•There are three types of 1:N allocations.

•Programming Devices (including Programming Consoles) are used to set the automatic data link mode in the DM Parameter Area of the PLC used as the startup node.

•Node 1 is the master node.

•Area 1 can be set in the bit-access areas and area 2 can be set in the DM Area.

•The send area sizes of the master and slave nodes are the same for each area.

•Send nodes are in the same ascending order as node numbers.

•All nodes can be specified to either participate or not participate in the data link.

•The data link areas (data link start words) are common to all nodes partic- ipating in the data links.

Note 1. Automatic data link creation with 1:N allocations can only be used with the following Controller Link Units and Support Boards:

Type	Model
Wired networks	CS1W-CLK21-V1 (for CS Series)
	CJ1W-CLK21-V1 (for CJ Series)
	3G8F7-CLK21-V1 (for PCI bus)

2.Controller Link Units and Support Boards other than those listed above cannot participate in 1:N allocation data links. They can, however, join the network if a parameter in the DM Parameter Area is set so that they do not participate in the data links.

3.For automatic data link creation with 1:N allocations, use the CX-Net in CX- Programmer version 3.2 or higher.
