Refer to
15-2-2 Tag Data Link Bandwidth Usage and RPI
on page 15-9 for the relationship between
the PPS for the device and the PRI.
Transferring the Connection Settings Data
You can synchronize and transfer EtherNet/IP connection settings along with the program data. You
can also transfer all the EtherNet/IP connection settings along with the program data.
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 connection settings are set, it may cause equipment to operate unpredictably.
Even when the correct connection settings are set, make sure that there will be no effect on
equipment before you transfer the data.
• A connection error will result if the network variables that are used in the tag settings are not
set in the Controller. Before downloading the connection settings, check to confirm that the
network variables used in the tag settings are set in the Controller.
• If a communications error occurs, the output status depends on the specifications of the de-
vice 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 and the port on the EtherNet/IP Unit are automatically restarted
after the parameters are downloaded. This restart is required to enable the tag set and con-
nection information. Before you download the parameters, check to confirm that problems will
not occur with the equipment when the port is restarted.
• Do not disconnect the Ethernet cable or reset or turn OFF the power to the EtherNet/IP Unit
during the parameter download.
• The EtherNet/IP connections 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 EtherNet/IP
connections when the connections are stopped or a connection error occurs.
• In the EtherNet/IP network, if the device bandwidth usage (PPS) exceeds the unit's allowable
bandwidth (PPS), the EtherNet/IP connection operations may not agree with the settings.
If you increase the RPI value in such a case, there are cases when the problem can be re-
solved (i.e., the operations agree the settings).
Synchronizing/Transferring a Whole Project
1
Establish an online connection between the computer and the Controller, and then select
Synchronization
from the
Controller
Menu. (Or, click the
Button on the Toolbal.)
