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
	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)

•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)
EM Area		32k words/bank × 25 banks max.: E00_00000 to E18_32767 max.
		(Bits in the EM Area can be addressed either by bit or by word.)
		32K words × 4		32K words × 4	32K words × 10	32K words × 15	32K words × 25
		banks		banks	banks	banks	banks
	Force-set/reset Enabled	EM3		EM3	EM6 to EM9	EM7 to EME	EM11 to EM18
	Banks
		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
