[Tweet](https://twitter.com/share) ### Get free online instruction for using the CODESYS runtime engine on *groov* RIO in the new training series. A customer favorite in 2023 was the [*groov* RIO 3.5 firmware release](https://blog.opto22.com/optoblog/opto-22s-groov-rio-levels-up-in-a-major-way-with-codesys). With this release, you could use the *groov* RIO edge I/O module as a controller with the CODESYS runtime engine onboard. This was a game changer for many of our customers. Our Director of Technical Marketing, Dan White, even shared one of the first applications taking advantage of the new RIO 3.5 features in this [CODESYS Tech Talk](https://blog.opto22.com/optoblog/codesys-tech-talk-fall-2023-recap) with Costa Farms.  It illustrated how the addition of CODESYS has transformed *groov* RIO into a full-fledged Edge PLC, opening up a world of possibilities for automation and control. Now you can get a better understanding of how this new feature can work in your application by following along with some [brand-new lessons on OptoU](https://training.opto22.com/path/creating-control-programs-with-codesys-and-groov-rio)—Opto 22's free online training site.  [![RIO\_Codesys\_OptoU](https://blog.opto22.com/hs-fs/hubfs/RIO_Codesys_OptoU.jpg?width=640&height=360&name=RIO_Codesys_OptoU.jpg)](https://training.opto22.com/path/creating-control-programs-with-codesys-and-groov-rio) The new [*groov* RIO with CODESYS series](https://training.opto22.com/path/creating-control-programs-with-codesys-and-groov-rio) includes four lessons: - Getting Started with CODESYS on *groov* RIO - Creating an Empty CODESYS Control Program on *groov* RIO - Running CODESYS Control Programs on *groov* RIO - Applying the CODESYS License to *groov* RIO Be prepared to spend 60-90 minutes on these lessons.
