*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.
*2 Operation memory area are categorized into "hold type", which memorizes the status immediately
before power failure or switch to the STOP/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
STOP/PROG. mode and RUN mode.
*3 Some internal relay is used. When using internal relays, use unused area.
Refer to 9.5 Special Internal Relay(R).
*4 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.
*5 Some DT register is used. When using DT registers, use unused area.
Refer to 9.3 Data Registers for Data Collection, 9.4 Data Registers for Demand.
