Setting Description
Connection I/O Type Select Input Only (tag type) to use tag data links with a CS1W-EIP21, CJ1W-
EIP21, CJ2B-EIP21, CJ2M-EIP21, CJ1W-EIP21 (CJ2), CJ1W-EIP21 (NJ),
NJ301-
@@@@ , or NJ501- @@@@ . When you create tag data links for other
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 settings with a Tag type setting.
Connection Type Select whether the data is sent in multi-cast or unicast (point-to-point) format.
The default setting is multi-cast.
• Multi-cast connection: Select when the same data is shared by multi-
ple nodes. This setting is usually used.
• Point-to-Point connection: Select when the same data is not shared by
multiple nodes. In a unicast transmission,
other nodes are not burdened with an unnec-
essary load.
Note Refer to 7-1-4 Overview of Operation for details on using multi-cast and
unicast connections, and counting the number of connections.
The Connection Structure Area and the following items are not displayed if the Hide Detail Button is clicked.
Packet Interval (RPI) Set the data update cycle (i.e., the packet interval) of each connection
between the originator and target.
You can set an interval to between 0.5 and 10,000 ms in 0.5-ms increments
(NJ-series Controllers: between 10 and 10,000 ms in 1-ms increments).
The default setting is 50 ms (i.e., data is updated once every 50 ms).
Timeout Value 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).
Connection Name Set a name for the connection. (32 single-byte characters max.)
