Product Introduction
The ABB / Genera Oy GOP2 G2010 A 10.4ST is a heavy-duty Graphic Operator Panel (GOP) designed for local process automation, drive control, and demanding marine vessel management systems. Engineered in Finland, this 10.4-inch terminal serves as the direct link between human operators and specialized industrial systems (such as high-voltage drives, thruster systems, or marine generator control schemes). The panel coordinates process parameters using ABB’s legacy Panel Builder programming environment, providing clear graphical screens, live trend tracking, and custom-mapped pushbuttons.
The G2010 A 10.4ST features a wider input voltage range (24V–48V DC) than standard commercial panels, making it highly resilient to voltage fluctuations common in maritime electrical grids and remote generator substations. Because ABB officially transitioned the GOP2 series into its final Obsolete Phase on January 1, 2025, direct factory distribution has ceased. Securing reliable, fully tested surplus units or component spares (like replacement touch digitizers and keypad membranes) is essential for maintaining legacy systems and avoiding costly system overhauls.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
| The screen is completely dark, but the system is running | Blown internal DC-DC fuse or failed CCFL backlight inverter | ✅ High | Check if the 24V–48V DC supply is present at the input terminal. Shine a flashlight at an angle onto the LCD to see if faint icons are visible under the glass. | If faint graphics are visible, the backlight inverter or lamps have failed. Replace the display component or swap the complete G2010 unit. |
| The panel powers up but fails to respond to touch input | Cracks, wear, or misalignment on the resistive touch sheet | ✅ High | Inspect the outer glass layer for deep scratches, deep localized indents, or bubbling. Run the built-in screen calibration routine. | If the screen cannot register coordinate tracking or calibration fails, replace the outer touch screen digitizer glass. |
| Specific physical keypad buttons do not trigger actions | Worn dome switches or fractured ribbon traces inside the membrane layer | ✅ High | Gently press the affected button and check for a physical click. Use system diagnostics to see if the corresponding PLC input bit registers. | The front keypad membrane has degraded. Install a new replacement membrane overlay sheet (such as B394073). |
| “Communication Failure” or offline alarms on the HMI display | Faulty serial/Ethernet connection or network address mismatch | ✅ Medium | Check the status of the communication cable at the back of the terminal. Verify the configured IP/MAC addresses match the network layout. | Ensure the cable is secure. If the physical ports are damaged or communication transceivers have failed, swap the panel’s interface board. |
Frequently Asked Questions (FAQ)
Can the GOP2 G2010 A 10.4ST be configured using modern ABB Panel Builder software?
The A 10.4ST relies on older, legacy versions of the ABB Panel Builder suite designed to support GOP2 and GOP3 system hardware profiles. Modern Panel Builder platforms (such as Panel Builder 600) are built for current CP600 series touch panels and do not natively support database transfers to these legacy units. Always preserve your original .cb or application source files to ensure you can load configurations onto replacement panels.
Is it possible to replace only the touch glass or keyboard membrane instead of buying a whole new panel?
Yes. Because these units are obsolete and expensive to source as complete assemblies, component-level repair is highly common. Replacement parts—including the adhesive-backed B394073 keypad membrane and the 10.4-inch analog-resistive touch screen glass—are readily available as replacement parts to restore damaged interfaces.
What does the 1.0X revision marking mean on the backplate?
The revision number (such as Ver: 1.0X) indicates the specific hardware and firmware revision shipped from the factory in Finland. While most A 10.4ST panels remain backward compatible, some highly customized setups in marine navigation or heavy machinery require matching firmware versions to prevent network errors. Always check the revision tag on your current unit when planning a swap.
What are my migration options now that the GOP2/GOP3 series is fully obsolete?
Since January 1, 2025, ABB has placed this series into the Obsolete Phase, meaning technical support and factory repairs are no longer provided. For long-term reliability, ABB recommends migrating your HMI configurations to modern equivalents, such as the CP600 or CP600-Pro series. If immediate system migration is not feasible due to physical space constraints or software complexities, stocking certified surplus spares is the best strategy.
How do you verify the quality of your surplus or refurbished A 10.4ST panels?
Every unit in our inventory undergoes extensive testing before shipment. We verify the power input stage across its full voltage range, run diagnostic display test patterns to check for dead pixels or failing backlights, and perform full touch grid calibration. All units are shipped securely in anti-static packaging and are backed by our 1-year replacement warranty.
