Where can I get the Software Development Kit (SDK) for ctrlX AUTOMATION?

The official release of the SDK for ctrlX AUTOMATION is available as download via GitHub.

Prototype versions will be available for selected customers via download from Collaboration Room.

To become a selected customer please contact any person at Bosch-Rexroth sales- or business development department. Link to contact search (At Product Groups please select only "Electric Drives and Controls")



The SDK contains all information and dependencies you need to start to develop additional software packages for ctrlX AUTOMATION. If we talk about software packages it means snaps. Snaps are app packages for desktop, cloud and IoT that are easy to install, secure, cross-platform and dependency-free -

With the samples containing our SDK you learn to build those packages for our new platform ctrlX CORE or ctrlX COREvirtual , from scratch. Don't be afraid and try it! 🙂

Which examples can be found in the SDK (1.10.0) for ctrlX AUTOMATION?
  • Samples C/C++:
    • Hello World --> print "Hello World" in the console and diagnostic logbook
    • Hello PLC --> write PLC symbol variables NRT
