Coping with evolution in automated production systems implies a cross-disciplinary
challenge along the system's life-cycle for variant-rich systems of high complexity. The …

Programmable logic controllers (PLCs) are heavily used in industrial control systems,
because of their high capacity of simultaneous input/output processing capabilities …

This paper presents the core concepts for PLC-statecharts–an adaptation of UML-
statecharts–which can be used as a visual programming language for PLCs. They combine …

Automated machines and plants are operated for some decades and undergo an
everlasting evolution during this time. In this paper, we present three related open evolution …

To facilitate engineering and evolution of automation systems, ensuring the correctness of
the design models is an important topic. Industrial automation systems are composed of …

This paper presents a novel approach to evaluate the response time in networked
automation systems (NAS) that use a client/server protocol. The developments introduced …

The introduction of Ethernet and Internet technologies in the fieldbuses of automation
systems widely facilitates vertical integration. Control functions can coexist more easily with …

Разработана модель сегмента отделения АСУТП АЭС, верифицирован способ
расчета временных характеристик системы при худшей комбинации входных условий …

In this paper, we present an analytic approach to evaluate the reactivity of client-server
networked automation systems (NASs). Both deterministic and probabilistic analyses are …

In this paper, an approach to evaluate time performances of networked control systems
(NCSs) is presented. Switched Ethernet with a client/server protocol is considered for …
