Communications type Standard EtherNet/IP implicit communications (connection-type cyclic commu-
nications)
Setting method After you have set tags, tag sets, and connections with the Network Configura-
tor, you must download 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 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 net-
work variables to the tags.
