🔄 Discontinuation & Informazioni sulla sostituzione

HMIGXU3512: No new orders accepted, spare parts maintenance phase

Sostituzione consigliata ufficialmente: HMIET6400 (Harmony ET6 series 7″)

Same 7-inch 800×480, dual serial ports + Ethernet + USB, DC24V

Aggiornato a 16 million colors, stronger hardware performance, compatible cutout dimension; configuration software changed to EcoStruxure Machine Expert HMI (formerly SoMachine HMI)

⚠️ Nota: GXU project files cannot be imported directly into ET6. Screens need re-configuration, most communication protocols remain available.

🧰 Troubleshooting for HMIGXU3512 Common Faults

1. Black screen at power-on: Check 24V power supply, blown fuse; backlight aging (rated 20000h life)
2. Touch unresponsive: Damaged touch panel, loose flat cable; corrosion in humid environment
3. Errore di comunicazione seriale: Verify COM1/COM2 wiring, RS232/485 dip switch, station number, baud rate and parity
4. Ethernet disconnection: Check network cable & interruttore; HMI supports up to 48 schiavi, do not exceed limit
5. Time loss: Depleted backup battery on mainboard, replace internal battery of HMI

📎 Spare Parts & Accessori

Download cable: Mini-B USB cable

Serial communication cable: DB9 serial cable (RS485/232)

Replacement parts: touch panel, backlight module, power board (repair components)

HMIGXU3512 Alternative Models (Schneider OEM alternatives + 3rd-party compatible models)

Original unit: 7″ WVGA, dual serial ports + Ethernet + USB, RTC, DC24V, cutout 190×135mm, Magelis GXU, Vijeo Designer Basic.

1. Schneider OEM Alternatives (Raccomandato, consistent brand & stable spare parts supply)
2. HMIET6400【Official Direct Replacement】

Schermo:7-inch wide 800×480, 16 million colors, tocco resistivo

Interfacce: COM1/COM2 (RS232/485/422), 10/100 Ethernet, USB Host+Device, built-in RTC

Power DC24V, fully compatible cutout size 190×135mm, front panel IP65

Software: EcoStruxure Machine Expert HMI (SoMachine HMI)

Vantaggi: Official designated replacement, hardware interfaces match one-to-one, nessuna modifica del mobile richiesta

Svantaggi: GXU project cannot be imported directly, re-design screens required; download port changed to Micro USB instead of Mini-B

2. HMIET5400【Economical OEM alternative, preferred for new projects】

7-pollice, 800×480, dual serial ports + Ethernet + USB, RTC, DC24V

Cutout dimension 190×135mm, fori di montaggio compatibili, lower price than ET6400

Software: EcoStruxure Machine Expert HMI

Applicazione: Bulk new project procurement, renovation projects with limited budget

Descrizione: ET5 series is Schneider’s new entry HMI, long-term main replacement product for GXU.

3. HMIGXU3500 (Same-series old stock spare part, NOT recommended for new projects)

Same GXU series 7-inch HMI, niente Ethernet, no RTC

Only for equipment using serial communication only, no Ethernet or time function; discontinued spare with unstable stock, only emergency replacement.

4. Upgrade option: HMIDT351 (Magelis GTU, mid-range higher performance)

7-inch WVGA, dual serial ports + Ethernet + USB, larger storage & prestazioni migliori

Software: Vijeo Designer (partial GXU screen migration available)

Svantaggi: Much higher price, different cutout dimension, cabinet cutout modification required; for high-reliability machinery.

1. 3rd-party Compatible Alternatives (Retain original PLC communication, brand change for cost-down retrofit)

All support Modbus RTU/TCP to connect Schneider M218/M241/M251 PLCs, screen projects need full rework.

1. Weinview TK8072IP / MT8072IP

7-pollice, dual serial ports + Ethernet, DC24V; ampio inventario di mercato, user-friendly software, prestazione ad alto costo; similar cutout, minor cabinet modification.

2. MCGS TPC7022Ni

Mainstream domestic HMI, MCGS configuration software, mature Modbus communication; widely used in domestic machinery, convenient local after-sales service.

3. FLEXEM FE6070W

7-schermo largo pollici, dual serial ports + Ethernet, RTC; many industrial application cases in packaging & HVAC.

4. Pro-face PFXGP4402WADW (Schneider subsidiary brand)

7-pollice, elevata stabilità, widely used in high-end industrial machines; relatively high price.

📌 Selection & Replacement Comparison Table

⚠️ Important Notes for Replacement

1. Compatible cutout ≠ compatible project: GXU (Vijeo Designer Basic) project files cannot be imported to ET5/ET6. Screens, tags and alarms must be rebuilt; protocolli di comunicazione (ModBus RTU/TCP) can be retained.
2. Cablaggio: COM pin assignment differs between HMIGXU3512 and replacement models. Verify serial pin definition before power-on to avoid communication port burnout.
3. Orologio RTC: ET5/ET6 have built-in RTC, supports time retention after power loss same as original unit.
