Setting Tag Data Links
The following table describes the various settings in the dialog box.
Setting
Target Device Selects the target device.
Connection Any name can be given to the connection (up to 32 charac-
Name ters).
If this field is left blank, a default name will be assigned.
This Connection Name can be used for comments.
Connection I/O When making tag data links in a CS1W-EIP21, CJ1W-EIP21,
Type CJ2B-EIP21, or CJ2M-EIP21, select Input Only (Tag type).
When making tag data links in other devices, select the con-
nection 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 the Tag type setting.
In/Out The connections I/O is automatically displayed based on the
selected connection.
• Input Only: Just In is displayed.
Target Variable Selects and allocates the target node's tag set.
• In: Selects the target's output (produce) tag set.
• Out: Selects the target's input (consume) tag set.
Originator Vari- Selects and allocates the originator node's tag set.
able
• In: Selects the originator's output (produce) tag set.
• Out: Selects the originator's input (consume) tag set.
Connection Selects whether the data is sent in a multicast or unicast. The
Type default setting is multicast.
• Multicast connection:
Select when the same data is shared by multiple nodes. This
setting is usually selected.
• Point-to-Point connection:
Select when the same data is not being shared by multiple
nodes. In a unicast transmission, other nodes are not bur-
dened with an unnecessary load.
Note Refer to 6-1-2 Overview of Operation for details on
RPI Sets the packet interval (RPI) of each connection between the
originator and target. The interval can be set between 1 and
10,000 ms for the CJ2M-EIP21 and 0.5 and 10,000 ms for
other CPU Units in 0.5-ms units. The default setting is 50 ms
(data refreshed once every 50 ms).
Timeout Value Sets the time until a connection timeout is detected. The time
out value is set as a multiple of the packet interval (RPI) and
can be set to a 4, 8, 16, 32, 64, 128, 256, or 512 multiple. The
default setting is 4× the packet interval (RPI).
2. When the settings are completed, click the OK Button.
Function
using multicast and unicast transmissions, and counting
the number of connections.
