Special Instructions: 0.048 μs min.

Interrupt Task Start Time

30 μs

Maximum Number of Connectable Units

Total per CPU Rack or Expansion Rack: 10 Units max.;

Total per PAC: 40 Units max.

Link Area

3,200 bits (200 words): Words CIO 1000 to CIO 1199

CPU Bus Unit Area

6,400 bits (400 words): Words CIO 1500 to CIO 1899

Special I/O Unit Area

15,360 bits (960 words): Words CIO 2000 to CIO 2959

DeviceNet Area

9,600 bits (600 words): Words CIO 3200 to CIO 3799

Internal I/O Area

3,200 bits (200 words): Words CIO 1300 to CIO 1499

37,504 bits (2,344 words): Words CIO 3800 to CIO 6143

Cannot be used for external I/O.

Work Area

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 PAC 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).

Auxiliary Area

Read-only: 31,744 bits (1,984 words)

Temporary Area

16 bits: TR0 to TR15

Timer Area

4,096 timer numbers (T0000 to T4095 (separate from counters))

Counter Area

4,096 counter numbers (C0000 to C4095 (separate from timers))

DM Area

32k words (Bits in the DM Area can be addressed either by bit or by word.)

DM Area words for Special I/O Units: D20000 to D29599 (100 words × 96 Units)

DM Area words for CPU Bus Units: D30000 to D31599 (100 words × 16 Units)

EM Area

32k words/bank × 25 banks max.: E00_00000 to E18_32767 max.

Force-setting/resetting is enabled only for areas specified for automatic address allocation.

Index Registers

IR0 to IR15

These are special registers for storing PAC 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.
