Setting Description
Connection I/O Type Select Input Only (T
ag type) to use tag data links with a CS1W-EIP21,
CJ1W-EIP21, CJ2B-EIP21, CJ2M-EIP21, CJ1W-EIP21(CJ2), CJ1W-
EIP21(NJ), NX701, NX102-££££, NX1P2, NJ501-££££, NJ301-££
££ or NJ101 CPU Unit.
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 set-
ting.
In/Out The connection's I/O is automatically displayed based on the selected
connection.
Input Only: Just In is displayed.
Target Variable Select the target node's tag set to assign.
• In: Select the target's output (produce) tag set.
• Out: Select the target's input (consume) tag set.
Originator Variable Select the originator node's tag set to assign.
• In: Select the originator's input (consume) tag set.
• Out: Select the originator's output (produce) tag set.
Connection Type 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
transmission, other nodes are not burdened with an unnecessary load.
Refer to 7-1-4 Overview of Operation on page 7-7 for details on using mul-
ti-cast and unicast connections, and counting the number of connections.
RPI Set the data update cycle (i.e., the packet interval) of each connection be-
tween the originator and target.
The default setting is 50 ms (i.e., data is updated once every 50 ms).
• NX701 CPU Unit:
Set the RPI between 0.5 and 10,000 ms in 0.5-ms increments.
• NX102 CPU Unit:
Set the RPI between 1 and 10,000 ms in 1-ms increments.
• NX1P2 CPU Unit:
Set the RPI between 2 and 10,000 ms in 0.5-ms increments.
• NJ-series CPU Unit:
Set the RPI between 1 and 10,000 ms in 1-ms increments.
*1
Timeout Value Set the time elapsed 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).
*1. For CPU unit version 1.02 or earlier, you can set the RPI between 10 and 10,000 ms in 1-ms incre-
ments.
2 After you make all of the settings, Click the OK Button.
