Precautions for Correct Use
If you set a tag data link with a short packet interval (RPI) when many NX Units are connected
to the EtherNet/IP Slave Terminal, a Tag Data Link Timeout may occur depending on the load
conditions on the EtherNet/IP Slave Terminal. If that occurs, increase the length of the packet
interval (RPI) or reduce the number of NX Units that are mounted.

Select and allocate the originator node's tag set.
• In: Select the originator's input (consume) tag set.
• Out: Select the originator's output (produce) tag set.
Select whether the data is sent in multi-cast or unicast (point-to-point) form.
The default setting is multi-cast.
• Multi-cast connection:
Select when the same data is shared by multiple nodes. This setting is usually
used.
• Point-to-point connection:
Select when the same data is not shared by
multiple nodes. In a unicast connection, other
nodes are not burdened with an unnecessary
load.
Note: Refer to 8-2-2 Creating Tag Data Links on page 8-7 for details on using
multi-cast and unicast connections.
Set the data update cycle (i.e., the packet interval) of each connection between
the originator and target.
• Minimum RPI for the EtherNet/IP Coupler Unit is 4 ms.
• The default setting is 50 ms (i.e., data is updated once every 50 ms).
• The interval can be set to an even number of ms (4, 6, 8,...)
• The interval can be set to between 4 and 1000 ms for the CJ2M-EIP21 and 0.5
and 10,000 ms for other CPU Units in 0.5-ms increments.
Set the time until a connection timeout is detected. 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).
