CODESYS 3.5 is a modern Integrated Development Environment (IDE) designed for programming and configuring industrial controllers in compliance with the international standard IEC 61131-3. It combines tools for software development, fieldbus configuration, visualization, debugging, and motion control into a single platform.

🔑 Key Functional Features

✔️ IEC 61131-3 Programming

• Support for five standard programming languages:
  • LD (Ladder Diagram)
  • FBD (Function Block Diagram)
  • ST (Structured Text)
  • IL (Instruction List)
  • SFC (Sequential Function Chart)
• Additional extension: CFC (Continuous Function Chart) for convenient algorithm design.
• Extended library system and code reusability.

✔️ Integration and Configuration

• A single environment for:
  • hardware resource configuration,
  • working with fieldbuses (CANopen Manager, Modbus TCP/IP Master, EtherCAT Master, PROFINET Controller, EtherNet/IP Scanner),
  • online project debugging.
• Integration with version control systems (SVN, Git).

✔️ Visualization and SCADA

• The CODESYS Visualization module enables the creation of operator interfaces directly within the IDE.
• WebVisu support for browser- and mobile-based access.
• Development of mimic diagrams, trends, alarms, and control panels.

✔️ Networking and Communication

• Support for industrial protocols: CANopen Manager, Modbus TCP/IP Master, EtherCAT Master, PROFINET Controller, EtherNet/IP Scanner.
• OPC UA, MQTT, SNMP support for integration with IoT and Industry 4.0 (including Weintek HMI devices).
• Possibility to implement custom protocols through libraries.

⚡ Advantages of Using CODESYS 3.5

• 🔄 One environment for all stages: from coding to visualization.
• 🌐 Openness to integration with virtually any equipment thanks to support for hundreds of protocols.
• 🛠 Scalable — from small local systems to complex networked projects.
• 🤝 Active community and access to the CODESYS Store with additional libraries and drivers.

📦 Application Areas

• 🏭 Industrial automation (metallurgy, food, chemical industries).
• ⚡ Energy (dispatching and monitoring systems).
• 🚗 Transport and mobile machinery (control based on CAN J1939, ISOBUS).
• 🏢 Building automation (HVAC, lighting, security systems).
• 🤖 Robotics and integration with IoT platforms.

✅ Conclusion

CODESYS 3.5 is a universal platform for automation engineers, enabling the creation of flexible, scalable, and reliable automation systems. Its main advantage lies in its comprehensiveness: from controller programming to HMI/SCADA development and cloud service integration.

That is why CODESYS 3.5 remains one of the most popular environments in the world of industrial automation.
