What / Why CODESYS

What Exactly is CODESYS?
CODESYS is a comprehensive development suite used for programming controller applications. The platform’s core is the IEC-61131-3 programming tool called the “CODESYS Development System”. It is a platform-independent development environment compatible with PLC hardware and many other automation components available from hundreds of companies, making it a versatile solution that helps users implement various tasks.

Why Use Codesys?

There are a lot of reasons, but we will cover just a few below:

• Every one of the five PLC programming languages covered by the IEC 61131-3 standard — ladder diagram, function block diagram, sequential function chart, structured text, and instruction list — is supported by CODESYS. This created a uniform system that supports a huge number of PLCs and automation components being used by a company, allowing system designers to work within any one of them as needed. This simplifies the integration of new products into a system.
• There are over a million different devices from over 400 manufacturers that are compatible with CODESYS. Including Wago, OPTO22, Turck, and many others.
• Optional add-on modules for methodical application development, including UML, version management, and test automation.
• Installation, maintenance, and training required only for a single user interface: Minimization of engineering effort.
• No need to reinvent the wheel. There is a library of reusable function blocks and code samples to pull from.
