Product information
Product Overview
The CX9020 is an Arm Cortex-A8 (1 GHz) DIN rail controller with 1 GB DDR3 RAM, a microSD-based flash concept and a DVI-D output for a local operator display. The configuration offered here is CX9020-0111: Windows Embedded Compact 7 with the TwinCAT 2 PLC runtime.
It is the current-generation Arm controller for machines that want a modern, fanless, PC-architecture controller with a display output, without moving to a full Windows IPC.
Why Buyers Specify This Model
The “-0111” suffix — confirmed on Beckhoff’s own ordering table
Beckhoff lists five CX9020 CPU module order codes: -0100 (no operating system, no TwinCAT), -0110 (Windows Embedded Compact 7, no TwinCAT), -0111 (Windows Embedded Compact 7, TwinCAT 2 PLC runtime), -0112 (Windows Embedded Compact 7, TwinCAT 2 NC PTP runtime) and -0115 (Windows Embedded Compact 7, TwinCAT 3 runtime XAR, no licences included).
So -0111 is the one that ships with a working PLC runtime and no separate licence purchase. Note the contrast with -0115: that code gives you TwinCAT 3 XAR but explicitly without licences.
Arm Cortex-A8 means no fan and no rotating media
Cooling is passive and the flash concept is a microSD card slot (512 MB included, optionally expandable to 16 GB, with 32 GB and 64 GB listed by Beckhoff as announced for Q4 2026). Maximum power consumption is 5 W, rising to 9 W with a loading UPS.
Compared with the x86 CX5020 generation, the Arm platform draws less power and produces less heat for the same control task. For a sealed cabinet that is the difference between needing ventilation and not needing it.
Interfaces and optional fieldbus modules
The basic module provides 2 × RJ45 10/100 Mbit/s (internal switch), 1 × DVI-D and 4 × USB 2.0, plus one optional interface slot. Beckhoff’s optional interface list covers RS232, RS485/RS422 in several termination variants, EtherCAT slave, PROFIBUS master and slave, CANopen master and slave, and PROFINET RT controller and device.
The optional interface is a factory-fitted order item, so it must be chosen at the time of ordering — it cannot be added later in the field. If your application needs PROFIBUS or CANopen, that has to be in the order code.

Lifecycle and Successor Models
In production. The CX9020 is listed in Beckhoff’s current catalogue and its official product page is live. It is also the model that Beckhoff explicitly names as compatible with the CX2900-0107 device modification for ATEX, IECEx and cFMus use.
Newer Arm families (CX7000, CX81xx, CX82xx) sit alongside it. For new designs it is worth comparing them; for installed CX9020 machines, this is the replacement.

Ordering This Part
Tell us the model and, where an order code exists, the complete code — Beckhoff variants differ in ways that matter, as set out above. For discontinued models, a nameplate photograph is the fastest way to confirm exactly what you have.
- Exact model or order code (including any suffix such as
-0111or-ESvariants) - Quantity required
- Whether you need the terminal alone or a complete station with coupler and power supply
- For replacements: a photo of the existing nameplate or the old order code
We confirm availability and condition before quoting. We do not publish stock levels or lead times on this page because they change; ask and we will answer specifically for your requirement.
Frequently Asked Questions
What exactly is CX9020-0111?
Per Beckhoff’s ordering information: CPU module with Windows Embedded Compact 7 and the TwinCAT 2 PLC runtime. Other CX9020 codes are -0100 (no OS), -0110 (WEC7, no TwinCAT), -0112 (WEC7, TwinCAT 2 NC PTP) and -0115 (WEC7, TwinCAT 3 runtime XAR, no licences).
Can I add a PROFIBUS or CANopen interface later?
No. The optional interface is factory-fitted and must be specified at ordering time. Beckhoff lists RS232, RS485/RS422 variants, EtherCAT slave, PROFIBUS master/slave, CANopen master/slave and PROFINET RT controller/device as the available options.
What display can I connect?
The basic module has a DVI-D output. Beckhoff also lists CP-Link 4 and DVI-D display cables in the CX9020 accessories, because DVI-D over long cable runs typically needs the right cable construction.
How much memory does it have?
1 GB DDR3 RAM, which is not expandable, plus 2 microSD card slots with a 512 MB card included. 16 GB is the current expansion option; Beckhoff lists 32 GB and 64 GB cards as announced for Q4 2026.
Is the CX9020 a current product?
Yes, it is in Beckhoff’s current catalogue. It is also the model listed for the CX2900-0107 ATEX / IECEx / cFMus device modification.
