Operating and monitoring concepts (Human Machine Interface)


One important aspect for FlexSILon BCS solutions is the definition of the Human Machine Interface, since the safety-relevant firing processes must be completely controllable at all times.

We have the knowledge and experience required to incorporate individual HMI solutions into our supply scope, without necessarily having to rely on a hardware platform. The HMI hardware platform can be geared to the requirements in the system or to specific functionalities.

Expansions, such as through first value/new value graphics or SER (Sequence of Event Recording) alarm pages, in which the time-stamped fault texts are chronologically listed, are common in firing technology and are also available from us upon request. In addition, the faults or events are time-stamped in our safety-relevant systems, which can be synchronized as a time master or as a time extension via SNTP (see also HIMax and HIQuad systems). A special input and acknowledgement procedure enables process parameters and possibly safety-relevant parameters to be changed via non-fail safe HMI.

These procedures are supported innately in our TÜV-tested and approved function blocks using special data structures.

HIMA application engineers guarantee that the primary goals are achieved in all cases

  • Optimum transparency
  • Rapid analyses and evaluations
  • Optimization of the energy-generation process

The experience we have garnered with HMIs over many years' of working with FlexSILon BCS shows that the graphics below represent valuable support for the plant operators.
