Product Introduction
The UniOP eTop310 is a 10.4-inch human-machine interface panel designed for factory and building automation applications. It features a VGA-resolution color TFT display with full vector graphics capabilities.Field experience shows this model supports over 150 communication drivers, making it highly versatile for legacy equipment. With its 64 MB internal flash memory, the unit handles complex data acquisition and multi-language runtime tasks efficiently without external storage dependencies.
Installation & Configuration Guide
Preparation (10 min)
Verify your power supply outputs exactly 24 V DC ±10%. Gather a #2 Phillips screwdriver and an ESD grounding strap. Back up any existing application files via the USB host port or Ethernet connection before removing the old panel.Removal (5–10 min)
Disconnect all field wiring from the rear terminals. Unscrew the four front mounting brackets. Push the panel gently from the rear to release the gasket seal. (Always take a photo of the terminal block wiring before disconnecting — trust me, you will forget where that yellow wire went.)Installation (10 min)
Insert the new UniOP eTop310 into the panel cutout (276 mm x 221 mm required). Secure the four mounting brackets evenly to avoid stressing the aluminum frame. Reconnect serial and Ethernet cables according to your verified pinout diagram.Power-On & Test (10 min)
Apply 24 V DC power. Observe the four system LEDs on the front bezel; they should indicate normal boot status within 15 seconds. Launch UniOP Designer 6 software to establish an Ethernet programming connection. Verify touchscreen calibration by tapping the crosshairs in all four corners.
Troubleshooting Quick Reference
- Blank Screen / No LEDs: Check 24 V DC at the rear terminal block. Measure voltage directly at the connector pins, not just at the power supply.
- Unresponsive Touch Area: Recalibrate using the system menu. If physical wear is visible, replace the resistive overlay film.
- Communication Failure: Verify baud rate and COM port settings match the PLC configuration. Swap Ethernet cables to rule out physical layer faults.
- Application Won’t Download: Ensure USB drive is formatted FAT32. Confirm firmware version matches the UniOP Designer project file revision.
- Intermittent Reboots: Measure power supply ripple. Excessive noise often causes legacy HMIs to reset unexpectedly.
Dimensions, Mounting & Wiring Notes
- Overall Dimensions: 287 mm (W) x 232 mm (H) x 42 mm (D)
- Required Cutout: 276 mm x 221 mm
- Mounting Method: Front-panel clip brackets with M4 screws
- Terminal Notes: All rear I/O uses standard industrial screw terminals. Torque to 0.5 Nm maximum to prevent stripping. PC/Printer and PLC ports are software-configurable between RS-232, RS-485, and RS-422 protocols.
FAQ
I have an old UniOP panel failing after 12 years. Is this exact model still manufactured?
No. The original UniOP line has been transitioned to EXOR’s eSMART and eX series. However, we stock New Surplus units of the eTop310 for direct replacement. Verify your application requirements with the OEM datasheet before purchasing.Will my existing UniOP Designer 5 project open in Designer 6?
Usually, yes. But always export your text strings as Unicode files first. Some macro scripts may require manual adjustment during migration. Test thoroughly on a bench setup before deploying to production.How do I know the USB port actually works?
Format a small-capacity flash drive (under 4 GB) to FAT32. Insert it while powered off, then boot the panel. The system LED should blink upon recognition. If nothing happens, check the USB cable seating.What is the lead time if your current stock runs out?
Since this is a discontinued legacy item, restocking depends entirely on secondary market availability. We recommend securing spare units immediately when replacing failed panels in critical processes.Can I use standard DIN rail power supplies for this HMI?
Yes, but ensure the supply provides at least 20% headroom above the 0.8 A maximum draw. Cheap switching supplies with poor regulation can cause erratic behavior. Stick to reputable industrial brands.Does the IP65 rating apply to the entire unit?
Only the front panel is IP65 rated. The rear electronics compartment is IP20. Never expose the rear connectors to washdown environments or high-pressure air.
