7 Tag Data Link Functions
7-6
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
Note
To enable a connection, each tag set must include only input tags or only output tags. (Both input and output
tags cannot be included in the same tag set.)
The tag data link and performance specifications of the NJ-series CPU Unit are given below.
*1
To specify a specific I/O memory address for a tag, create a variable, use an AT specification of the I/O mem-
ory address on the Sysmac Studio, and then specify the variable with the AT specification for the tag.
*2
You can import network variables created in the Sysmac Studio to the Network Configurator as tags.
However, variables with a Network Publish attribute that have variable names that are the same as the I/O
memory address notation, such as “0000” and “H0000” are not exported to CSV files.
*3
The following table lists the variables that you can specify as tags.

Tag Data Link Functions and Specifications
Item
Specification
Communications type
Standard EtherNet/IP implicit communications (connection-type cyclic communi-
cations)
Setting method
After you have set the tags, tag sets, and connections with the Network Configu-
rator, you must download the tag data link parameters to all devices on the Eth-
erNet/IP network.
You can export the network variables that you created on the Sysmac Studio to
a CSV file. You can then import the file to the Network Configurator and assign
the network variables to tags.
After the parameters are downloaded, the EtherNet/IP Units are restarted to
start the tag data links.
