Product Overview

The Schneider Electric HMIGK5310 is a Harmony GK operator terminal that combines a 10.4-inch color touchscreen with a physical keypad. Unlike touchscreen-only HMIs, this model gives operators two ways to interact with a machine: selecting graphical controls on the display and entering commands or numeric values through dedicated keys. This arrangement is particularly useful in industrial environments where operators regularly enter setpoints, acknowledge alarms, change operating modes, or work with the panel while wearing protective gloves.

The terminal uses a VGA TFT LCD with a resolution of 640 × 480 pixels and supports 65,536 display colors. Its interface can present process diagrams, operating parameters, text messages, alarm information, and graphical controls configured in the HMI application. Eighteen dynamic function keys with LEDs can be assigned to application-specific operations, while 12 static function keys provide consistent access to frequently used functions. The additional alphanumeric keypad and service keys support data entry and navigation.

In a packaging machine, for example, an operator may use the touchscreen to review the production sequence and select a recipe, then use the keypad to enter a target value or confirm an adjustment. On a CNC-related auxiliary machine, the terminal can display equipment status, process information, and operator instructions while providing physical keys for repetitive commands. The actual functions available depend on the application project and the connected controller.

The HMIGK5310 operates from a nominal 24 V DC supply and supports Ethernet TCP/IP, RS-232C, and RS-485 communication. These interfaces allow the terminal to exchange data with compatible PLCs and other automation equipment. An SD card slot and USB connections support applicable storage and service operations, while its front-panel protection makes it suitable for installations where the operator interface is exposed to dust, splashing water, or routine industrial cleaning conditions within the specified limits.

When replacing an existing terminal, the main considerations are the HMI project, communication protocol, controller interface, panel cutout, and physical key assignments. Retaining the same model can simplify the process of matching the original operator layout, but the project and communication configuration should still be checked before the replacement is commissioned.

Working Principle

The HMIGK5310 functions as the operator interface between personnel and a connected automation controller. Its internal processor executes the configured Harmony HMI application, while the display and physical keys provide the means to view machine information and enter commands.

A typical operating sequence follows this arrangement:

PLC or Controller → Ethernet / Serial Communication → HMIGK5310 → Touchscreen and Keypad → Operator

During operation, the terminal requests or receives process data through the communication driver configured in the HMI project. The application converts this information into numerical readings, status indicators, graphical process representations, and alarm messages. When an operator touches a screen control or presses an assigned function key, the application processes the input and communicates the corresponding request to the controller.

The keypad is particularly useful for applications requiring repeated numeric entry. An operator may enter a temperature setpoint, production quantity, timer value, or machine parameter using the alphanumeric keys, then confirm the entry with the appropriate service key. Dynamic function keys can be configured according to the current screen, allowing the same physical keys to perform different functions in different operating contexts.

The Ethernet interface supports network communication with compatible controllers, while the serial interfaces accommodate devices using RS-232C or RS-485. The selected protocol, port, wiring, and communication parameters must match the connected equipment. A physically connected cable alone does not establish successful communication; the controller address, serial settings, and application driver must also be correct.

Vijeo Designer is used to configure the terminal’s application screens, graphical objects, data displays, and operator controls. The application project determines which values can be viewed, which keys are assigned to specific actions, and what permissions or operating conditions apply to a command.

The HMIGK5310 does not independently execute the machine’s control sequence. The PLC or other connected controller remains responsible for its configured control logic, interlocks, and machine outputs. The terminal provides the interface through which operators supervise the process and submit permitted commands.

Role in an Industrial HMI Architecture

The HMIGK5310 occupies the operator-interface layer of a machine control system. It presents controller data in a form that operators can interpret and provides touchscreen and keypad inputs for permitted operating functions.

Industrial Applications

Installation and Maintenance

1. Verify the model number: Confirm that HMIGK5310 matches the intended replacement and that the existing application requires a keypad-and-touchscreen terminal.
2. Check the panel cutout: Verify the mounting opening and clearance against the specified installation drawings before fitting the terminal into the cabinet.
3. Confirm the DC supply: Ensure that the supply voltage remains within 19.2–28.8 V DC and that the wiring follows the applicable electrical installation requirements.
4. Inspect the mounting hardware: Secure the terminal using the specified mounting arrangement and ensure that the front gasket seats correctly against the panel.
5. Protect the front-panel seal: Check the sealing surface for contamination or damage, particularly where the installation relies on IP65 front protection.
6. Verify Ethernet wiring: Confirm the correct network connection, cable condition, IP configuration, and communication settings for the connected controller.
7. Check serial connections: Identify whether the application uses RS-232C or RS-485 and verify the corresponding wiring and communication parameters.
8. Review keypad assignments: Confirm that static keys, dynamic function keys, and service-key operations correspond to the intended application screens and machine functions.
9. Check the HMI project: Verify the Vijeo Designer project, controller drivers, screen configuration, and application version before loading or restoring the project.
10. Test operator input: Confirm that touchscreen selections and keypad entries are registered correctly and that the application applies the intended validation rules.
11. Validate controller communication: Check displayed process values, alarm updates, and permitted commands before returning the machine to normal operation.
12. Record commissioning results: Document the terminal model, project version, communication parameters, key assignments, and functional test results for future maintenance.

Technical FAQs

When is a keypad-and-touchscreen HMI preferable to a touchscreen-only terminal?

It is useful when operators frequently enter numeric values, use repeated commands, or need physical keys for predictable navigation. The HMIGK5310 combines a graphical interface with dedicated function and alphanumeric keys, allowing the application to assign the most appropriate input method to each task.

How should the HMIGK5310 be connected to a PLC?

The connection depends on the PLC’s available interface and the communication driver configured in Vijeo Designer. Ethernet TCP/IP can be used with compatible networked controllers, while RS-232C or RS-485 may be appropriate for supported serial connections. The selected interface, wiring, protocol, and communication parameters must match the controller.

What should be checked when replacing an HMIGK5310?

Confirm the panel cutout, supply voltage, communication connections, HMI project version, and function-key assignments. Back up the original application and configuration where possible, then test the screen controls, keypad input, alarm display, and controller communication before returning the equipment to service.

Does the HMIGK5310’s IP65 rating apply to the entire terminal?

No. The IP65 rating applies to the front panel under the specified installation conditions. The rear panel is rated IP20, so the cabinet and installation arrangement must provide appropriate protection for the rear of the terminal.
