Overview
Beckhoff TwinCAT 3
TwinCAT 3 turns your industrial PC into a powerful real-time controller. You can integrate all your automation tasks—from PLC and motion control to safety and HMI—into a single, unified environment. By using the eXtended Automation Architecture (XAA), you can program your machines using familiar industrial standards like IEC 61131-3 alongside high-level languages like C or C++. This flexibility allows you to build more sophisticated machines while keeping your development process streamlined.
You can manage your entire project lifecycle within Microsoft Visual Studio, which simplifies version control and team collaboration. Whether you are building a small packaging machine or a massive production line, the software scales to meet your performance needs. It helps you reduce hardware costs by consolidating multiple controllers into one PC-based system, giving you more processing power for demanding applications like vision processing and machine learning.
CODESYS
CODESYS provides you with a complete development environment for industrial automation. Instead of being locked into specific hardware, you can program controllers from different manufacturers using a single, standardized tool. You can develop applications using all five IEC 61131-3 programming languages, allowing you to choose the best method for your specific logic needs, whether it is ladder logic or structured text.
The platform handles everything from basic PLC programming to complex motion control and safety functions. You can also design integrated web-based visualizations to monitor your machines from any device. It is widely used by machine builders, system integrators, and hardware manufacturers who need a flexible, professional-grade environment to manage modern industrial internet of things (IIoT) requirements.
Overview
Beckhoff TwinCAT 3 Features
- Visual Studio Integration Program your automation projects directly within Microsoft Visual Studio to use professional IT tools for versioning and debugging.
- Multi-Core Support Distribute your automation tasks across multiple CPU cores to maximize the performance of your industrial PC hardware.
