The BECKHOFF CX9020-N031 is a compact, DIN-rail-mountable Embedded PC designed for mid-range PLC and Motion Control applications. Powered by an ARM Cortex-A8 processor, this basic CPU module integrates a control unit with direct I/O support and built-in communication interfaces for industrial environments.
The CX9020-N031 variant is factory-configured with a dedicated RS485 system interface. This interface features a 9-pin D-sub socket configured as an end point with active termination and no echo, allowing direct serial communication with external field devices, legacy controllers, or peripheral instrumentation.
With its automatic bus detection capability, the unit directly interfaces with both Beckhoff Bus Terminals (K-bus) and EtherCAT Terminals (E-bus). This dual-bus support enables flexible, scalable control architectures without requiring separate bus coupler modules.
