This paper presents practical laboratories for teaching purpose in Supervisory Control and Data Acquisition (SCADA) systems. A SCADA system is described in terms of architecture, process interfaces, functionality, and application development facilities. These concepts are implemented on an integrated automation system, particularly for digital control of electric drives with a distributed perip...

The paper presents a Supervision, Control, Data Acquisition and Simulation (SCADA & Simulator) system that allows for real-time training in the actual operation of a modular PEM fuel cell system. This SCADA & Simulator system consists of a free software tool that operates in real time and simulates real situations like failures and breakdowns in the system. This developed SCADA & Simulator syst...

The four LHC experiments at CERN have decided to use a commercial SCADA (Supervisory Control And Data Acquisition) product for the supervision of their DCS (Detector Control System). The selected SCADA, which is used for the CMS DCS, is PVSS II from the company ETM. This SCADA has its own database, which is suitable for storing conventional controls data such as voltages, temperatures and press...

Current supervisory control and data acquisition (SCADA) systems do not have adequately tailored security solutions. Programmable logic controllers (PLCs) in SCADA systems are particularly vulnerable due to a lack of firmware auditing capabilities. Since a PLC is a field device that directly connects to a physical system for monitoring and control, a compromise of its firmware could have devast...

Supervisory control and data acquisition (SCADA) are applications that collect data from a system in order to automate the monitoring and controlling of its activities. Several industrial fields such as, electric utilities, water supplies and buildings’ facilities have already adopted SCADA systems to increase the efficiency and reduce cost. However, the IT community is concerned about the leve...

INTRODUCTION Interstate natural gas pipelines are operated using sophisticated supervisory control and data acquisition (SCADA) systems. These systems are used to monitor, control and analyze operations. Software which runs in conjunction with the basic SCADA system expands the usefulness of SCADA data to enhance reliability and efficiency of operations, improve customer service, and minimize u...

Supervisory Control And Data Acquisition (SCADA) systems have been widely used in industry applications. Due to their application specific nature, most SCADA systems are heavily tailored to their specific applications. For example, a remote terminal unit (RTU) that monitors and controls a production well in an oilfield is only connected with a few sensors at the well it resides. The RTU usually...

Electric power SCADA (Supervisory Control and Data Acquisition) system gradually transforming from a separate private network to an open public network, seriously increases the vulnerability risk in electric power SCADA. In order to assess the vulnerability risk in electric power SCADA system, the paper firstly uses Delphi method and AHP (Analytic Hierarchy Process) to build an index system of ...

In this paper we present a intrusion detection module capable of detecting malicious network traffic in a SCADA (Supervisory Control and Data Acquisition) system. Malicious data in a SCADA system disrupt its correct functioning and tamper with its normal operation. OCSVM (One-Class Support Vector Machine) is an intrusion detection mechanism that does not need any labeled data for training or an...

Supervisory Control and Data Acquisition (SCADA) systems support and control the operation of many critical infrastructures that our society depend on, such as power grids. Since SCADA systems become a target for cyber attacks and the potential impact of a successful attack could lead to disastrous consequences in the physical world, ensuring the security of these systems is of vital importance...
