Setting Data Links		Section 5-2
	Item	Setting range
	Area start word	Set the word address in BCD.
		IR or CIO Area: 0 to 6143
		LR Area: LR 000 to LR 199 (1000 to 1199) (*)
		DM Area: DM 0 to 32767
		EM Area: Banks 0 to 12 EM 0 to 32767
		*: When a word between LR 000 and LR 199 is speci-
		fied, the data link area will be allocated between
		words 1000 and 1199 in the IR or CIO Area.
	Area	Set the area type of area 1 as a hexadecimal number.
		IR Area: 80 Hex
		LR Area: 86 Hex
		DM Area: 82 Hex
		EM Area Banks 0 to 7: 90 to 97 Hex
		Banks 8 to 12: A8 to AC Hex
	Number of master com-	Set the number of words in BCD between 0 and 1,000.
	mon send words	The number of common send words per master node
		added to the number of delivery send words per node
		must not exceed 1,000.
		Set to 0 if common data is not to be sent from a master
		node to a slave node.
	No. of receive and send	Set the number of words in BCD between 0 and 1,000.
	words per node	The number of common send words per master node
		added to the number of delivery send words per node
		must not exceed 1,000.
		Set to 0 if delivery data is not to be sent.
	First word to store data	Set in BCD the first word used for storing data link status.
	link status	When automatic setup is used, status can be stored in
		the IR or CIO Area only. The number of words used to
		store status depends on the data link status storage for-
		mat specification as below.
		0 (*)
		1 to 6128 (32 nodes max., 8-bit format: 16 words used)
		*: When 0 is set, the status is saved in IR 1500 + unit
		number x 25 (+ 7 to + 22).
	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.

Note 1. Node 1 becomes the master node. Node 1 must be registered as a partic- ipating node.

2.Only one area can be specified when using the chain type of 1:N alloca- tion.

3.The startup node (the node that sets the above DM parameter and starts the data link) must be set as a participating node of the data link. If not, the data links will not start.

4.The total number of words in data link send and receive areas must not ex- ceed 20,000 per node when using Controller Link Units with unit Ver. 1.2 or later, or 12,000 words per node if using pre-Ver. 1.2 Controller Link Units. The total number of words in data link send and receive areas of a master node must satisfy the following values. Since the number of master node words is greatest when 1:N allocation is used, the value can be esti- mated from the number of master node words.
