One HMI Platform – Flexible, Intuitive and Efficient
Flexible HMI Solution for Automation Tasks
Rapid adaptability, machine networking and decentralized automation designs continue to shape modern manufacturing. ctrlX HMI provides the foundation for software-defined flexibility and operator-friendly usability, from compact HTML5-capable web panels to powerful devices for more complex processes. HTML5-based visualization can run independently of hardware and across platforms, helping machine builders standardize the operator experience across different device types.

CDI+ Single Cable Solution
The CDI+ interface expands ctrlX HMI installation possibilities by transmitting both video and touch functions over a single cable. Bosch Rexroth states that this can be used over distances of up to 100 meters, simplifying installation while supporting clean, reliable communication between the HMI and IPC.
Web HMI Solutions from ctrlX World
Web HMI solutions from ctrlX World partners enable individualized visualization for different machine and system types. With HTML5 web technology and a central HMI server unit on ctrlX OS, HMI interfaces can run on ctrlX HMI devices independently of the operating system. The free HMI base template also helps reduce development effort by providing image elements for functions such as navigation, machine diagnostics and recipe management.
