5 Advantages of Using Codesys in Industrial Machine Control Systems

Codesys is the international standard software (IEC 61131-3) trusted by engineers worldwide as Thailand’s industrial sector moves toward Industry 4.0. In this era, automation control is no longer just about making machines run—it must also prioritize flexibility, data connectivity, and long-term cost-effectiveness. Today, we delve into the 5 primary advantages that give Codesys a competitive edge over traditional PLCs in every dimension.

1. Hardware Independence

The most prominent advantage of Codesys is its status as an "Open System." It supports over 400 controller brands worldwide, allowing business owners to end "Vendor Lock-in." If a specific brand’s hardware is out of stock or prices rise, you can switch to another brand running Codesys immediately without rewriting your entire program.

2. Globally Recognized Standard (IEC 61131-3)

Codesys integrates all standard programming languages into one platform, including:

• Ladder Diagram (LD): For technicians familiar with relay logic.
• Structured Text (ST): For complex calculations similar to C++ coding.

Sequential Function Chart (SFC): For organizing machine sequences. This multi-language support makes system design faster and more organized.

3. Built-in Future Technology and IIoT Support

Building a Smart Factory requires sending machine data to the Cloud or ERP systems. Codesys includes advanced communication functions such as OPC UA, MQTT, and Web Visualization (monitoring via browsers). This simplifies Data Logging and Remote Monitoring while significantly reducing the cost of additional accessories.

4. Efficiency through Object-Oriented Programming (OOP)

Codesys simplifies complex code management through its OOP capabilities. Engineers can create standardized Function Blocks for reuse, reducing debugging time and making long-term maintenance easier, even as production lines expand.

5. Better Total Cost of Ownership (TCO)

By reducing software licensing fees and enabling seamless system integration across multiple brands, Codesys significantly lowers installation and maintenance budgets compared to closed, proprietary systems that require expensive, specialized equipment.
