Product Information

Product Name: 2210TW V2.0.0 and MELSEC-Q Modbus TCP Connection

The product is a remote I/O module system that allows users to connect the MELSEC-Q series communication port (Modbus TCP) externally. It includes a gateway, main controller, digital input, digital output, and power supply modules. The main controller manages and dynamically configures I/O parameters. The power module is standard for remote I/Os and users can choose the model or brand of power module they prefer.

Remote I/O Module System Configuration List

The list includes the following:

Product Gateway Parameter Settings

This section explains how to connect the gateway to the MELSEC-Q series. For detailed information, refer to the MELSEC-Q Series Product Manual. The i-Designer program is used for setup.

i-Designer Program Setup

1. Ensure that the module is powered and connected to the gateway module using an Ethernet cable.
2. Launch the i-Designer software.
3. Select M Series Module Configuration.
4. Click on the Setting Module icon.

• Ⓕ Read Points
• Ⓖ Set to 3000h
• H The Target MODBUS Device Head Number is set to 8192
• Ⓘ Write Points

Notes

• first GFDI-RM01N has the register address at 1000(HEX) converted to 4096
• first GFDO-RM01N has the register address at 2000(HEX) converted to 8192

1. Click on “Auto_Refresh” to set up the internal register for reading and writing

Simple Program

Simple Program Demonstration using MELSEC-Q series and

• The read register address is 4096, which is D0 for the corresponding internal register of the controller.
• And the write register address is 8192, which is D300 for the corresponding internal register of the controller.
• Therefore, when you want to control the program, you can just use the internal register to control the writing and reading.
