1. Overview
n : n Connection (1: n Multi-link2 (Ethernet)) (Under Development)
Overview
 A maximum of 32 units of V9 series can be connected to a maximum of 31 units of PLCs.
 Multi-link2 (Ethernet) enables you to establish an original network consisting of a master V9 of local port No. 1 and slave
V9 units of local port Nos. 2 to 32. The master V9 communicates with the PLC directly, and the slave V9 units
communicate with the PLC through the master.
 You can make settings for 1 : n multi-link2 (Ethernet) in [Communication Setting] for PLC1. Therefore, multi-link2
connection is not possible concurrently with a network connection that uses a “CUR-xx” communication interface unit.

1 : n multi-link2 (Ethernet) enables sharing of data stored in PLC1 device memory among the V9 units. However, sharing
data in PLC2 - PLC8 is not possible.

The V7 and V6 series cannot be used together.
 The communication speed between the master station and the PLC depends on the setting made on the PLC; however,
communication among V9 units is performed via Ethernet, thus, high-speed communication is possible among them.
 For PLCs that support 1 : n multi-link2 (Ethernet) connection, see Connection Compatibility List provided at the end of this
manual.
The connection between the master and the PLC is the same as the one for 1 : n connection.
Ethernet connection is adopted to connect a master with slaves.

If the master station becomes faulty (communication error), the master and slave stations do not work, and as a result,
“Communication Error Time-Out” is displayed. If a slave station becomes faulty, “Data Loading...” is displayed due to a
communication error only on the faulty station.
 The ladder transfer function is not available for a 1 : n multi-link2 (Ethernet) connection.
