3. n : 1 Connection (Multi-link 2)
• One PLC is connected to a maximum of four V606e units.
• An original network is created where the V606e (Local Port 1) that is directly connected to the PLC
is the master station, and other three V606e units are slave stations. Only the master station
makes communications directly with the PLC, and the slave stations make communications with
the PLC via the master station.
• Communications between the V606e master station and the PLC depend on the communication
speed set on the PLC. The maximum available speed for the V606e is 57600 bps, which is higher
than the one available with multi-link connection described in “4. n : 1 Connection (Multi-link).”
• This multi-link connection is available with almost all the PLC models that support 1 : 1 connection
(refer to the Appendix).
(The connection between the master station and the PLC is the same as the one for 1 : 1
connection.)
• Use the RS-485 2-wire connection between stations of the V606e. Please use Hakko Electronics’
multi-link 2 master cable (V6-MLT) for connection between the master station (Local Port 1) and
the slave station (Local Port 2).
• The V606e and V6 series can be used together. The V6 series can be the master station.
(However, when V606e/V606/V606i is the master station, the slave station must be
V606e/V606/V606i. Also, depending on the hardware version of the V6 series, multi-link 2
connection may not be supported. Refer to the V6 Hardware Specifications.)
• For more information on wiring and communication settings, refer to the PLC Connection Manual.
