🔧 Recommended OEM Replacement Models

Original unit uses AC power; all new replacement models are DC24V, requiring an additional AC-DC power converter. Cabinet cutout sizes differ, and project migration is required.

PFXST6500TADE (ST6000 Series, 첫 번째 선택)

10.4-inch TFT color LCD; identical panel cutout size to GP2501-SC11; resolution 800×600

PFXGP4501TADW (GP4000 Series)

10.4-inch TFT screen, classic transitional replacement with mature project migration

PFXST6600WADE: 12.1-inch widescreen with different cutout size, only for cabinets with sufficient modification space

⚠️ Common Failures & Second-hand Inspection Checklist

Yellowed / black backlight: CCFL lamp aging is the most frequent fault; backlight assembly PS501S-BU00 can be replaced separately
Touch drift / partial touch failure: aging touch panel
CF card read/write error / project loss: damaged card slot or aged motherboard capacitors
No power-up response: failed rectifier capacitors on power board (common issue for AC-powered models)
Second-hand acceptance tests:

Check full-screen solid color for dead pixels and bright spots

Complete project download & upload test

Verify serial communication port

Test backlight brightness and full-area touch function

📎 Project Migration Guidelines

Legacy project: GP-PRO/PBIII project cannot be opened directly in GP4000/ST6000 programming software
Use official Pro-face migration tool to convert the project first. Color difference exists after converting STN display to TFT display; fine-tuning of screen color is required
Most PLC communication protocols can be retained, but communication parameter settings are different on new HMIs

프로페이스 GP2501-SC11 Communication Protocols

하드웨어: 내장 이더넷 포트 없음. Only one COM1 port (25-핀 D-서브, RS232C / RS422 software-selectable), asynchronous serial port only. Programming software: GP-PRO/PBIII. Only serial drivers are available, including Modbus and dedicated PLC serial protocols. Ethernet is not supported; add optional GP077-MLTE41 network card for Ethernet function.

Serial port parameters: 2400 ~ 115200 bps, 최대. 187.5 kbps; 7/8 데이터 비트, 1/2 정지 비트, none/odd/even parity

✅ Built-in Serial PLC Protocols (GP-PRO/PBIII)

Mitsubishi FX Series: Direct CPU Communication, FX Computer Link (RS422)

A 시리즈: A CPU Direct, A Computer Link

QnA Series: QnA Serial 3C/4C Frame

Siemens S5: 3964 / 3964아르 자형

S7-300/400: RK512 (3964아르 자형) (works with CP340/CP341 serial modules; native MPI is not supported)

Omron C Series Host Link

CV / CS / CJ Series Host Link

Rockwell AB SLC500 DH485 (serial driver)

Yaskawa MEMOBUS (Modbus variant over serial)

Panasonic FP Series Computer Link SIO

Keyence KZ / KV Series CPU Direct

Fuji MICREX-SX SIO

Hitachi HIDIC S10

Toshiba TC Series

Yokogawa Yokogawa PLC PC Link

✅ Standard Generic Protocols

Modbus RTU Master (오직)

RS485 bus; only RTU mode (no ASCII mode in older PBIII versions); cannot operate as Modbus Slave

This HMI only acts as Modbus master to read inverters, temperature controllers and other Modbus slave devices

✅ Temperature Controller Serial Protocols

Directly connect to RKC, Shimaden, Chino and other temperature controllers with dedicated serial drivers available in PBIII device list.

✅ Other Serial Functions

Tool port (TTL): project download, barcode scanner input; custom free serial communication via Extended SIO Script
Parallel port: Centronics printer protocol (NEC PC-PR201, Epson ESC/P, HP PCL4) for printing screens and alarm logs

⚠️ Critical Limitations

No onboard Ethernet; 모드버스 TCP / S7 TCP/IP are unavailable. Add GP077-MLTE41 expansion card for network connection.
Only one physical COM port: only one protocol can run at a time; multi-device connection is only possible via Modbus RTU multi-drop bus.
S7 MPI: native serial port cannot communicate with MPI directly; an external MPI-to-RS422 converter is required.
Custom serial communication: implement non-standard serial data exchange using PBIII Extended SIO Script.
