What Are Data Links?
Section 5-1
• 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.
• Areas 1 and 2 can be selected from bit-access areas or 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:
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.
The Controller Link Support Board (3G8F7-CLK21-V1 and 3G8F7-CLK23-
E) can be used in automatic data link creation with 1:N allocations, but it
cannot be the startup node. Use a Controller Link Unit (CS1W-CLK21-V1,
CS1W-CLK23, CJ1W-CLK21-V1, or CJ1W-CLK23) on the same network
as the startup node.
4.
For automatic data link creation with 1:N allocations, use the CX-Integra-
tor.
