Holding Area

8,192 bits (512 words): Words H000 to H511

Bits in this area maintain their ON/OFF status when PLC 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

*

* A960 to A1471 and A10000 to A11535 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and

Support Software that do not specifically support the CJ2 CPU Units.

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.)

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.

*1. Force-setting/resetting bits in the EM Area is possible only for banks specified for the EM Area force-set/reset function.
