App2-6 Appendix 2 n : 1 Connection (Multi-link 2)
For V706:
• The terminating resistance of the V706 should be set on the DIP switch.
• When the PLC and the master station are connected via RS-422/485, set the terminating
resistance at the PLC and the master station (MJ2).
• When the V706 (master and slave stations) are connected via RS-485 (2-wire), set the terminating
resistance at the V706 master station (MJ1) and the terminating slave station (MJ2).
Terminating Resistance Setting Example
1. When the PLC is connected to V706 master station via RS-232C:
V-SFT Setting
The following settings must be made on the V-SFT editor.
Only the points different from those described in “V-SFT Setting (1 : 1 Connection)” (page 1-10) are
explained here.
PLC Selection
Select the PLC that is connected.
• Setting Procedure
