1.3 Connection Methods
1-25
n: 1 Connection (Multi-link2 (Ethernet)) (Under Development)
Overview

One PLC is connected to a maximum of 32 V9 units. The V8 series can be used together.

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.
- Connection example
 You can make settings for 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.

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 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 : 1 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 multi-link2 (Ethernet) connection.
