Overview
 One PLC is connected to a maximum of 31 V9 units. The V8, V7, and V6 series can be used together.
-Connection example 1:
-Connection example 2:
 You can make settings for multi-link at the PLC1. For the V9 and V8 series, a physical port is selectable from CN1, MJ1, and 
MJ2. For the V7 or V6 series, however, use CN1 only.
 Only a PLC [Signal Level: RS422/RS485] and with a port number set. RS-485 (2-wire system) connection is adopted to 
connect a V-series unit and a PLC. For available models, see Connection Compatibility List provided at the end of this 
manual.
 Use twisted-pair cables of 0.3 mm sq. or greater between terminal blocks.
 The ladder transfer function is not available for a multi-link connection. 
Maximum length (PLC to the terminating V9) = 500 m
