DEUTA HMI Safety Package

The safety upgrade for standard terminals

DEUTA has developed a safety upgrade for standard terminals. The HMI safety package is assessed according to the basic safety standard for functional safety IEC61508 meeting the requirement SIL3 for safe display and for the safe data entry SIL2.


Safe display & operation (SIL3/SIL2)

The HMI Safety Package is designed so that safety technologies for safe display and safe operation are integrated with minimum effort in existing HMI devices.

HMI Safety Package consists of the modules: IconTrust board and photo sensor unit. 

Together, these modules provide the basic function of safe a display:

  • The IconTrust board supervises the video data stream and compares it with safe process values transferred via a safe communication channel.
  • The photo sensor unit supervises the correct functioning of the display panels. The optional elements: touch, keyboard and computer mouse constitute the safe input functions up to SIL2.

The package is completed by the design erference guide and the configuration tool IVEN.

The HMI Safety Package which has already been assessed according to IEC61508 standard, minimises the effort for the assessment of the entire appliance. The HMI Safety Package with the safe communication protocol (e.g. PROFIsafe) offers the possibility to achieve an individual safety solution with standard components.


Safe display with IconTrust®

As part of the HMI Safety Package, IconTrust supervises dedicated areas on the TFT panel and differentiates between safety-relevant and non safety-relevant information up to PL-e or SIL 3:

  • supervises dynamic and static areas on the HMI panel 
  • recognizes the validity of displayed information 
  • confirms the receipt of the current process data via a safe connection 
  • compares the displayed process value with the input process value

Safe operation with SelectTrust® & MouseTrust®

The SelectTrust and MouseTrust technologies enable a safe touch input with the Performance Level PL-d or SIL 2. The input areas shown on the display are safely supervised. With actuation, a respective safe data protocol is generated – completely independently and in parallel to the processing of non-safe input data by the HMI.


More safety when it counts!

When human lives are at stake, process sequences are system relevant or within a hazard zone, trust technologies are monitoring inside the HMI Safety Package the display and operation at the terminal:

  • Command and control centres
  • Inspection centres
  • Operating terminals
  • Production control
  • Maintenance work
  • ...
