Introduction		Section 6-1
C200HX/HG/HE PLCs
	Area	Range
	Internal Relay Area 1	IR 000 to IR 235 (See note 1.)
	Special Relay Area 1	SR 236 to SR 255 (See note 1.)
	Special Relay Area 2	SR 256 to SR 299 (See note 1.)
	Internal Relay Area 2	IR 300 to IR 511 (See note 1.)
	Link Relay	LR 00 to LR 63
	Holding Relay	HR 00 to HR 99
	Timer/Counter	T/C 000 to T/C 511
	Auxiliary Relay	AR 00 to AR 27
	DM Area	DM 0000 to DM 6655
	Extended DM Area	EM 0000 to EM 6143 (See note 2.)

Note 1. Words in the Internal Relay Area 1 (IR 000 to IR 235) and Special Relay Area 1 (SR 236 to SR 255) are continuous in memory, and any range of words within these areas can be transferred in a single operation. The same is true for Special Relay Area 2 (SR 256 to SR 299) and Internal Re- lay Area 2 (IR 300 to IR 511). You cannot, however, transfer data in a range that crosses the boundary between Special Relay Area 1 (SR 236 to SR 255) and Special Relay Area 2 (SR 256 to SR 299).

SR 253 to SR 255 cannot be written at the source node, even if they are specified by the RECV instruction’s beginning receive word at the source node.

2.For details on extended DM Area and the number of banks, refer to the op- eration manual for the PLC model that is being used.

CVM1 and CV-series PLCs

Area	Range
	CV500, CVM1-CPU01	CV1000/2000,
		CVM1-CPU11/21
CIO Area	CIO 0000 to CIO 2555
CPU Bus Link Area	G000 to G255 (See note 1.)
Auxiliary Area	A000 to A511 (See note 2.)
Timer Area	T000 to T511	T000 T1023
Counter Area	C000 to C511	C000 to C1023
DM Area	DM0000 to DM8191	DM0000 to DM24575
Expansion DM Area	---	EM00000 to EM32765 (See
		note 3.)

Note 1. Writing is not possible to words G000 through G007 in the CPU Bus Link Area.

2.Writing is not possible to words A256 through A511 in the Auxiliary Area.

3.Expansion DM can be used by mounting an Expansion DM Unit to a CV1000/2000 or CVM1-CPU11/21 PLC. A maximum of eight banks can be used, depending on the type of Expansion DM. For details, refer to the CVM1 and CV-series PLC operation manuals.
