Term Explanation and Definition

Node A controller and a device are connected to an EtherNet/IP network via

EtherNet/IP ports. EtherNet/IP recognizes each EtherNet/IP port

connected to the network as one node.

When a device with two EtherNet/IP ports is connected to the

EtherNet/IP network, EtherNet/IP recognizes this device as two nodes.

EtherNet/IP achieves the communications between controllers or the

communications between a controller and a device by exchanging data

between these nodes connected to the network.

Tag A minimum unit of the data that is exchanged on the EtherNet/IP network

is called a tag. The tag is defined as a network variable or as a physical

address, and it is assigned to the memory area of each device.

Tag set In the EtherNet/IP network, a data unit that consists of two or more tags

can be exchanged. The data unit consisting of two or more tags for the

data exchange is called a tag set. Up to eight tags can be configured per

tag set for OMRON controllers.

Tag data link In EtherNet/IP, the tag and tag set can be exchanged cyclically between

nodes without using a user program.

This standard feature on EtherNet/IP is called a tag data link.

Connection A connection is used to exchange data as a unit within which data

concurrency is maintained. The connection consists of tags or tag sets.

Creating the concurrent tag data link between the specified nodes is

called a "connection establishment". When the connection is

established, the tags or tag sets that configure the connection are

exchanged between the specified nodes concurrently.

There are two ways to specify the connection: one is to specify a tag set

name (tag name), and the other is to specify an instance number of

Assembly Object. In Sysmac Studio, the connection is set by specifying

the instance number.

Connection type There are two kinds of connection types for the tag data link connection.

One is a multi-cast connection, and the other is a unicast (point-to-point)

connection. The multi-cast connection sends an output tag set in one

packet to more than one node. The unicast connection separately sends

one output tag set to each node. Therefore, multi-cast connections can

decrease the communications load if one output tag set is sent to more

than one node.

．

Terms and Definitions

Term Explanation and Definition

Originator and

Target To operate tag data links, one node requests the opening of a

communications line called a "connection".

The node that requests to open the connection is called an "originator",

and the node that receives the request is called a "target".

Each communication data is called an ''originator variable'' and a ''target

variable''.

In Sysmac Studio, the instance number is specified in the target variable.

Tag data link

parameter A tag data link parameter is the setting data to operate tag data links.

It includes the data to set tags, tag sets, and connections.

EDS file A file that describes the number of I/O points for the EtherNet/IP device

and the parameters that can be set via EtherNet/IP.

RPI This is an abbreviation for Requested Packet Interval.

RPI indicates the data I/O refresh cycle that is set for each connection

between the originator and the target.
