ctrlX OS: Linux-Based OS for Automation


ctrlX OS is a Linux-based operating system designed for real-time use in industrial environments. It's hardware-independent and connects even more automation components to the entire ctrlX AUTOMATION portfolio, including partner solutions from ctrlX World.


Software-based functions can be developed, installed, updated, and operated easily across all levels of the automation topology, catering to the needs of software-driven factories and enabling modern software practices such as virtual testing and DevOps in automation. Hardware independence also makes it possible to operate a virtual control system on hypervisor platforms, in the data center, on edge servers or in the cloud.


The operating system supports app technology, web-based engineering, secure user management, and data exchange via the ctrlX Data Layer. A standardized tool chain and a software development kit (SDK) are available for all devices. The ctrlX Device Portal allows effective device management anywhere in the world. This is a digital service for providing new software functions, management, and maintenance of device settings or remote maintenance.


ctrlX OS provides access to all apps from the ctrlX Store and the ctrlX AUTOMATION Community. Users can also run their own software on any hardware that is suitable for the application.
