1. Overview
1.3.4 Slave Communication
Connecting via V-Link, Modbus RTU, or Modbus TCP/IP is applicable to slave communication using the V9. V-Link and
Modbus RTU are used for serial communication, and Modbus TCP/IP is used for Ethernet (TCP/IP) communication.
V-Link
 “V-Link” is the network where the PC reads from and writes to the internal device memory of the V9 series, memory card
device memory, or PLC1 to 8 device memory using a dedicated protocol.

You can make settings for V-Link communication in [Communication Setting] for the logical ports PLC2 - PLC8.
A communication port is selectable from CN1, MJ1, and MJ2.

For more information, refer to “V-Link” in book 3 of the V9 Series Connection Manual.
MODBUS RTU

The V9 series is connected to a Modbus RTU master via serial connection.

The device memory table for Modbus slave communication is prepared for the V9. The master is allowed to gain access to
the device memory table and read/write the PLC data.
 For more information, refer to the Modbus Slave Communication Specifications manual separately provided.
MODBUS TCP/IP
 The V9 is connected to a Modbus TCP/IP master via Ethernet communication.
 The device memory table for Modbus slave communication is prepared for the V9. The master is allowed to gain access to
the device memory table and read/write the PLC data.
