Recommended Replacements

When a GT2710 HMI requires replacement, several options exist depending on available budget, system demands, and lifecycle goals. The table below lists the primary replacement options.

---

Compatibility Considerations

1. Panel Cutout Dimensions

All GT2710 models (regardless of -S or -V suffix, AC or DC power) share the exact same physical mounting properties:

• External Dimensions: 303 mm (W) x 218 mm (H) x 52 mm (D)
• Panel Cutout Dimensions: 289 mm (W) x 200 mm (H)

If replacing a GT2710 with another GT2710, no mechanical cutting or panel adaptation is required. If replacing an older-generation GT1675 or GT1575 (both 10.4-inch HMIs), check compatibility: they also utilize the 289 mm x 200 mm panel cutout size, making the GT2710 a mechanical drop-in replacement.

2. Resolution Variations: VGA to SVGA

If migrating from a legacy GT2710-V (640 x 480) to a GT2710-S (800 x 600), the screen resolution increases.

• Auto-scaling: When changing the HMI type in GT Designer3, the software offers automatic resolution scaling. While highly reliable, verify that text fonts, alignment, dynamic coordinate movements, and custom graphics do not overlap or distort.
• Touch Targets: Touch coordinates scale proportionally, but verification of critical pushbuttons is strongly recommended during commissioning.

3. Electrical and Power Configurations

Confirm whether the legacy unit is AC-powered or DC-powered:

• AC Series (-STBA, -VTBA): Demands 100 to 240V AC (+10% / -15%), 50/60 Hz.
• DC Series (-STBD, -VTBD): Demands 24V DC (+25% / -20%).

Warning: Connecting AC mains power to a DC unit (-STBD) will instantly destroy the device and poses severe fire/explosion hazards in industrial control panels. Always trace source lines before connecting terminals.

4. Communication Cards and Modules

The GT27 series features a rear interface expansion slot. If your old GT2710 uses an add-on communication card, such as:

• GT15-J71GP23-SX / GT25-J71GP23-SX (CC-Link IE Field Network)
• GT15-J73BUS or GT15-J73BUS2 (Bus Connection Unit)
• GT15-J61BT13 (CC-Link Communication Unit)

These cards must be powered off, carefully detached from the faulty unit, and reinstalled onto the replacement unit. Ensure slot guide pins line up perfectly before tightening the assembly screws to 0.36 to 0.48 N·m of torque.

Upgrade Benefits

Migrating to the latest GT2710 revision (such as the GT2710-STBA or GT2710-STBD) yields substantial plant floor benefits:

• Capacitive and Multi-Touch Gesture Control: Supports intuitive pinch, zoom, and swipe operations for dense schematic charts and deep-subscreen navigation. Supports two-point simultaneous touch to prevent accidental machine operation.
• VNC Remote Access: Allows engineers to remotely monitor and control the HMI via a browser, tablet, or PC, speeding up remote support diagnostics.
• Expanded Data Logging & Backup Storage: High-capacity SD cards up to 32 GB allow continuous recording of plant alarms and high-frequency variable logs.
• Enhanced Processing Architectures: Includes high-speed page-switching and low-latency communication response, minimizing time-to-first-display upon unit boot up.

Common Migration Challenges

• Font Distortion during Conversion: Standard Windows fonts and system fonts can occasionally wrap unexpectedly when converting resolution sizes (VGA to SVGA). Correct this by switching fonts to "TrueType" format in the project properties prior to rendering compilations.
• Battery Backup Errors: GT27 HMIs rely on a GT11-50BAT lithium battery to back up SRAM data (alarms, trends, recipe variables, internal clocks). When commissioning a new or refurbished HMI, verify that a fresh battery is installed and connected to the internal plug-in port beneath the rear access door.
• Communication Pinout Variations: Legacy serial configurations connecting older third-party PLCs (Modbus, Allen-Bradley DF1, Siemens PPI) may require specialized termination or distinct pin jumper profiles. Ensure that the DIP switches on the rear of the GT2710 are set correctly to matches the termination resistance of your RS-422/485 network.

Step-by-Step Replacement Procedure

Follow these manual steps to execute a safe and successful replacement.

