The comprehensive software suite for automation technology

Independent of device manufacturers

The basis:

The "CODESYS Development System" programming tool, which implements the international IEC 61131-3 standard
The control software ("PLC runtime system" or "SoftPLC" or "virtual PLC") for different device platforms

With CODESYS, you can freely select the optimum hardware for your automation application. Many classic automation providers have already implemented CODESYS. Or you can use standard device platforms on which you simply install or deploy the appropriate control software. With virtual controllers, you can even use powerful IT hardware for control and thus reduce hardware costs.

CODESYS in Use

CODESYS in factory automation, mobile machinery, the energy industry, embedded devices, process and building automation.

With CODESYS, Lissmac was able to achieve maximum independence from device manufacturers. The development of a new user interface based on Lissmac CI was very simple. With WebVisu, diagnostic data can be retrieved globally and in real time via remote access.
