🔄 Discontinuation & Informações de substituição

HMIGXU3512: No new orders accepted, spare parts maintenance phase

Substituição oficial recomendada: HMIET6400 (Harmony ET6 series 7″)

Same 7-inch 800×480, portas seriais duplas + Ethernet + USB, CC24V

Atualizado para 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

Black screen at power-on: Verifique a fonte de alimentação de 24V, fusível queimado; backlight aging (rated 20000h life)
Touch unresponsive: Painel de toque danificado, loose flat cable; corrosion in humid environment
Falha na comunicação serial: Verify COM1/COM2 wiring, RS232/485 dip switch, station number, baud rate and parity
Ethernet disconnection: Check network cable & trocar; HMI supports up to 48 escravos, do not exceed limit
Time loss: Depleted backup battery on mainboard, replace internal battery of HMI

📎 Spare Parts & Acessórios

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)

Unidade original: 7″ WVGA, portas seriais duplas + Ethernet + USB, RTC, CC24V, cutout 190×135mm, Magelis GXU, Vijeo Designer Basic.

Schneider OEM Alternatives (Recomendado, consistent brand & stable spare parts supply)
HMIET6400【Official Direct Replacement】

Tela:7-inch wide 800×480, 16 million colors, resistive touch

Interfaces: 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

Programas: EcoStruxure Machine Expert HMI (SoMachine HMI)

Vantagens: Official designated replacement, hardware interfaces match one-to-one, nenhuma modificação do gabinete necessária

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

HMIET5400【Economical OEM alternative, preferred for new projects】

7-polegada, 800×480, portas seriais duplas + Ethernet + USB, RTC, CC24V

Cutout dimension 190×135mm, furos de montagem compatíveis, lower price than ET6400

Programas: EcoStruxure Machine Expert HMI

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

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

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

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

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

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

7-inch WVGA, portas seriais duplas + Ethernet + USB, larger storage & melhor desempenho

Programas: Vijeo Designer (partial GXU screen migration available)

Desvantagens: Much higher price, different cutout dimension, modificação do recorte do gabinete necessária; for high-reliability machinery.

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.

Weinview TK8072IP / MT8072IP

7-polegada, portas seriais duplas + Ethernet, CC24V; grande estoque de mercado, user-friendly software, desempenho de alto custo; similar cutout, minor cabinet modification.

MCGS TPC7022Ni

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

FLEXEM FE6070W

7-tela larga de polegadas, portas seriais duplas + Ethernet, RTC; many industrial application cases in packaging & AVAC.

Pro-face PFXGP4402WADW (Schneider subsidiary brand)

7-polegada, alta estabilidade, widely used in high-end industrial machines; relatively high price.

📌 Selection & Replacement Comparison Table

Opção de substituição	Mounting Modification	Project Reuse	Custo de aquisição	Aplicação recomendada
HMIET6400	Almost none	Cannot reuse, full reconfiguration	Médio	Machine retrofit, OEM spare part requirement
HMIET5400	Almost none	Cannot reuse, full reconfiguration	Baixo	New project bulk order
HMIDT351	Cutout modification required	Partial screen migration possible	Alto	High-end equipment, high reliability requirement
Weinview TK8072IP	Minor cutout adjustment	Full rework	Baixo	Cost-down retrofit, brand unrestricted

⚠️ Important Notes for Replacement

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