9-5-7 Tag Data Parameters and Specifications
To make tag data links, you must download tag data link parameters, such as tag set settings and con-
nection settings, to all devices in the EtherNet/IP network. When the download operation is executed,
the tag data link parameters are transferred to the EtherNet/IP Units that require the settings.
The following procedure shows how to download the tag data link parameters.
Additional Information
Refer to the CS and CJ Series EtherNet/IP Units Operation Manual (Cat. No. W465) for more
for information on how to connect the Network Configurator online.
Precautions for Correct Use
• If the node addresses (IP addresses) are not set correctly, you may connect to the wrong
Controller and set incorrect device parameters. Download data only after you confirm that
you are connected to the correct Controller.
• If incorrect tag data link parameters are set, it may cause equipment to operate unpredict-
ably. Even when the correct tag data link parameters are set, make sure that there will be no
effect on equipment before you transfer the data.
• When network variables are used in tag settings, a connection error will result if the variables
are not also set in the CPU Unit. Before downloading the tag data link parameters, check to
confirm that the network variables are set in the CPU Unit. Check whether the network vari-
able, tag, and connection settings are correct.
• If a communications error occurs, the output status depends on the specifications of the
device being used. When a communications error occurs for a device that is used along with
output devices, check the operating specifications and implement safety countermeasures.
• The EtherNet/IP Unit is automatically restarted after the parameters are downloaded. This
restart is required to enable the tag set and connection information. Before you download the
parameters, check to confirm that problems will not occur with the equipment when the Unit
is restarted.
9-5-7 Tag Data Parameters and Specifications
Item Specification
Communications type Standard EtherNet/IP implicit communications (connection-type cyclic communications)
Setting method After you have set the tags, tag sets, and connections with the Network Configurator,
you must download the tag data link parameters to all devices on the EtherNet/IP net-
work.
After the parameters are downloaded, the EtherNet/IP Units are restarted to start the
tag data links.
EtherNet/IP Coupler
tag size
Input tag size: 1 to 504 Bytes
Output tag size: 0 to 504 Bytes
Tag sets Number of tags per tag set: 1 maximum
Connection type Each connection can be set for 1-to-1 (unicast) or 1-to-N (multicast) communications.
Default setting: Multicast
Packet interval (RPI) The packet interval can be set separately for each connection.
Timeout Value Sets the time until a connection times out. The timeout value is set as a multiple of the
packet interval (RPI) and can be set to 4, 8, 16, 32, 64, 128, 256, or 512 times the
packet interval. The default setting is 4 times the packet interval (RPI).
