Tag Data Link Functions and Specifications

The tag data link and performance specifications of the NJ/NX-series CPU Unit are given below.
Item
Communications type
Setting method
*1 Supported variable types You can specify the following network variables as tags.
Tags
Maximum number of
words per tag
Maximum number of
tags
Tag sets Maximum number of
tags per tag set
Maximum number of
words per tag set
Maximum number of tag
sets
Connections
Connection type
Packet interval (RPI)
Permissible communications band (pps)
*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. (This
applies only for the NJ-series CPU Units.) For an NX1P2 CPU Unit, you need to set CJ memory to use I/O
memory address. For details on CJ memory setting, refer to the NJ/NX-series CPU Unit Software User's Man-
ual (Cat. No. W501).
*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.

Standard EtherNet/IP implicit communications (connection-type cyclic commu-
nications)
After you have set the tags, tag sets, and connections with the Network Config-
urator, you must download the tag data link parameters to all devices on the
EtherNet/IP network. After the parameters are downloaded, the EtherNet/IP
Units are restarted to start the tag data links.
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.
