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.

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.)

Symbols

Type of symbols

Local symbols: Can be used only within a single task in the PLC.

Global symbols: Can be used in all tasks in the PLC.

Network symbols (tags)*7: I/O memory in the CPU Unit can be externally accessed using symbols, depending on parameter settings.
