iO-GRID m and KV-Nano Series Modbus RTU Connection

2302EN V2.0.0 and KV-Nano Series Modbus RTU Connection
Operating Manual

1. Remote I/O Module System Configuration List

The following table shows the specifications and descriptions of
the remote I/O module system components:

1.1 Product Description

The remote I/O system consists of a main controller
(GFMS-RM01S), digital input module (GFDI-RM01N), digital output
module (GFDO-RM01N), power supply modules (GFPS-0202 and
GFPS-0303), and an interface module (0170-0101). The interface
module is used externally to convert KV-NC20L’s communication
module (Modbus RTU) to a RJ45 connector. The main controller
manages and dynamically configures I/O parameters. Users can choose
the model or brand of power module and interface module they
prefer.

2. KV-NC32T Connection Setup

This section explains how to connect the KV-NC32T using KV
STUDIO software. For more details, refer to the KV Nano Series
Communication Functions Manual.

2.1 KV-NC32T Hardware Connection

To connect the KV-NC32T, follow these steps:

1. The connector is at the bottom of the KV-NC20L communication
   module and uses RS485 connections.
2. Connect the COM (RS485 A/B) on the left of the FX5U to the
   interface module (1/2) to convert them to RJ45 connectors before
   connecting them to the main controller.

2.2 KV-NC32T Connection Setup

To set up the KV-NC32T connection:

1. Launch KV STUDIO and click on Unit Configuration on the left.
   Select KV-NC32.
2. Under Communication Settings, select KV-NC20L.
3. Use Port 2.
4. For Action Mode, select Modbus Master Interface: RS-485
   (2-wire) Baud: Select 115200bps Stop Bit: 1 Parity Bit: None. Note
   that the communication format setting must be consistent with the
   connected device.
5. Program your communication.

2.3 Programming Example: Control with one GFDI-RM01N and one
GFDO-RM01N

When DM0.0 receives a signal and is triggered, DM1000.0 outputs
a signal as it is connected.
