CONTROL SYSTEM DESIGN WITH PETRI NETS
Automation solutions with Heron are designed on the basis of Petri nets, which are interpreted in the sense of the control system paradigm. During runtime Petri nets are presented by Auriga/WPF as an interactive GRAFCET model. Discrete-event models of plant and control are described in the canonical description format KBF and stored in XML files whose authenticity can be safeguarded by a digital signature.

HERON OF ALEXANDRIA
In his work Automata Heron described a door control which opens a temple door when a fire is lit. Heron also invented machines for Greek theaters which could perform several movements with the aid of unwinding ropes. He designed a holy water automaton which dispenses a small amount of holy water after a coin has been inserted. His inventions, however, have been forgotten and were never developed further.
