(Note 1) Figures in the table indicate the number of devices that can be used in a program. The actual number
of input/output points that can be used varies depending on the 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 the 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 Setting of hold or non-hold type
Internal relay (R), Data register (DT), Link relay (L), Link
register (LD)
Can be specified as a hold or non-hold
type, using the tool software.
Counter (C), Counter set value (CS), Counter set value
(CE), Error alarm relay (E)
Hold type
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)
Non-hold type
(Note 3) Direct input (IN), direct output (OT), and unit memory (UM) are used by specifying unit slot numbers
and memory addresses to be controlled by instructions.
