🔄 Discontinuation & Ersatzinformationen

HMIGXU3512: No new orders accepted, spare parts maintenance phase

Offiziell empfohlener Ersatz: HMIET6400 (Harmony ET6 series 7″)

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

Upgrade auf 16 Millionen Farben, stronger hardware performance, compatible cutout dimension; configuration software changed to EcoStruxure Machine Expert HMI (formerly SoMachine HMI)

⚠️ Hinweis: 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: Überprüfen Sie die 24-V-Stromversorgung, Sicherung durchgebrannt; backlight aging (rated 20000h life)
Touch unresponsive: Beschädigtes Touchpanel, loose flat cable; corrosion in humid environment
Serial communication failure: Verify COM1/COM2 wiring, RS232/485 dip switch, Stationsnummer, baud rate and parity
Ethernet disconnection: Check network cable & schalten; HMI supports up to 48 Sklaven, do not exceed limit
Time loss: Depleted backup battery on mainboard, replace internal battery of HMI

📎 Spare Parts & Zubehör

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)

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

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

Bildschirm:7-inch wide 800×480, 16 Millionen Farben, Widerstandsberührung

Schnittstellen: 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)

Vorteile: Official designated replacement, hardware interfaces match one-to-one, Keine Schrankmodifikation erforderlich

Nachteile: 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-Zoll, 800×480, dual serial ports + Ethernet + USB, RTC, DC24V

Cutout dimension 190×135mm, mounting holes compatible, lower price than ET6400

Software: EcoStruxure Machine Expert HMI

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

Beschreibung: 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, kein 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, dual serial ports + Ethernet + USB, larger storage & bessere Leistung

Software: Vijeo-Designer (partial GXU screen migration available)

Nachteile: Much higher price, different cutout dimension, cabinet cutout modification required; 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-Zoll, dual serial ports + Ethernet, DC24V; large market inventory, user-friendly software, hohe Kostenleistung; 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-inch wide screen, dual serial ports + Ethernet, RTC; many industrial application cases in packaging & HVAC.

Pro-face PFXGP4402WADW (Schneider subsidiary brand)

7-Zoll, hohe Stabilität, widely used in high-end industrial machines; relatively high price.

📌 Selection & Replacement Comparison Table

Replacement Option	Mounting Modification	Project Reuse	Beschaffungskosten	Recommended Application
HMIET6400	Almost none	Cannot reuse, full reconfiguration	Medium	Machine retrofit, OEM spare part requirement
HMIET5400	Almost none	Cannot reuse, full reconfiguration	Niedrig	New project bulk order
HMIDT351	Cutout modification required	Partial screen migration possible	Hoch	High-end equipment, high reliability requirement
Weinview TK8072IP	Minor cutout adjustment	Full rework	Niedrig	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; Kommunikationsprotokolle (Modbus RTU/TCP) can be retained.
Verdrahtung: 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.
