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)

Cannot be used for external I/O.
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).
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

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

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.
