Product Description:
The CX2040-0135 is an embedded PC manufactured by Beckhoff and assigned to the CX Embedded PC Systems series. It serves as a compact control platform that combines Windows-based computing with PLC tasks for motion, logic, and HMI duties on the factory floor. An Intel Core i7-2715QE quad-core CPU running at 2.1 GHz supplies deterministic processing power for automation sequences, fieldbus handling, and user interfaces. This arrangement allows one compact unit to manage machine control, communication, and local visualization without requiring a separate industrial computer.
The controller carries 4 GB DDR3-RAM, allowing simultaneous execution of real-time tasks and supervisory software without paging delays. Integrated graphics run at a base clock of 650 MHz and can accelerate up to 1.2 GHz, supporting local display panels through the Intel HD Graphics 3000 engine. Heat produced by the CPU, chipset, and shared graphics memory is kept low enough that total power draw does not exceed 32 W, which simplifies cabinet cooling. The housing measures 144 × 99 × 91 mm, and two RJ45 Gigabit Ethernet ports support separate machine and enterprise networks. The hardware also accepts expansion modules on its side bus for additional fieldbus masters or serial interfaces without changing the main enclosure.
The unit operates from a single 24 V DC supply line and includes a CFast slot with at least 40 GB of solid-state storage for the operating system, TwinCAT projects, and historical data. For nonvolatile variable retention, the system integrates 128 kB of Novram, preserving counters and recipes during power loss. The front panel has 4 × USB 2.0 sockets, each able to deliver up to 500 mA for service tools, radio adapters, or removable backups. The controller runs TwinCAT 3 XAR to execute IEC 61131-3 code with cycle times down to the sub-millisecond range. Additional connectivity includes two LAN LEDs per port for link diagnostics, and the shared-memory graphics architecture leaves more DRAM available for user programs.
