Product Overview

The Schneider Electric HMIGTO2300 is a 5.7-inch operator terminal in the Harmony GTO series, intended for machine control panels where operators need a clear view of equipment status, process values, and operating commands. Its color TFT touchscreen uses a 320 × 240 pixel QVGA resolution, making it suitable for compact HMI screens that combine numerical readings, alarm messages, status indicators, and basic process graphics.

Unlike the HMIGTO2310, the HMIGTO2300 does not include an Ethernet port. Its communication interfaces consist of an RS-232C COM1 port and an RS-485 COM2 port. This configuration suits equipment that exchanges data with a PLC or other controller over supported serial protocols. When planning a replacement, engineers should check the original communication method rather than assuming that the HMIGTO2300 can directly replace an Ethernet-connected terminal.

On a packaging machine, the HMIGTO2300 can display production counts, machine operating modes, fault messages, and adjustable process parameters. An operator can select a screen, review a fault condition, or change a permitted setting through the resistive touchscreen. The application project determines which controls are available and which values can be modified.

The terminal runs a Harmony HMI environment and supports Vijeo Designer for application configuration. Its 64 MB application Flash memory and battery-backed SRAM support the specified operating configuration. USB Type-A and Mini-B interfaces provide additional connectivity for compatible peripheral and service functions.

For an existing installation, the most important checks are the HMI project version, PLC driver, serial cable wiring, communication parameters, panel cutout, and power supply. The HMIGTO2300 is particularly appropriate when the existing machine uses serial communication and the 5.7-inch display format meets the operator’s requirements.

Technical Specifications

Product Features

• 5.7-inch color display: Provides more screen area than the 3.5-inch HMIGTO1300 and HMIGTO1310 terminals for displaying operating values and machine status.
• QVGA graphics: Displays numerical data, alarms, indicators, and configured process screens at 320 × 240 resolution.
• Resistive touchscreen: Supports direct interaction with application-defined controls.
• Dual serial interfaces: Uses RS-232C and RS-485 connections for compatible PLCs and industrial equipment.
• 64 MB application memory: Supports the terminal’s configured HMI application.
• Vijeo Designer compatibility: Allows engineers to configure screens, data objects, alarms, and controller communication.
• USB connectivity: Includes Type-A and Mini-B interfaces for supported peripheral and service functions.
• Industrial front-panel protection: Provides IP65 and NEMA 4X indoor-use protection when installed under the specified conditions.
• Natural air circulation: Avoids the need for a forced-air cooling fan within the terminal.

Working Principle

The HMIGTO2300 serves as the operator interface for a PLC-controlled machine. Its internal processing environment executes the configured HMI project, while the touchscreen displays process information and accepts operator input.

A typical communication path is:

PLC or Machine Controller → RS-232C / RS-485 → HMIGTO2300 → Touchscreen → Operator

During operation, the HMI application exchanges data with the connected controller through the configured communication driver. The terminal displays information such as operating status, production totals, process values, and alarms. When an operator touches a screen object, the application processes the input and sends the associated request to the controller.

COM1 uses RS-232C through a 9-pin D-Sub connector, while COM2 uses RS-485 through an RJ45 connector. These interfaces have different electrical and wiring requirements. The correct port must be selected for the connected equipment, and the communication protocol, addressing, and serial parameters must match the controller configuration.

The HMIGTO2300 does not have an Ethernet interface. Therefore, a system that depends on direct Ethernet communication cannot use this terminal as a direct replacement without changing the communication arrangement or selecting a different model.

Vijeo Designer defines the application behavior, including screen navigation, displayed values, alarm messages, and operator commands. The PLC remains responsible for executing the machine’s control logic, interlocks, and physical outputs. The HMI provides the local interface through which operators monitor the process and submit permitted commands.

Role in an Industrial HMI Architecture

The HMIGTO2300 occupies the local operator-interface layer of an automation system. It presents controller data on the touchscreen and passes operator requests through the configured serial communication channel.

PLC / Machine Controller → Serial Communication → HMIGTO2300 → Operator

Industrial Applications

Installation and Maintenance

1. Verify the model: Confirm that HMIGTO2300 is suitable for the application, particularly where the existing system uses serial communication rather than Ethernet.
2. Check the panel cutout: Verify the mounting opening against the terminal’s installation requirements before preparing the cabinet.
3. Confirm the DC supply: Use a compatible 24 V DC supply within the specified 19.2–28.8 V range.
4. Inspect the mounting seal: Keep the mounting surface clean and verify the gasket arrangement to maintain the specified front-panel protection.
5. Identify the serial ports: Confirm whether the PLC connects through COM1 RS-232C or COM2 RS-485.
6. Verify cable wiring: Match connector pin assignments, electrical standards, shielding, and cable type to the connected equipment.
7. Configure communication parameters: Check the protocol, addressing, baud rate, parity, and other settings required by the PLC driver.
8. Review the HMI project: Confirm the Vijeo Designer project version, target terminal, screen configuration, and controller driver before transferring the application.
9. Inspect USB connections: Verify that connected peripherals are supported and used for their intended service or data-transfer functions.
10. Test screen navigation: Confirm that touchscreen selections, numerical entry, and configured controls respond as expected.
11. Validate PLC communication: Check process-value updates, alarm reporting, and permitted commands before returning the machine to operation.
12. Document the installation: Record the HMI model, project version, serial settings, cable assignments, and commissioning results for future maintenance.

Technical FAQs

Does the HMIGTO2300 have an Ethernet port?

No. The HMIGTO2300 provides RS-232C through COM1 and RS-485 through COM2, but it does not include Ethernet. For applications requiring a direct Ethernet connection, the HMIGTO2310 is a related model to evaluate.

Can the HMIGTO2300 communicate with different PLC brands?

It can communicate with compatible controllers when the appropriate protocol and device driver are supported by the HMI application. Before selecting a controller, check the available Vijeo Designer driver, the PLC’s communication interface, and the required serial settings.

What should be verified before replacing an HMIGTO2300?

Check the HMI project, controller driver, serial port assignment, wiring, supply voltage, and panel cutout. After installation, test screen operation, process-value updates, alarm display, and controller communication before returning the machine to normal service.

Is the HMIGTO2300 suitable for displaying detailed process diagrams?

It can display configured diagrams, status indicators, alarms, and process values at 320 × 240 resolution. For applications that require many simultaneous values or more detailed graphical layouts, a larger Harmony GTO terminal may provide a more practical viewing area.
