Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a WAGO part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These series from our supply network is the closest match on published figures.
Kinco compact modular PLC with tool-free slice I/O expansion for space-saving automation.

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.
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 WAGO PFC300 controller
Send these with your enquiry and an engineer can confirm the right PFC300 controller 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
WAGO PFC300 controller: frequently asked questions
What is the WAGO PFC300 controller?
64-bit dual-core (Cortex-A53, 1.4 GHz) PLC with 2 GB DDR4, 32 GB eMMC, two gigabit Ethernet ports, RS-485 and USB-C, running CODESYS V3.5 on Linux with Docker support. It is made by WAGO GmbH & Co. KG; Specify Motion can help source it or propose an equivalent.
Who makes the WAGO PFC300 controller?
The WAGO PFC300 controller is made by WAGO (WAGO GmbH & Co. KG) and is listed here for engineers comparing options. Specify Motion is not affiliated with WAGO GmbH & Co. KG; brand names are used only to identify the product.
Is there an alternative to the WAGO PFC300 controller?
Yes. On published figures, Kinco K6S is the closest match 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.
