Appendix 2 n : 1 Connection (Multi-link 2) App2-3
* When the terminal converter “TC485” is not used, install jumpers between +RD/+SD and
−RD/−SD.
For V706:
For V706 + DU-01, refer to “For V7 Series:” above.
(a) Connection between PLC ↔ V706 master station (MJ2)
The communication parameter setting and connecting method are the same as those for 1 : 1
connection.
(Refer to “Chapter 2” to “Chapter 33.”)
(b) Connection between V706 master station (MJ1) ↔ V706 slave station (MJ2)
The connecting port of the V706 master station should be MJ1. Select [Modular Jack] from the
[System Setting] menu. Select [Multi-Link] for [Modular Jack 1].
The multi-link 2 master cable (b) (V6-MLT) is 3 m long.
From the M706 master station, the V6-MLT cable is connected to the terminal block. From the
terminal block, cables are routed in the direction of “(c)” and “(d).”
(C) Connection between terminal block ↔ V706 slave station (MJ2)
The connecting port of the V706 slave station should be MJ2.
A V6-TMP cable (3 m long) is used as cable “(c).”
Since MJ2 is adapted to 4-wire connection, it is necessary to change the signal connection
from 4-wire to 2-wire for multi-link 2 connection. Connect the slave station to the terminal
block via 4-wire connection and then install jumpers between +SD and +RD and between −SD
and −RD on the terminal block (as shown in the wiring diagram on the following page).
