Item Description
Connection I/O Type When creating tag data links for a CS1W-EIP21, CJ1W-EIP21,
CJ2B-EIP21, or CJ2M-EIP21, select Input Only (Tag Type).
When creating tag data links for other target devices, select
the connection I/O type specified in that device’s EDS file.
Use the Input Only (ID type) setting when another company's
node is the originator and does not support connection set-
tings with a Tag type setting.
Connection Type Selects whether the data is sent in multicast or unicast (point-
to-point). The default setting is multicast.
• Multicast connection
Select this type when the same data is shared by multiple
nodes. This setting is usually used.
• Point-to-Point connection
Select this type when the same data is not shared by multiple
nodes. In a unicast connection, other nodes are not bur-
dened with an unnecessary load.
Note Refer to 6-1-2 Overview of Operation for details on
using multicast and unicast connection as well as count-
ing the number of connections.
The Connection Structure Field and the following items will not be displayed if the
Hide Detail Button is pressed.
Packet Interval (RPI) Sets the data update cycle (i.e., the packet interval) of each
connection between the originator and target. The interval can
be set to between 1 and 10,000 ms for the CJ2M and 0.5 and
10,000 ms for other CPU Units in 0.5-ms increments. The
default setting is 50 ms (i.e., data updated once every 50 ms).
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).
Connection Name Sets a name for the connection. (32 characters max.)
