The settings are as follows:
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
setting.
Connection Type Select whether the data is sent in multicast or unicast (point-to-point)
form. The default setting is multicast.
• 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 uni-
cast 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
multi-cast and unicast connections, and counting the number of connec-
tions.
