Operation mode (offline/running)

Off line Mode

Enter: Press the top left corner within 10 seconds of booting, or force reset

Menu: initialization, screen transfer, self diagnosis, operation

RUN Mode

Automatically enter upon startup and communicate in real-time with the PLC

Press the top left corner within 10 seconds to switch back offline

Initialization Settings (Core)

System environment: standby time, buzzer, password (0-9999)

Serial port settings: baud rate, data bits, parity, communication format

PLC settings

1: 1: Starting address and unit number of the system area

n: 1: Station number (0-15, cannot be repeated), network address

Other: Memory initialization, time and date, boot screen, font

Self diagnostic function

The testing items include:

Display screen, touch panel, internal storage, serial port, tool port

The result shows OK/NG, assisting in quickly locating hardware faults

Fault and error handling

Typical faults

No display: Check power supply, cables, backlight

Not communicating: protocol, baud rate, wiring, terminal resistance

Touch invalid: calibration, settings, hardware failure

Common error codes

Cleaning: Neutral cleaner, no organic solvents allowed

Regular inspection: temperature, humidity, voltage, wiring, sealing gasket

Backlight replacement: Model GP370-BL00-MS, operate with gloves when powered off

Clock battery: cannot be replaced by oneself, contact the agent

Key issues

Question 1: What are the two methods for GP-370 to enter offline mode? What is the function of a password?

answer:

Method 1: Touch the top left corner of the screen within 10 seconds of starting up;

Method 2: Force reset and press OFFLINE.

Password (0-9999) is used to protect initialization settings and prevent accidental modification of parameters and memory initialization.

Question 2: What is the difference between the 1:1 and n:1 communication methods of GP-370? What are the requirements for setting station numbers?

answer:

1: 1:1 HMI directly connected to 1 PLC, with simple configuration;

n: 1: Multiple HMIs share one PLC and communicate through tokens.

The station number must be between 0-15 and cannot be duplicated within the same network, otherwise a duplicate station number error will be reported.

Question 3: What process should be followed to troubleshoot the GP-370 no display fault?

answer:

Check if the DC24V power supply is normal;

Confirm if the power light is on and if the cable is properly connected;

Check if the screen data has been downloaded;

Enter offline mode to see if it is displayed and determine whether it is a screen or system issue;

Check if the backlight is damaged and replace it if necessary.
