Setting Data Links		Section 5-2
	Item	Setting range
	Send size (number of	Set the number of words in BCD between 0 and 1,000.
	words) for node of area 1	The total number of send words for area 1 and area 2
		must not exceed 1,000.
		When area 1 is not used, set to 0.
	Area 2 data link start	Set the word address in BCD.
	word	DM Area: DM 0000 to DM 5999
		EM Area: Banks 00 to 15, EM 0000 to EM 6143
	Area 2 type	Set the area type for area 2 in BCD.
		DM Area: 82
		EM Area: Banks 00 to 07: 90 to 97
		Banks 08 to 15: A8 to AF
		Area 2 not used: 00
	Send size (number of	Set the number of words in BCD between 0 and 1,000.
	words) for node of area 2	The total number of send words of area 1 and area 2
		must not exceed 1,000.
		When area 2 is not used, set to 0.
	First data link status word	Set in BCD the first word used for storing data link status.
		An area of 16 words is used for storing status.
		0 (*), IR 001 to IR 220, IR 300 to IR 496
		Status is stored in the IR or CIO Area only.
		*: When 0 is set, status of nodes 1 to 6 is stored in
		CIO 239 to CIO 241 for level 0 and in CIO 243 to CIO
		245 for level 1.
	Nodes to participate in	Set to ON (1) the bits corresponding to the nodes partici-
	the data links	pating in the data links.
		The data link will not start unless the startup node itself is
		set as a participating node.
		The data link will not start if the node is set to a parameter
		exceeding the “maximum node address” of the network
		parameter.

Note a) The total number of words in data link send and receive areas must not exceed 8,000 per node.

b)The following values must be satisfied for each node for the data link area 1 and area 2 so that the final word in the data link does not go beyond the last word in the PLC memory area.

(Data link start word – 1) + Total number of send/receive words in area ≤ 235 (First word IR 000 to IR 235)

511 (First word IR 300 to IR 511)

63 (LR Area)

5999 (DM Area)

6143 (EM Area)

c)When using area 1 only, set the data link start word, type, and the number of send words of area 2 to 0.

d)When using area 2 only, set the data link start word, type, and the number of send words of area 1 to 0.

e)The startup node must be set as a participating node of the data links. If not, the data links will not start.
