Instance ID and tag name
An instance ID and tag name are cyclic data ID numbers for communicating with the external device.
■Instance ID
An instance ID is an ID number for cyclic data defined in an EDS file.
It is mainly used for communications with an adapter, and cyclic data is set individually for each instance ID. (operating status,
current value, sensor output, and other data)
When multiple connections are made to the same adapter, an instance ID can be set individually for each connection.
By using the EDS file for each device, connection settings can be made without being aware of an instance ID in "EtherNet/IP
Configuration".

module .
*1 Since the CC-Link IE TSN Plus module EDS file is registered as the initial setting in "EtherNet/IP Configuration", it is not necessary to
perform a new registration when the CC-Link IE TSN Plus module is the originator. For details regarding the originator setting method
when using another device as the originator, refer to the separate device manual.
*2 For the instance ID specified when performing instance communications targeting the CC-Link IE TSN Plus module, refer to the
following.

■Tag name
A tag name is an ID number related to the tag settings registered in the external device.
It is mainly used when the external device is a scanner. Cyclic data to be used for communications is determined based on the
tag name registered in the external device.
At first, as tag settings, the external device registers in itself the tag name and the combination of the tag name and the device
assigned to it.
Then, when the CC-Link IE TSN Plus module opens a connection for the tag of the external device, the external device sends
the data of the assigned device to the CC-Link IE TSN Plus module at the RPI interval.
When the CC-Link IE TSN Plus module is not the external device, for details on how to set the tag to the
external device, refer to the manual for the external device.
