I/O Bits 2,560 bits

Processing Speed Overhead Processing Time Normal Mode: 200 μs

(If tag data links are used with EtherNet/IP, add the following to the above time: 100 μs + Number of

transferred words × 0.33 μs)

Execution Time Basic Instructions: 0.016 μs min.;

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.

Maximum Number of Expansion Racks 3 max.

CIO Area I/O Area 2,560 bits (160 words): Words CIO 0000 to CIO 0159

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

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)

• 7,168 bits (448 words): Words A0 to A447

• 24,576 bits (1,536 words): Words A10000 to A11535

Read/write: 16,384 bits (1,024 words) in words A448 to A1471

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)

Force-set/reset Enabled

Banks

EM3 EM3 EM6 to EM9 EM7 to EME EM11 to EM18

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.

Execution Mode Normal Mode
