From Vision to Mission to Process
HES - Haf Engineering Services (C2Pi) develops and manufactures scalable IoT process interfaces and modular kit systems that act as a link between virtual information on an IoT device or in the cloud and any physical process. The IEC61131-2-compliant interface hardware makes existing machines internet-capable and connectable and is particularly suitable for retrofitting existing installations. The product range extends from the circuit board for in-house production, through versions for training and education, to the complete solution in an IP housing (1-litre control cabinet, manufactured by 3D printing) for the control and automation of industrial processes. In addition, the company offers customised Linux distributions and the web-based control centre C2Pi-GO as well as operating system distributions such as C2Pi OS. Customers are companies in the fields of Industry 4.0, IoT/IIoT and SmartHome as well as educational institutions. The sole proprietorship is based in Schwaikheim near Stuttgart.

Hardware and Software Platforms
Compliant IO hardware
Industrial-grade, standards-compliant interface hardware with 2x4 high-side outputs and 8 digital inputs.
Single-board computers
The C2Pi is platform-independent and works with single-board computers such as RaspberryPi, Banana Pro, ODROID and BeagleBone with compatible GPIOs.
Microcontroller platforms
Also available for microcontroller platforms based on Arduino nano.
Additive manufacturing
Additively manufactured housings for the 1-litre control cabinet.
Customised Linux distribution
C2Pi OS as an operating system dialect and the web-based control centre C2Pi-GO for easy device management.
