In this article known methods of design fieldbus network in distributed control system (DCS) are analyzed and the synthesis of new algorithm is presented. Building a network is made in the condition of strict restraints on cost, as well as probabilistic and temporal characteristics of the information exchange. The analysis is conducted for fieldbus networks, based on methods of random multiple nodes...
The article describes state-of-the-art models and methods to estimate probabilistic and temporal characteristics of distributed control systems (DCS), based on industrial real-time networks, or fleldbuses. Conducted review and synthesis of recent publications shows the lack of information about using of integral criteria for DCS performance evaluation. Being implemented at the example of LonWorks...
The problem of countering one of most dangerous unconventional information security threats for modern industrial control systems covert channels is considered. A universal method of countering such a threat based on earlier unknown formal condition of existence of covert channels is proposed. An illustration of the method to counter covert channels in a real industrial control system is given.
We study the coupled translational, electronic, and field dynamics of the combined system ''a two-level atom+a single-mode quantized field+a standing-wave ideal cavity''. In the semiclassical approximation with a point-like atom, interacting with the classical field, the dynamics is described by the Heisenberg equations for the atomic and field expectation values which are known to produce semiclassical...
