H4U.app – Hydraulic know-how in software
H4U.app combines decades of Bosch Rexroth's hydraulic expertise in a sophisticated software architecture. Instead of starting from scratch, you benefit from intelligent controllers and wizards for automated parameterization and system identification. This allows you to achieve stable and precise results faster, shorten commissioning time, and ensure long-term energy-efficient operation of your hydraulic systems. This way, you can achieve stable and precise results faster, shorten commissioning time, and ensure the long-term energy-efficient operation of your hydraulic systems.

Your advantages with H4U.app
Flexible to integrate
With H4U.app, you can flexibly implement your control concepts and seamlessly adapt them to the application, machine, and industry.
The hydraulic functions run on the existing control technology. Engineering and commissioning remain in your familiar automation environment.
This results in an architecture with maximum flexibility for current projects, retrofits, and future expansions.
Easy to start
Get started quickly with H4U.app: Instead of starting from scratch, you can use ready-made software modules that already incorporate Bosch Rexroth's hydraulic expertise.
These can be used for a wide range of hydraulic control concepts, are perfectly matched to our hydraulic components, and offer standardized functionality across all supported automation systems.
This way, you benefit directly from the many years of experience of the industrial hydraulics specialist and from future software developments.
Easy to perform
H4U.app is designed to deliver strong control results and high efficiency from the outset.
The software includes everything needed for this: From automated parameterization and pilot valve zero-point calibration to system identification and intelligent parameter suggestions.
Supplemented by leakage compensation for the pump, the control system remains stable, efficient, and reliably process-oriented in the long term.
Easy to trust
H4U.app makes your investment future-proof: Hardware-independent hydraulic control functions increase both investment security and machine availability because they are decoupled from the product lifecycles of individual control hardware.
Since the integration takes place at the PLC runtime system level, projects with H4U.app can be used for decades – regardless of which control hardware is used in the future.
At the same time, simplified hardware for control tasks can significantly reduce both primary and secondary costs.
Easy to increase uptime
H4U.app specifically contributes to increasing the availability of your machines.
The control system is optimally tailored to Rexroth's hydraulic components and ensures that all components operate within their permissible operating limits.
Integrated temperature and time models, as well as leakage compensation functions, support gentle operation and indicate abnormalities before unplanned failure occurs.
Easy to be up to date
With H4U.app, your hydraulic solutions stay up to date.
The software supports energy-efficient, resource-saving concepts and thus contributes to climate protection and sustainability.
Energy efficiency features such as variable-speed drives and the optimized interaction of all system components ensure that machines and systems are operated in such a way that they experience as little wear and tear as possible and remain economically viable over a long period of time.
