Embedded HMI – parallel development made easy

In a classic HMIs, status displays, and command input are separated from the control unit or PLC.

Our embedded HMI, in contrast, combines all functions on the “front end”. With this “intelligence” directly at the interface to the operator, we reduce the load of the controller – the same time enabling two teams to work in parallel on HMI and core application.

For many of our customers, this is an important aspect: due to this functional separation, no knowledge and know-how transfer regarding the core application is required. Both teams use their experience and knowledge in the right places. This shortens time-to-market and helps to keep development costs under control.

CARY – the smart modular construction kit for your individual health management system

Protecting our employees from health hazards in the workplace is our top priority. As a family-run company, we rely in these times on a smart protection concept that works reliably, fulfils the legally required verification and documentation obligations and is so easy to use that employees are happy to accept it.

Comprehensive solution for manufacturing companies

Because such a system, suitable for medium-sized manufacturing companies, was not available on the market, we developed CARY ourselves in a very short time. Our own comprehensive solution construction kit for HMIs gave us outstanding support as we did not have to develop numerous subsystems from the scratch, such as environmental sensors, anti-microbial coating of glass or RGBW-LED lighting.

The advantages of our CARY at a glance:

• CARY reduces risks
• CARY provides safety
• CARY reduces costs
• CARY simplifies communication
• CARY makes processes lean and efficient
• CARY easily communicates with the building automation
• CARY is open für future extensions – and an irreplaceable assistant not only in pandemic times

Data protection and acceptance

The straight-forward, elegant design takes the latest findings in usability research into account and sets milestones in the digitalisation of documentation and testing requirements. We have placed special emphasis on data security – and still managed to ensure open interfaces in order to enable system integration of CARY practically everywhere. See for yourself!

If you imagine a sectional view through a modern HMI, several layers lie one behind the other in the direction of the user’s gaze. First the cover glass, then the ITO sensor, which detects the position of the finger(s), then the display.

In school, we learned in physical optics that reflections always occur at the contact surfaces of materials with different optical densities. This is exactly the case in our mental cross-section through the HMI. If you simply place the individual layers one behind the other, there is air in between. Disturbing reflections occur at the contact surfaces of glass and air, which impair perfect readability.

To prevent this, all the gaps are filled with a synthetic material in a clean-room environment. This filler material has the same optical properties as glass. Thus, a ‘pile of panes with air in between’ becomes a single pane with constant optical density. The density jumps at the glass/air transitions are eliminated – and with them the disturbing reflections.
