Este artículo versa sobre una aplicación, denominada Digital Systems Studio (DSS), desarrollada en el contexto de un proyecto de fin de carrera de Ingeniería en Informática, dirigido por la profesora Gemma Sánchez Antón [1]. Dicha aplicación es una herramienta de CAD para el diseño, comprobación y simulación en el tiempo de sistemas digitales....

When teaching computer networks as part of a Computer Engineering degree, emphasis is placed on higher-layer protocols while Physical and Data-Link layers usually play a secondary role. Physical aspects of data communication are sometimes taught as an independent, not-related, topic whereas Data-Link concepts are "hard" to our students. We...

At present, in our project we are researching about the viability of the enhancement of the basic telecontrol information supplied by SCADA systems by adding multimedia content. SIP is a simple and light protocol, with client-server architecture, which allows to achieve voice and video communications through a data IP network, in similar way as...

Este artículo presenta un trabajo práctico para el estudio del nivel físico de la transmisión de datos siguiendo las nuevas metodologías propugnadas por el nuevo Espacio Europeo de Educación Superior en el marco de la convergencia universitaria europea. La base del trabajo que se propone a los alumnos consiste en estudiar el problema de la...

The telecommunication networks of telecontrol systems in electric utilities have undergone an innovation process. This has removed many of their technical restrictions and made it possible to consider carrying out telecontrol tasks with general standard protocols instead of the specific ones that are used currently. These are defined in the...

This paper presents some works made in the development of communications software for an embedded open core system. By using a Linux-based processor implemented on a FPGA, we are developing the appropriate software in order to implement a remote unit to be used in a telecontrol network. We present an analysis of the physical devices needed and...

This paper presents the development and test of the standard IEC-60870-5 application layer protocol for a Remote Terminal Unit (RTU) based on open hardware and software. The RTU hardware is an embedded system, a SoC-type design using FPGA that has been programmed with the open core LEO. with Linux operating system running over it, so both the...

This paper presents an open source implementation for a data-link layer protocol specified in IEC 60870, protocol specification for telecontrol networks. It has been tested over LEON an embedded system with a Linux based operating system. Protocol engineering methods have been used in order to implement the protocol. The standard is in natural...
