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.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eCX9020-N031\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n