Phase 1: Software and Program Backup

1. Open GT Designer3 (GOT2000) software on your engineering workstation.
2. Connect a Mini-USB cable from your workstation to the front and/or rear USB interface on your functional HMI (or plug an assembly Ethernet cable into the RJ-45 LAN port).
3. Select [Communication] -> [Read from GOT...].
4. Check all project folders, logging files, user-alarm histories, and recipe databases to transition from the HMI to your computer's storage directory.
5. Save this master duplicate configuration with a suffix detailing the date and source machine identity.

Phase 2: Physical Disassembly

1. Isolate Panel Power: Lock out/Tag out the main control panel power supply feeding the HMI. Verify with a calibrated digital multimeter (DMM) that 0V resides on the input terminals.
2. Disconnect Wires: Unplug the power block connector, earth grounding line, and all interfaces: Ethernet, RS-232/422 D-sub connectors, and USB options.
3. Remove Expansion Cards: Unscrew and de-allocate any communication modules fixed to the rear card interfaces.
4. Remove Panel Mounting Brackets: Using a Phillips-head driver, loosen the metal installation fixtures arrayed along the HMI’s top, bottom, and side dimensions.
5. Withdrawing the Unit: Carefully press the unit outward from the interior space of the electrical panel, supporting it from the front surface to avoid dropping.

Phase 3: Preparation and Installation

1. Clean the Panel Cutout: Wipe away oil accumulation, metal chips, and particulate debris along the panel cutout edges using a clean lint-free cloth.
2. Inspect the Gasket: Check that the rubber environmental IP67F gasket is fitted correctly into the bezel channel on the replacement GT2710. A damaged or displaced gasket will fail to seal and allow liquids to sweep into the electronics panel.
3. Mounting: Put the replacement unit through the cutout from the front of the electrical panel.
4. Insert Fixtures: Slot the mounting brackets into the matching physical slots on the HMI chassis. Tighten the mounting bracket screws using a crosswise pattern to a torque limit of 0.36 to 0.48 N·m. Avoid overtightening to prevent warping or cracking the front plastic frame.

Phase 4: Power and Communication Restoral

1. Grounding: Reconnect the functional ground wire to the designated ground lug screw terminal.
2. Apply Power Connections: Attach the operating mains inputs (100–240V AC or 24V DC depending on the unit spec sheet).
3. Restore Port Connections: Insert Ethernet, Serial, card assemblies, and system communication buses back into their marked configurations.
4. Power Up: Turn on power to the panel. Watch the initialization process to confirm the screen powers on without backlight flicker.

Phase 5: Program Transmission

1. Connect the laptop with the compiled backup file open in GT Designer3.
2. Select [Communication] -> [Write to GOT...].
3. Include physical OS/firmware dependencies if migrating software sizes or transitioning from older structures.
4. Perform the download, allowing the system to verify blocks, write files, and reset itself.
5. Test HMI screens, network communication, dynamic data links, alarm displays, and touch responses.

Frequently Asked Questions

Q1: Can I replace a GT2710-VTBD with a GT2710-STBD directly without changing any software?

No. Because the resolution alters from VGA (640x480) to SVGA (800x600), you must open the source project backup in GT Designer3, navigate to the project configuration tab, change the target model properties to the SVGA specification, scale the screens, and write the regenerated configuration to the new unit.

Q2: Is the backlight on the GT2710 series field-replaceable?

No. The high-efficiency white LED backlight is built directly into the liquid crystal module structure. If a backlight burns out or loses luminescence, the entire HMI unit must be serviced, repaired, or replaced.

Q3: What is the maximum size SD card supported by the GT2710 series?

The built-in SD card slot supports SDHC standard memory configurations up to 32 GB. Standard SD cards up to 2 GB are also fully compatible. Use FAT32 formatting.

Q4: Will my existing communication modules from an older GT16 HMI work on a GT2710?

Yes, many GT15 and GT16 communication interface adapters (such as CC-Link, MELSECNET, and Bus connection units) are physically compatible and supported by the GT27 series. Always check the specific compatibility tables in the Mitsubishi GOT2000 Series User's Manual to verify hardware versions.
