This work is motivated by the fact that many real systems are characterized by two features. The first one is that they are obtained by interconnecting a bunch of simpler subsystems that have to synchronize in order to reach a global goal. The second one is that each subsystem presents dynamics that evolves on different time-scales. Taking into account the two features leads to the problem of synchronization...
Since the photovoltaic systems development is growing exponentially, the policies related to grid integration will also have to change so that more and more PV systems can be accommodated in the grid. This paper discusses existing Central Electricity Authority (CEA) technical interconnection regulations. As PV penetration increases the CEA can reevaluate the existing operating range for voltage and...
The field bus systems have been applied to the industrial automation. PROFINET is an optimized industrial network standard. It provides the service definition and protocols for real-time communication based on Ethernet. The basic characteristics and protocol analysis are presented in this paper. This paper depicts a topology model using Wire shark and Siemens PLC to capture PROFINET IO communication...
Semi-custom design flows are a key factor for the rapid growth of integrated circuits and systems. They lower design complexity through the use of pre-designed and pre-characterized functional components called standard cells, instead of assuming that designers have to draw, place and connect each transistor. In this way, modeling of complex systems is easier. As CMOS technologies evolve into deep...
Mechatrolink-III is a real-time Ethernet protocol designed to achieve high performance with short cycle time. The Mechatrolink-III protocol includes five communication phases: synchronization, cyclic communication, retry communication, C1 master message communication, and C2 master message communication. These communication phases directly affect the cycle time of Mechatrolink-III. This paper analyzes...
This paper presents the mapping of the High-Availability Seamless Redundancy (HSR) protocol to PROFINET RT. Whereas common PROFINET RT components that implement the Media Redundancy Protocol (MRP) are requiring up to 200 ms for recovery after link failures, HSR provides seamless redundancy. In order to overcome the incompatibilities between PROFINET and HSR a configurable HSR RedBox is implemented...
The development of an open architecture for multimedia data integration and visualization in template based distributed applications is a challenge for the scientific researches. Because of characteristics of multimedia data, their management and querying techniques are unlike than those of traditional data. We can increase the potential use of multimedia data across various applications by storing...
