by configuration.
(Note 2) Operation devices are categorized into "hold type", which memorizes the status immediately before power
failure or switch to the PROG. mode, and "non-hold type", which resets such status. Non-hold area is cleared to
zero when the unit is powered on or the mode is switched between PROG and RUN.
Types of operation devices
Internal relays (R), Data registers (DT), Link relays (L), Link registers
(LD)
Counters (C), Counter set values (CS), Counter elapsed values (CE),
Error alarm relays (E)
Inputs (X), Outputs (Y), Timers (T), Timer set values (TS), Timer
elapsed values (TE), Pulse relays (P), Direct inputs (IN), Direct
outputs (OT), Index registers (I), Unit memories (UM), System data
registers (SD)
(Note 3) Direct inputs (IN), direct outputs (OT), and unit memories (UM) are used by specifying unit slot numbers and
memory addresses to be controlled by instructions.
(Note 4) The number of usable data registers (DT) varies according to the type of CPU and memory configuration
settings.

8.1 CPU Unit Specifications
Register can be used as an address of
memory area and constants modifier.
Data memory for storing timer target
data. It corresponds to the timer number.
Data memory for storing timer elapsed
value. It corresponds to the timer
number.
Data memory for storing counter set
value. It corresponds to the counter
number.
Data memory for storing the elapsed
value during operation of a counter. It
corresponds to the timer number.
