Product Description:
The CX1020-0021 is an embedded PC controller produced by Beckhoff and belongs to the CX Embedded PC Systems series. Mounted directly in the control cabinet, it serves as the central processing element for PLC tasks, motion sequences, and fieldbus routing within automated machinery. By integrating PC technology and industrial I/O on a compact footprint, the device allows OEMs to replace traditional rack PCs and separate PLC hardware with one unified platform.
Beneath the housing, an Intel Celeron M ULV processor executes control code at 1 GHz, giving deterministic cycle times for medium-sized applications. The unit ships with Windows XP Embedded, so standard PC software tools and Beckhoff TwinCAT can coexist on the same runtime. Two onboard Ethernet controllers present as 2 x RJ45 sockets; together with the integrated 3-port switch, they support line topology without external hubs. During full CPU load and fieldbus traffic the device dissipates only 11 W of power, which simplifies cabinet ventilation and permits operation from limited 24 V DC supplies. A battery-backed real-time clock maintains system time during outages for accurate data stamping.
The CompactFlash interface accepts Type I+II cards for program and data storage, avoiding rotating media. Heat is removed solely through passive cooling fins, so no fans draw dust into the enclosure. Five diagnostic LEDs on the front report CPU status, bus activity, and flash access at a glance. With overall dimensions of 96 × 112 × 99 mm, the PC fits beside standard terminal modules and maintains the series’ uniform depth. The internal switch has a 3-port design, and the controller uses a 16-bit ISA PC/104 system bus internally. The protection class is IP20, and the TwinCAT PLC runtime runs automatically after boot, even though no DVI or USB connectors are provided.
