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). |

EM Area |
32k words/bank ´ 25 banks max.: E00_00000 to E18_32767 max. *1 *2
*1. Bits in the EM Area can be addressed either by bit or by word. These bits cannot be addressed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not specifically support the CJ2 CPU Units. *2. EM banks D to 18 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not specifically support the CJ2 CPU Units. *3. Force-set/reset to the EM Area is enabled by specifying a start bank in parameter settings. (unit version 1.2 or higher) |

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 enabled in this mode. RUN Mode: Programs are executed. This is the normal operating mode. |
