Introduction to Tag Data Links
Tag Data Links
Tag data links enable cyclic tag data exchanges on an EtherNet/IP network between Controllers or be-
tween Controllers and other devices. Variables are assigned to tags.
The settings for tag data links are made with the Sysmac Studio. For the details on the settings, refer
to 7-4-2 Setting Tag Data Links on page 7-17.
With a tag data link, one node requests the connection of a communications line to exchange data
with another node.
The node that requests the connection is called the originator, and the node that receives the request
is called the target.
