Supervisory Control and Data Acquisition (SCADA) system monitors and controls industrial process in physical critical Infrastructures. It is thus of vital importance that any vulnerabilities of SCADA system must be identified and mitigated. DNP3 is and open SCADA network protocol that is mainly used in electrical utilities. However, the security mechanisms of DNP3 were neglected at its design s...

The vacuum control system of most of the CERN accelerators is based on Siemens PLCs and on PVSS SCADA. After the transition from the LHC commissioning phase to its regular operation, there has been a number of additions and improvements to the vacuum control system. They were driven by new technical requirements and by feedback from the accelerator operators and vacuum specialists. New control ...

At the operator level a new, PC-based SCADA system was introduced at the electrical substation of the Paks Nuclear Power Plant. An AI-based, intelligent advisory system was developed and connected to the SCADA system as knowledge server. The paper describes some of the advisory functions and their realizations in rules and procedures. Besides increasing reliability and safety of energy supply t...

Supervisory Control and Data Acquisition systems are basically Process Control Systems, designed to automate systems such as traffic control, power grid management, waste processing etc. Conventionally, SCADA is connected only in a limited private network because SCADA is considered a critical infrastructure, and connecting to the internet may put the society on jeopardy, SCADA operators hold b...

Modern Supervisory Control and Data Acquisition SCADA systems used by the electric utility industry to monitor and control electric power generation, transmission and distribution are recognized today as critical components of the electric power delivery infrastructure. SCADA systems are large, complex and incorporate increasing numbers of widely distributed components. The presence of a real t...

This paper describes a pair of virtual Supervisory Control and Data Acquisition (SCADA) systems. These virtual simulations were built using virtual devices that simulate industrial processes, emulate control system ladder logic functionality, utilize control system communication protocols, and implement industrial Human Machine Interfaces (HMI). The first of these focuses on a comprehensive vir...
