Automatic Setting, 1:N
Allocations
Allocations
This method is used to simplify the establishment of 1:N allocation data links
between master and slave nodes.
between master and slave nodes.
• 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.
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:

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.
