What is CODESYS SoftPLC? Why It Massively Reduces Hardware Costs in Automation Projects

As industries transition into the era of Smart Factories and Industry 4.0, developing Automation Control systems has become increasingly complex, requiring the management of massive amounts of data. A classic problem engineers and business owners often face is "sky-high PLC hardware costs" and being trapped by "Vendor Lock-in."

But today, technology has changed. The arrival of CODESYS SoftPLC is revolutionizing the automation industry. This article will take a deep dive into what SoftPLC is and why it has become the "key" to massively reducing costs in industrial projects.

What is CODESYS SoftPLC?

SoftPLC (Software PLC) or PC-based Control is the use of "software" to simulate the functions of a traditional PLC (Programmable Logic Controller) on an Industrial PC (IPC) or even general embedded devices. This allows standard computer hardware to perform real-time machine control just like expensive, dedicated hardware PLCs.

CODESYS is a world-class software platform used to develop programs according to the IEC 61131-3 standard (supporting languages like Ladder, ST, FBD, etc.). When CODESYS is implemented as a SoftPLC, it instantly transforms that hardware into a powerful, intelligent controller.

Why Does CODESYS SoftPLC Massively Reduce Automation Project Costs?

1.Breaking the "Vendor Lock-in" Barrier (Hardware Independence)

In the past, if you used Brand A's PLC, you were forced to buy Brand A's expansion modules and HMI screens at fixed, premium prices. However, with the capabilities of CODESYS SoftPLC, you can choose any brand and specification of Industrial PC available in the market. This gives you the freedom to control your hardware budget and get the absolute best value for your investment.

2. An All-in-One Platform

Traditional automation systems often require purchasing multiple separate devices, such as:

• Hardware PLCs for logic control
• HMI screens for visual display
• Motion Controllers for motor axis control
• Gateways for sending data to the Industrial IoT (IIoT)

But with CODESYS SoftPLC, you can run PLC programs, create visualization displays (WebVisu), control Motion/CNC, and send IoT sensor data to the Cloud—all within a single Industrial PC. This saves massive amounts of money on equipment and complex wiring costs.

3. Higher Processing Performance at a Lower Price

Today's Industrial PC (IPC) CPUs offer processing speeds many times faster than traditional PLC CPUs, at a similar or even lower price point. Using a SoftPLC allows you to smoothly process large amounts of data, such as complex algorithms or Machine Vision systems, without needing to purchase extra, specialized processing modules.

4. Supports Diverse Industrial Protocols Without Extra Communication Cards

SoftPLC via CODESYS typically utilizes the standard Ethernet ports of a PC, which instantly support modern industrial protocols like OPC UA, EtherCAT, PROFINET, Modbus TCP, and MQTT. This enables seamless connection to industrial sensors and IIoT systems without the need to pay for expensive, add-on communication cards.

Ideal Use Cases for SoftPLC

• Complex Machinery: Such as CNC machines, Delta Robots, or systems that require high-speed processing in conjunction with Machine Vision Sensors.
• Smart Factory and IIoT Data Logging: Tasks that require extracting data from existing legacy machines and sending it to the Cloud or SCADA systems for OEE (Overall Equipment Effectiveness) analysis.
• Budget-Constrained Yet High-Performance Projects: Retrofitting old machines to make them modern without spending a fortune on tearing down and replacing the entire control cabinet.
