Term Explanation and Definition
Tag data link A function that enables cyclic tag data exchanges on an EtherNet/IP
network between PLCs or between PLCs and with other devices without
using a user program in the PLCs.
Tag A tag is a unit that is used to exchange data with tag data links. Data is
exchanged between the local network variables and remote network
variables specified in the tags or between specified I/O memory areas.
Tag set When a connection is established, from 1 to 8 tags (including Controller
status) is configured as a tag set. Each tag set represents the data that
is linked for a tag data link connection.
Connection A connection is used to exchange data as a unit within which data
synchronicity is maintained.
Thus, data synchronicity is maintained for all the data exchanged for the
tags in one data set.
Originator and Target To perform tag data links, one node requests the opening of a
communications line called "connection" to perform tag data links.
The node that requests opening the connection is called "originator",
and the node that receives the request is called "target".
Node With EtherNet/IP network, 1 node is 1 EtherNet/IP port.
Tag data link
parameter
The tag data link parameter is the setting data to perform the tag data
link. It includes the data to set tags, tag sets, and connections.
EDS file A file that contains the I/O points of EtherNet/IP devices and the
parameters that can be set via EtherNet/IP.
