The B&R X20CP3584 CPU module is the X20 system's central controller, built around an Atom processor at 0.6 GHz and equipped with 256 MB DDR2 RAM and 1 MB SRAM. Application memory is stored on removable CompactFlash, enabling portable programs and data for field upgrades. The unit runs from 24 V DC with a maximum current of 1.5 A and uses passive cooling, making it suitable for rugged industrial environments. Onboard interfaces include RS232, Ethernet, POWERLINK, USB, and X2X LINK, supporting fieldbus and network communications, while built-in diagnostics such as battery status, CPU function, CompactFlash status, Ethernet, POWERLINK, and overtemperature help monitor operation.
