CODESYS
CODESYS is an industrial software platform used for developing and runtime systems for programmable logic controllers. It allows creating control applications based on the IEC 61131-3 standard.
CODESYS: Industrial Software Platform
Develop and run industrial automation systems with CODESYS, a platform conforming to IEC 61131-3 standards for programmable logic controllers.
What is CODESYS?
CODESYS (Controller Development System) is an industrial software platform used for developing programmable logic controller (PLC) applications and runtime systems. It fully complies with the IEC 61131-3 standard for PLC programming languages and allows creating control applications for a wide range of automation devices.
Some key features of CODESYS include:
- Supports all 5 IEC 61131-3 programming languages - Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL), and Sequential Function Chart (SFC)
- Includes an integrated development environment (IDE) for writing, testing and debugging PLC programs
- Allows target system independent programming - the same application code can run on different hardware targets
- Comes with visualization and HMI development tools for operator interfaces
- Features built-in communication drivers for industrial protocols like Ethernet/IP, Modbus, CANopen etc.
- Offers functionality for version management, application distribution and remote debugging
- Available on a variety of hardware platforms from several automation device vendors
In summary, CODESYS provides a flexible and standardized software environment for developing industrial control systems irrespective of the target device hardware.
