# *groov* RIO offers CODESYS control to distributed, remote Ethernet I/O

### You can develop control applications on *groov* RIO with the free CODESYS development environment and the optional CODESYS runtime.

Use *groov* RIO as a PLC. In 2023, the CODESYS runtime was added to the *groov* RIO family, allowing you to use this flexible, software-configurable I/O system in control applications. 

Security, control programming, and software-configurable I/O are now in the same compact *groov* RIO edge device. The on-board CODESYS runtime engine fully supports IEC-61131-3 control programs written in the programming language of your choice: structured text, ladder logic diagram, functional block diagram, and continuous or sequential function chart.

Want to learn more, and discuss your project with an Opto 22 Application Engineer? Please provide your contact information at the right or below, and an engineer will reach out to you.
