ABB PP845
Product Introduction
Walk up to a dusty packaging line or a damp pump station. You need a screen that actually survives. The ABB PP845 sits right in that sweet spot. Built on the Panel 800 architecture, this 10.1-inch TFT display handles operator inputs where standard office monitors fail instantly. Die-cast aluminum shell. Resistive touch (gloves work fine). Two Ethernet ports and multiple serial options mean it talks to legacy PLCs without needing a protocol converter.
Why keep buying these? Because replacing an entire HMI ecosystem costs thousands in re-engineering hours. This panel pulls 21.6 W and handles 85% humidity without fogging up. The .NET framework base lets it bridge multiple controller brands. Honestly, it’s an aging workhorse. Sourcing them now means paying a premium for discontinued stock, but avoiding a full system retrofit saves your maintenance budget from bleeding out.
Troubleshooting Quick Reference
- Blank Screen | No Power | 80% Probability | Check 24V DC at rear terminals | Measure voltage under load. Replace power supply if it sags below 20V.
- Touch Unresponsive | Calibration Drift | 60% Probability | Recalibrate via Panel Builder | Clean screen surface. Dirt causes phantom touches on resistive panels.
- Comm Drops | Network Flood | 40% Probability | Check Ethernet port LEDs | Isolate port. Broadcast storms from cheap switches kill old HMI NICs.
- Garbled Display | LVDS Cable | 30% Probability | Reseat internal ribbon cable | Vibration loosens connections. Check for pinched wires in the cabinet hinge.
- Won’t Boot | Corrupt Firmware | 20% Probability | Boot from USB recovery | Flash failed. Re-image using known-good USB stick. If it loops, the flash memory is dead.

Application Scenarios & Pain Points
- High-Vibration Motor Test Benches: Standard LCD brackets snap within months. The PP845’s die-cast aluminum chassis and internal potting absorb continuous 1G vibration without cracking solder joints.
- Washdown Food Processing: High-pressure caustic sprays destroy standard bezels. Front IP65 rating keeps moisture out of the touch layer, though rear IP20 means you still need a sealed cabinet.
- Brownfield Mill Retrofits: Legacy RS485 networks refuse to die. Built-in serial ports let this HMI talk to 20-year-old drives without adding expensive gateway hardware.
Compatible Replacement Models
- ✅ Drop-in Replacement: ABB PP886R / PP887H / PP887S. Same Panel 800 family. Verify physical cutout dimensions and port layout before ordering. Firmware migration usually requires a recompile in Panel Builder 800.
- ⚠️ Software Compatible: ABB CP800 Series. Same Panel Builder 800 engineering tool. Hardware mounting and port locations differ. Expect 4-8 hours of labor for mechanical adaptation and tag mapping.
- ❌ Hardware Incompatible: ABB Panel Builder 600 series (e.g., PP836). Different engineering software. Different communication protocols. Rewiring and full reprogramming required. Do not attempt as a quick swap.
