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. Refer to
ing the Network Configurator to the Network
for information on how to Connect the Network Configura-
tor online.
Precautions for Correct Use
Precautions for Correct Use
•
If the node addresses (IP addresses) are not set correctly, you may connect to the wrong Con-
troller 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 unpredictably.
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 Controller. Before downloading the tag data link parameters, check to
confirm that the network variables are set in the Controller. Check whether the network vari-
able, tag, and connection settings are correct. On the Connection and Tag Status Tab Pages
described in
14-1-1 Starting the Device Monitoring
•
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 built-in EtherNet/IP port 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
port is restarted.
•
Make sure that the major CIP revision of the device registered with the Network Configurator
is the same as the major CIP revision of the NY-series Controller that you use. If major CIP
revisions are not the same, the parameters may not be downloaded. To determine whether
downloading is possible, refer to
•
Do not disconnect the Ethernet cable during the parameter download.
•
Tag data links (data exchange) between relevant nodes is stopped during a download. Before
you download data in RUN mode, make sure that it will not affect the controlled system. Also
implement interlocks on data processing in ladder programming that uses tag data links when
the tag data links are stopped or a tag data link error occurs.
