# Beckhoff CX7050

Hardware · `CX7050` · verification: source checked

The Beckhoff CX7050 is an embedded PC for control applications. It uses an Arm Cortex-M7 480 MHz processor, runs TwinCAT/RTOS with the TwinCAT 3 runtime, and includes eight multi-functional digital inputs and four multi-functional outputs. It has an Ethernet interface and a CANopen master interface that can also operate as a CAN or CANopen slave.
