CVM1 and CV-series PLCs
	Setting item			Setting range

	PLC model		Set the model of the PLC’s CPU Unit.

	Nodes		1 to 32
			Set the address of the refresh nodes.
			It cannot be set to a parameter exceeding the “maximum node
			address” of the network parameter.

	First data link sta-		Set the first word to store data link status. An area of 16 words is
	tus word		used.
			CIO Area: CIO 0001 to CIO 2540 (*1)
			LR Area: LR 000 to LR 184 (*2)
			DM Area:	DM 0000 to DM 8176 (CV500/CVM1-CPU01-EV@)
				DM 0000 to DM 24560 (Other CPU Units)
			EM Area:	Banks 00 to 07, EM 0000 to EM 32750
				(EM must be installed)
			*1: When CIO 000 is specified or when the default setting (– – –
			– –) is left unchanged, the default first status word will be
			used. Refer to 5-4 Checking Data Link Status for details.
			*2: When a word between LR 000 and LR 184 is specified, the
			data link area will be allocated between CIO 1000 and
			CIO 1184.

	Area 1	Data link	CIO Area: CIO 0000 to CIO 2555
		start word	LR Area: LR 000 to LR 199 (*)
			LR Area: LR 000 to LR 199 (*)
			DM Area:	DM 0000 to DM 8191 (CV500/CVM1-CPU01-EV@)
				DM 0000 to DM 24575 (Other CPU Units)
			EM Area:	Banks 00 to 07, EM 0000 to EM 32765
				(EM must be installed)
			The same area cannot be set for both area 1 and area 2. Set dif-
			ferent areas.
			*: When a word between LR 000 and LR 199 is specified, the
			data link area will be allocated between CIO 1000 and
			CIO 1199.

		Number of	Remote nodes: 0 to the number of source words
		words		Set the number of words to be received.
			Local node:	0 to 1,000
				Set the number of words to be transmitted.
			The total number of words in area 1 and area 2 in each node
			must not exceed 1,000.
			The numbers of words in both area 1 and area 2 in each node
			must not be set to 0.

		Offset	Remote nodes: 0 to one less than number of source words
				Set the offset for the data to be received.
			Local node:	Cannot be set.
			This setting is not required if an offset is not used.
