IconTrust is the generic solution for all TFT displays that need to meet SIL requirements. This includes, e.g., displays in driver's cabs and controller equipment in rail transport.


IconTrust® can be extended with:


SelectTrust® - for safe manual input of correct information

TouchTrust® - for safe redundant multichannel read-out of touch events

SignalTrust® - for safe  supervision of color signals, backgrounds or screen areas

Infinite control of a TFT-panel

IconTrust supervises dedicated areas on the TFT panel and differentiates between safety-related and non safety-related information. To display image areas with safety-critical information, IconTrust configures dynamic and static monitoring areas.

The innovative technology simultaneously and independently supervises the safety-critical areas, and in case of deviations, triggers a corresponding safety-oriented response. Each of the individual areas of the displayed image is analyzed and compared to the value of the respective input variable during every image refresh cycle.

The patented procedure demonstrably secures topicality and correctness without subjecting the actual application that presents the information to a corresponding verification procedure. Because of this independence, there are no limits to deploying IconTrust.

Display error detection is essential

Most system designs for control stations concentrate by default on the validation of the electronic process control computer according to SIL requirements (Safety Integrity Level). However, the safety gap in the digital displays often remains open. The cause of the error may lie in the display of corrupted data which operators on-site and in controlled operations cannot validate in real time. At best, the system is impaired or malfunctions; at worst, lives are put at risk. This means that for every safety-relevant manually operated display and control system, appropriate corrective action for error recognition is indispensable. With IconTrust, a technology is now available which supervises and reveals potential errors on TFT displays, using a PC-independent circuit. IconTrust derives the data sets as a finger print of the information currently being displayed. In this way, discrete pieces of information can be supervised independently and exclusively in various areas of the screen. Cost-effective IconTrust technology is universally suited for all applications with safety-relevant display of information, for example, in the cockpits of modern trains, in control rooms or manned surveillance systems. IconTrust can be used as a panel PC, a TFT monitor or a projector. It can also be integrated easily as an add-on into existing devices.

Which input signals does IconTrust monitor?

In principle, all types of input signals can be supervised with the IconTrust technology. These can be represented as symbols, needle instruments or bar graphs, letters, text or color play. If required, it is possible to allow different screen representations for one and the same value of the same input signal (equivalent representations). Alongside, the configuration of an error counter for the delayed triggering of the safety reaction can be selected.

Considerably more flexible

With IconTrust, display type and layout can also be modified in a flexible and uncomplicated way into safety-relevant areas. If the application is in the process of being developed or adapted for a new requirement, safety can be reconfirmed without a lengthy qualification process.

Permanently more reliable

IconTrust is a safe, reliable, flexible and cost-effective technology for the constant control of TFT-displays in safety-critical applications.
