Serial transmission: via GPW-CB02 cable, with a maximum speed of 115.2kbps

Ethernet transmission: supports IP settings, remote download of screens and systems

CF card transfer: Implementing batch deployment of multiple HMIs through Memory Loader Tool

Upload: HMI → CF card (backup all data)

Download: CF Card → HMI (Recovery/Batch Deployment)

Operation mode

1. Offline mode (OFFLINE)

Entry method: Click on the top left corner within 10 seconds of startup, or enter through the menu

Core functions: initialization, self diagnosis, data transfer, memory formatting

2. Running mode (RUN)

Automatically enter upon startup, display configuration screen, and communicate in real-time with PLC

Support online modification, alarm display, data recording, and sound prompts

Initialization configuration (core item)

System environment: standby time, touch beep, password (0~9999)

I/O settings: Serial port baud rate (2400~115200bps), printer, touch calibration

PLC settings: 1:1/n:1 connection, station number (0~15), system area address, Ethernet IP

Memory initialization: password 1101, clear SRAM data, retain system and clock

Clock setting: Monthly error * * ± 65 seconds * *, lithium battery backup life of 10 years (below 40 ℃)

Self diagnostic function

Covering full hardware detection and quickly locating faults:

Character/display pattern, touch screen, internal Flash, frame buffer

Serial port, printer, CF card, sound, extended serial port

Each test returns OK/NG to guide maintenance

Troubleshooting (high-frequency issues)

Common causes and solutions of fault phenomena

No display power error, backlight burned out, screen turned off. Check power supply, replace backlight, clear system area shutdown command

PLC communication line sequence error, baud rate mismatch, station number conflict rewiring, calibration parameters, unique station number

Touch failure, backlight failure, disabling, calibration error, peripheral interference, backlight replacement, recalibration, disconnection of peripheral devices

The startup beep system program is damaged, the CF card boot file is lost, and the system is forcibly downloaded. The CF card file is repaired

Maintenance and upkeep

Cleaning: Neutral detergent, no organic solvents, sharp objects

Sealing gasket: replaced annually to ensure IP65f protection

Backlight replacement: lifespan of 50000 hours, power-off operation, model matching

Battery: cannot be replaced by oneself, replaced by the agent to prevent explosion

Key issues

Question 1: How can GP series HMI achieve batch deployment of multiple devices through CF cards?

Answer: First, complete the configuration and settings on an HMI, and upload the complete system, screen, protocol, and data to the CF card through the offline mode CF Memory Loader Tool; Insert the CF card into another HMI, toggle DIP switch 1 or start it through the CF BOOT menu, and download to batch copy without connecting to each computer.

Question 2: What is the most likely reason and troubleshooting steps for the touch screen not responding but the screen is on?

Answer: The most likely reason is that the backlight burns out and triggers safety protection, which is automatically disabled by touch. Troubleshooting steps: ① Check if the status light is orange → If it is, there is a backlight fault; ② Enter offline mode to test touch → normal is the protection mechanism; ③ Enable temporary recovery of USE TOUCH PANEL AFTER BACK LIGHT BURNOUT during initialization, and replace the backlight as soon as possible.

Question 3: What order should be followed to troubleshoot the PLC communication error "PLC NOT Replying"?

Answer: Check in order from hardware to parameters: ① Check that the PLC power is turned on; ② Confirm that the RS-232C/422 cable is wired correctly; ③ Verify that the baud rate, data bits, checksum, and stop bits of HMI and PLC are completely consistent; ④ Check that the 1:1/n:1 mode, station number, and system area address are set correctly; ⑤ Start the PLC first and delay for 2-3 seconds before starting the HMI to ensure the correct startup sequence.
