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 en-
abled in this mode.
RUN mode: Programs are executed. This is the normal operating mode.
Execution mode Normal mode

Tasks Type of tasks Cyclic tasks
Interrupt tasks (Power OFF interrupt tasks, scheduled interrupt tasks, I/O interrupt tasks, and external interrupt 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.)
