Beckhoff Automation CX Embedded PCs replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Beckhoff Automation part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.
Kinco compact modular PLC with tool-free slice I/O expansion for space-saving automation.
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
Typical applications
What a PLC is
A PLC, or programmable logic controller, is an industrial computer that runs machine control programs, reads inputs and drives outputs in a repeating scan cycle. Programs are written in IEC 61131-3 languages such as ladder diagram, structured text and function block diagram. Modern PLCs also handle communication over fieldbus and industrial Ethernet, data logging and motion control functions. Formats range from compact bricks with built-in I/O to modular racks and industrial PCs.
When engineers choose a PLC
Choose a PLC as the main controller for machines and process systems needing reliable logic, sequencing, I/O handling and communication. It is robust, widely supported and familiar to maintenance teams. The trade-offs are motion capability and cost: entry-level PLCs offer limited axis control, so complex multi-axis motion may need a motion controller or PLC with motion libraries. Ecosystem and software licensing should be considered too.
How to specify the Beckhoff Automation CX Embedded PCs
Send these with your enquiry and an engineer can confirm the right CX Embedded PCs variant or an equivalent:
- I/O count and types
- Programming languages and software
- Communication interfaces and protocols
- Motion axes, if needed
- Scan or cycle time
- Expansion and modularity
- Power supply and environment
Common mistakes to avoid
- Choosing a PLC without enough I/O or memory for growth
- Ignoring software licensing costs
- Assuming all fieldbuses are supported
- Leaving out cybersecurity for networked machines
Beckhoff Automation CX Embedded PCs: frequently asked questions
Can you help replace Beckhoff Automation CX Embedded PCs or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Beckhoff Automation CX Embedded PCs?
DIN-rail industrial PCs running TwinCAT that act as PLC and motion controller, scaling from small Arm-based units to multi-core Intel Xeon and AMD Ryzen models. It is made by Beckhoff Automation GmbH & Co. KG; Specify Motion can help source it or propose an equivalent.
Who makes the Beckhoff Automation CX Embedded PCs?
The Beckhoff Automation CX Embedded PCs is made by Beckhoff Automation (Beckhoff Automation GmbH & Co. KG) and is listed here for engineers comparing options. Specify Motion is not affiliated with Beckhoff Automation GmbH & Co. KG; brand names are used only to identify the product.
Is there an alternative to the Beckhoff Automation CX Embedded PCs?
We can assess suitable replacement options. On published figures, Kinco K6S is options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
What is IEC 61131-3?
IEC 61131-3 is the international standard for PLC programming languages. It defines ladder diagram, function block diagram, structured text and sequential function chart, plus program organisation. Programs written to the standard are more portable between platforms, though vendor differences remain.
Can a PLC control servo motors?
Yes, many PLCs control servo drives using motion function blocks, pulse outputs or a real-time network such as EtherCAT. Simple PLCs handle a few axes, while PLCs with motion libraries handle coordinated motion. Check axis count, network support and cycle time.
