Description
Designed to execute localized control, visualization, and monitoring tasks within demanding automated systems, the Beckhoff CP6231-0002-0070 integrates a 12-inch TFT display with a high-performance industrial PC core. This economy built-in Panel PC features a mechanical configuration with an aluminum front bezel and a robust sheet-steel rear cover, designed specifically for control cabinet installation. Equipped with an Intel Celeron G3900TE processor operating at 2.3 GHz and 4 GB of DDR4 RAM, the device provides reliable processing power for PLC, motion control, and HMI runtimes. It operates efficiently in environments ranging from 0 to 55 degC, delivering high physical durability and stable execution under constant industrial workloads.

Alternative Models & Compatibility
The Beckhoff CP6231 series maintains high physical mounting backwards-compatibility with previous generations of CP62xx built-in panel hardware. When upgrading from older platforms utilizing Intel Atom or Celeron processors of lower processing categories, confirm the physical control cabinet cutout dimensions match the standard 12-inch configuration. This unit is optimized for modern configurations; target licensing classes for TwinCAT runtime applications default to TwinCAT 3 performance class 50 (TC3: 50) due to the Celeron G3900TE core architecture.
Application Pitfalls & Engineering Notes
Operating this built-in Panel PC requires strict adherence to natural convection paths. Ensure the panel is mounted vertically within the cabinet cutout. Obstructing the integrated ventilation slots on the sheet-steel rear cover can result in localized hot spots, prompting the onboard thermal management system to throttle CPU clock speeds. For systems subjected to high vibratory profiles, use a solid-state CFast card or standard industrial SSD rather than a physical spinning hard disk to prevent drive-head write errors and subsequent file corruption.
Commissioning & Wiring Tips
During the commissioning stage, establish a low-impedance connection from the functional ground terminal block to the central machine ground. This grounding is critical to shunt electromagnetic noise, ensuring consistent touch-screen detection without erratic signal jumps. If integrating network redundancy or separate operational technology (OT) zones, the dual onboard RJ45 Gigabit Ethernet ports are mapped to separate independent network controllers and should be assigned static IP configurations on separate subnets to avoid route loop-backs.
Installation Guidelines
CRITICAL WARNING: ELECTRICAL SHOCK AND COMPONENT DAMAGE RISKS
Always isolate and de-energize the complete cabinet and associated 24 V DC supply conductors before preparing the mounting cutout or making field wire connections. Failure to fully remove power can result in system motherboard failures, internal voltage-rail damage, or severe electric shock hazards for operational personnel.
1
Ensure the installation cabinet cutout is prepared precisely to the standard 12-inch dimensions. Deburr all raw metal edges and clear debris.
2
Examine the circumferential flat gasket integrated on the front bezel of the Panel PC for correct seating and integrity.
3
Push the hardware unit into the prepared cutout from the front of the cabinet door.
4
Secure the unit internally by tightening the integrated pull-out clamping levers against the cabinet panel thickness. Do not over-torque.
5
Connect the functional ground wire, plug in all necessary peripheral cables (Ethernet, USB, DVI), and lock the 24 V DC input connector block.
