The main objective of this paper is to present an innovative equipment for practical teaching in control engineering, paying special attention to its conceptualisation and its possibilities for the theoretical-practical training. The role of the control and automation issues applied to this prototype is discussed. A distributed control system (DCS) applied to this prototype and its possibilities will...
In distributed industrial control systems, functions of control units differ slightly although they seem to be identical. Functions change when hardware is replaced or when the function itself is upgraded. If the standard system is generated by merging the differences and is installed then to each control unit, control units become different with maintenance being carried out in each control unit...
The current situation in automation is characterised by an ongoing trend towards distributed systems based on intelligent devices, the application of Web services and the usage of Ethernet as the main communication media. The most important standard to deal with distributed control systems (DCSs) is the IEC 61499 whose industrial application is still at the beginning. Within this paper, a platform...
The application of distributed control systems is one of the main trends in current automation. Here, besides the programming of the control application code and its functional allocation to specific devices, an important point is the implementation of communication related code to exploit the underlying communication platform and realise the collaboration of the distributed control application code...
This paper describes formal modeling and verification of automation systems from the system engineering point of view. Reuse of model components is the key issue in order to bring the scientific modeling methodology into engineering practice. The reuse is achieved by the combination of modular modeling of automation systems with object-oriented description of models in UML style. This allows to benefit...
This paper describes the design and implementation of a CAN time-triggered based communication protocol named SCoCAN, (shared channel on CAN), intended for use in distributed control systems, as is the case of autonomous mobile robots. This protocol enables real time communication between different intelligent nodes (sensors, actuators and controllers). The SCoCAN protocol has been implemented in...
