Beckhoff CX9240 | Embedded PC with Arm® Cortex®-A53

The CX9240 Embedded PC is a compact, DIN rail-mountable Ethernet control system

with a 1.2 GHz Arm® Cortex®-A53 CPU. It represents a further development of the

existing CX9020 and relies on a faster CPU with four cores and a modern 64 bit 

architecture. The multi-core CPU allows PLC projects to be distributed to several cores

for significantly enhanced performance.

The CX9240 features two independent 1 Gbit Ethernet interfaces, which enable

significantly higher transfer rates compared to its predecessor. The main memory

comprises 2 GB LPDDR4 RAM, which doubles the capacity of the compact controller

and, together with the more modern CPU and the same low power consumption,

opens up new application areas and possibilities for the CX9240.

The main features of the CX9240 device series include:

• high-performance 1.2 GHz Arm® Cortex®-A53 CPUs with four cores

• 2 GB LPDDR4 RAM

• two independent 1 Gbit Ethernet interfaces

• DisplayPort instead of DVI

• Beckhoff RT Linux®

• built-in capacitive 1-second UPS

• electrically isolated 24 V DC power supply

Further standard features of the CX9240 include four USB 3.0 interfaces, a DisplayPort,

and a multi-option interface that can be flexibly assigned ex factory – for example,

 with a serial port or a fieldbus connection.

The boot and storage medium is an interchangeable, industry-standard microSD card,

which can be accessed via a slot on the front of the housing. This is used to store not

only the operating system, but also TwinCAT and user projects. Beckhoff RT Linux® is

used as operating system.

The TwinCAT automation software transforms the CX9240 system into a high-performance

PLC and motion control system that can be operated with or without visualization.

Optionally, the unit can be ordered with a fieldbus or serial interface.

The connection for the Beckhoff I/O systems is directly integrated into the CPU module.

The device offers automatic bus system identification (E-bus or K-bus) and switches to

the corresponding mode. The extended operating temperature range between-25°C and

+60°C allows it to be used even in climatically demanding situations.
