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 LEON with Linux operating system running over it, so both the hardware and IOS are open source. For prototyping the GR-XC3S-1500...
This paper presents the development and test of the standard IEC-60870-5 application layer protocol over TCP/IP 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 and IOS are open source.

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 language so a formal language is needed to describe its...
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 a performance report of them. After that, we analyze the...
In this paper we present an experimental setup for controlled RF radiation on small mammals. The main advantage of this setup is that the power absorbed by the animal can be directly measured through the external associated microwave circuitry. This same subsystem is used to control any possible spurious signal inside the enclosure and the power applied to the animal. The setup has been used to irradiate...
