🔄 Discontinuation & معلومات الاستبدال

HMIGXU3512: No new orders accepted, spare parts maintenance phase

الاستبدال الموصى به رسميًا: HMIET6400 (Harmony ET6 series 7″)

Same 7-inch 800×480, dual serial ports + إيثرنت + USB, تيار مستمر 24 فولت

Upgraded to 16 مليون لون, stronger hardware performance, compatible cutout dimension; configuration software changed to EcoStruxure Machine Expert HMI (formerly SoMachine HMI)

⚠️ ملحوظة: 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: Check 24V power supply, الصمامات في مهب; backlight aging (rated 20000h life)
Touch unresponsive: Damaged touch panel, loose flat cable; corrosion in humid environment
Serial communication failure: Verify COM1/COM2 wiring, RS232/485 dip switch, station number, baud rate and parity
Ethernet disconnection: Check network cable & يُحوّل; HMI supports up to 48 slaves, do not exceed limit
Time loss: Depleted backup battery on mainboard, replace internal battery of HMI

📎 Spare Parts & مُكَمِّلات

Download cable: Mini-B USB cable

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

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

Original unit: 7″ WVGA, dual serial ports + إيثرنت + USB, RTC, تيار مستمر 24 فولت, cutout 190×135mm, Magelis GXU, Vijeo Designer Basic.

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

Screen:7-inch wide 800×480, 16 مليون لون, resistive touch

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

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

برمجة: EcoStruxure Machine Expert HMI (SoMachine HMI)

المزايا: Official designated replacement, hardware interfaces match one-to-one, no cabinet modification required

العيوب: 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-بوصة, 800×480, dual serial ports + إيثرنت + USB, RTC, تيار مستمر 24 فولت

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

برمجة: EcoStruxure Machine Expert HMI

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

وصف: 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, no 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 + إيثرنت + USB, larger storage & better performance

برمجة: Vijeo Designer (partial GXU screen migration available)

العيوب: 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-بوصة, dual serial ports + إيثرنت, تيار مستمر 24 فولت; مخزون كبير من السوق, user-friendly software, أداء عالي التكلفة; 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 + إيثرنت, RTC; many industrial application cases in packaging & التدفئة والتهوية وتكييف الهواء.

Pro-face PFXGP4402WADW (Schneider subsidiary brand)

7-بوصة, استقرار عالي, widely used in high-end industrial machines; relatively high price.

📌 Selection & Replacement Comparison Table

Replacement Option	Mounting Modification	Project Reuse	تكلفة المشتريات	Recommended Application
HMIET6400	Almost none	Cannot reuse, full reconfiguration	واسطة	Machine retrofit, OEM spare part requirement
HMIET5400	Almost none	Cannot reuse, full reconfiguration	قليل	New project bulk order
HMIDT351	Cutout modification required	Partial screen migration possible	عالي	High-end equipment, high reliability requirement
Weinview TK8072IP	Minor cutout adjustment	Full rework	قليل	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; بروتوكولات الاتصال (Modbus RTU/TCP) can be retained.
الأسلاك: COM pin assignment differs between HMIGXU3512 and replacement models. Verify serial pin definition before power-on to avoid communication port burnout.
ساعة آر تي سي: ET5/ET6 have built-in RTC, supports time retention after power loss same as original unit.
