Controlling Operation and Outputting Data with an
Ethernet Connection
Data Exchange with EtherNet/IP
Data is exchanged cyclically between Ethernet devices on the EtherNet/IP network using tag data links as
shown below.
● Data Exchange Method
To exchange data, a connection is opened between two EtherNet/IP devices.
One of the nodes requests the connection to open a connection with a remote node.
The node that requests the connection is called the originator, and the node that receives the request is called
the target.
● Data Exchange Memory Locations
The memory locations that are used to exchange data across a connection are specified as tags.
You can specify memory addresses or variables for tags.
A group of tags consists of an output tag set and an input tag set.
To communicate by EtherNet/IP with a PLC that does not support tag data link communication, use the message
communication function rather than tag data link.
