What Are Data Links?
Section 5-1
Manual Setting Options
The following options can be set when manually setting data links.
Offsets
Data of the only the specified number of words can be received starting from
the specified word position. The starting word is set as an offset from the
beginning of the send data. The following is an example.
Easy Setting
The send data areas of all nodes can be set to the same size (same as for
automatic setting described next).
Automatically Setting Data Links
Automatic setting can be used to create simple data links.
• Using a Programming Device (such as a Programming Console), set the
automatic data link mode in the DM parameter area of the startup node.
• Area 1 can be selected from bit areas (i.e., IR, CIO, and LR areas) and
Area 2 can be selected from Data Memory.
• In areas 1 and 2 send areas for each node are of the same size.
• Send nodes are in the same ascending order as node numbers.
• It is not possible to receive only a part of send data.
• All nodes can be specified to either participate or not participate in the
data link.
• The data link areas are exactly the same and common to all nodes partic-
ipating in the data links.
Note The Controller Link Support Software contains a function called
“Easy Setting” that can be used within the manual data link mode to
register the same data links as automatic setting. The “Easy Setting”
