Product Description:
The CX1001-0021 is an embedded PC module produced by Beckhoff within the CX Embedded PC Systems series. Acting as the central controller in compact machine or building-automation panels, it combines PLC logic and communication interfaces so that field I/O can be driven directly over the system bus without a separate industrial computer. This integration allows OEMs to install a small-footprint unit that executes deterministic control tasks alongside basic networking functions.
The processor is a Pentium MMX Compatible type that operates at 266 MHz; this clock rate defines the scan-cycle speed available for ladder or structured-text programs. Overall housing size is 57 x 100 x 91 mm, which permits DIN-rail mounting inside shallow enclosures while leaving room for adjacent terminals. For Ethernet-based supervisory links the PC exposes 1 x RJ45, and legacy devices can be polled through 1 x 9-pin D-Sub (RS232). Program execution is handled by the preinstalled TwinCAT PLC Runtime, so tasks such as PID loops or axis interpolation can be downloaded immediately after the module is powered through the 16-bit ISA (PC104) system bus. A dedicated expansion slot accepts a Compact Flash Type II card, and activity on that mass-storage channel is indicated through the front-panel diagnostic LEDs that also signal link integrity and 100 Mbit traffic.
Nonvolatile user data and boot images reside on a Compact Flash with a minimum capacity of 128 MB, allowing recipe files or small HMI pages to travel with the controller during maintenance swaps. Time-critical sequences remain synchronized even during mains outages because a Battery-Powered Internal Clock keeps absolute time for timestamping logs. Thermal loads are removed by the attachable CX1000-COOL module, enabling reliable operation in control cabinets with limited airflow.
