Fieldbus/Ethernet function integration

With valve terminals, control systems, controllers and much more, Festo is always well connected


Whatever communication concept and bus architecture you choose, Festo's valve terminal range and electrical peripherals can be adapted to virtually all networking tasks.


Our valve terminals are open to all fieldbus protocols and also provide comprehensive diagnostic and energy management functions. For example, as a fully flexible automation platform, CPX supports the integration of electrical and pneumatic components, motion control and networking components.


More than 20 fieldbus and Ethernet protocols and more than 20 years of experience make Festo the world's no. 1 for intelligent pneumatics.
