7 Tag Data Link Functions
7-8
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
The tag data link parameters (e.g., connection information) that are described below are created with
the Network Configurator, and then the parameters are downloaded to all originator devices on the Eth-
erNet/IP network. When the tag data links are used on the EtherNet/IP Unit, use the Network Configu-
rator to make the following settings.
1
Creating the Configuration Information
You can register the EtherNet/IP ports and EtherNet/IP Units to create the connections that
define the tag data links. Refer to the 7-2-3 Registering Devices for details.
2
Setting Tags
Create CPU Unit variables for input (consume) tags and output (produce) tags. You can create
up to 256 tags for an EtherNet/IP Unit on an NJ-series CPU Unit. (There is a maximum data size
of 1,444 bytes (722 words) for each tag.) You can import and export network variables that are
created on the Sysmac Studio to CSV files. This allows you to register them as tags on the Net-
work Configurator. Output tags can be defined to clear output data to 0 or to hold the output data
from before the error when a fatal error occurs in the CPU Unit.
3
Setting Tag Sets
You can create output tag sets and input tag sets and assign tags to them. (You can create a
total of up to eight I/O tag sets.) You can create up to 256 tag sets for an EtherNet/IP Unit on an
NJ-series CPU Unit. (The maximum data size of 1 tag set is 1,444 bytes (722 words).) You can
specify the Controller status in a tag set to indicate the CPU Unit’s operating status (operating
information and error information).
4
Setting Connections
The target device output tag set and the originator device input tag set are associated as con-
nections. You can open a total of up to 32 connections for the EtherNet/IP Unit.
