8,192 bits (512 words): Words W000 to W511
Cannot be used for external I/O.
Holding Area
8,192 bits (512 words): Words H000 to H511
Bits in this area maintain their ON/OFF status when PLC is turned OFF or operating mode is changed.
Words H512 to H1535: These words can be used only for function blocks. They can be used only for function
block instances (i.e., they are allocated only for internal variables in function blocks).

Force-setting/resetting is enabled only for areas specified for automatic address allocation.
Index Registers
IR0 to IR15
These are special registers for storing PLC memory addresses for indirect addressing. (Index Registers can
be set so that they are unique in each task or so that they are shared by all tasks.)
Cyclic Task Flag Area
128 flags
Memory Card
128 MB, 256 MB, or 512 MB
Operating Modes
PROGRAM Mode: Programs are not executed. Preparations can be executed prior to program execution in
this mode.
MONITOR Mode: Programs are executed, and some operations, such as online editing, and changes to
present values in I/O memory, are enabled in this mode.
RUN Mode:
Programs are executed. This is the normal operating mode.

tasks)
Number of Tasks
Cyclic tasks: 128
Interrupt tasks: 256
(Interrupt tasks can be defined as cyclic tasks to create extra cyclic tasks. Therefore, the total number of cyclic
tasks is actually 384 max.)
