Development of service oriented web-based SCADA application  [PDF]
Turc Traian,Gligor Adrian
Scientific Bulletin of the ''Petru Maior" University of T?rgu Mure? , 2011,
Abstract: This paper presents some considerations on the development and use of Web services in Web-based SCADA applications . SCADA systems are becoming more and more comon allowing the user to monitor and control local and remote technological processes. SCADA Web-based applications are SCADA applications for web clients, that run in web browsers. The use of Web services enables the development of web SCADA applications in a consistent way, by using the standardized methods for data transmission. Web services use XML standard for data transfer. This paper also proposes the use of the XML standard for describing virtual instruments.

Efficient Web-Based SCADA System  [PDF]

Computer Science , 2015,
Abstract: Computer-based supervisory control and data acquisition (SCADA) systems have evolved over the past four decades, from standalone, compartmentalized operations into networked architectures that communicate across large distances. There is an emerging trend comprising SCADA and conventional IT units toward consolidating some overlapping activities. This trend is motivated by cost savings achieved by consolidating disparate platforms, networks, software, and maintenance tools. For reasons of efficiency, maintenance, economics, data acquisition, control platforms have migrated from isolated in-plant networks using proprietary hardware and software to PC-based systems using standard software, network protocols, and the Internet. In this thesis, we present an approach for web-based SCADA systems that adapt to the behavior of the target application. In addition, we take into account the real time constraints that imposed by the nature of the problem. We show that our approach is more efficient than other approaches in terms of consuming as little as possible of the available resources (computational power and network bandwidth).
Simple, Flexible, and Interoperable SCADA System Based on Agent Technology  [PDF]
Hosny Abbas, Samir Shaheen, Mohammed Amin
Intelligent Control and Automation (ICA) , 2015, DOI: 10.4236/ica.2015.63018
Abstract: SCADA (Supervisory Control and Data Acquisition) is concerned with gathering process information from industrial control processes found in utilities such as power grids, water networks, transportation, manufacturing, etc., to provide the human operators with the required real-time access to industrial processes to be monitored and controlled either locally (on-site)or remotely (i.e., through Internet). Conventional solutions such as custom SCADA packages, custom communication protocols, and centralized architectures are no longer appropriate for engineering this type of systems because of their highly distribution and their uncertain continuously changing working environments. Multi-agent systems (MAS) appeared as a new architectural style for engineering complex and highly dynamic applications such as SCADA systems. In this paper, we propose an approach for simply developing flexible and interoperable SCADA systems based on the integration of MAS and OPC process protocol. The proposed SCADA system has the following advantages: 1) simple (easier to be implemented); 2) flexible (able to adapt to its environment dynamic changes); and 3) interoperable (relative to the underlying control systems, which belongs to diverse of vendors). The applicability of the proposed approach is demonstrated by a real case study example carried out in a paper mill.

An Architecture for “Web of Things” Using SOCKS Protocol Based IPv6/IPv4 Gatewaying for Heterogeneous Communication  [PDF]
P. Shrinivasan R. Patnaikuni, Raj B. Kulkarni
Advances in Internet of Things (AIT) , 2012, DOI: 10.4236/ait.2012.21002
Abstract: “Web of Things” evolved from “Internet of Things”. Lot of research has been done in designing architecture for “Web of Things”. Two main architectures are Smart gateway based architecture and embedded Web Server based architectture. These architectures address some of the basic and essential issues relating to Service Oriented Architecture for “Web of Things”. Taking into consideration the period of coexistence of IPv4 and IPv6 we propose an architecture using SOCKS protocol based IPv6/IPv4 gatewaying and refinements which facilitates smooth heterogeneous communications between the IPv6 and IPv4 enabled embedded nodes and can potentially be used to prevent security threats like Denial-of-Service (DoS) attacks on embedded devices attached to the web and increase its performance. Our architecture provides a way for caching responses from device and thereby increasing its efficiency and performance and yielding quick response times.

Abstract: To facilitate the exchange of plant data across platform and hierarchy, the OPC foundation has designed and released OPC XML-DA interface specification based on Web services. A middleware gateway is designed and implemented to XML-enable the existing OPC COM plant data and elevate OPC COM DA servers. The two different interfaces can parallel closely through such a middleware gateway.
CLOUD AND INTELLIGENT BASED SCADA TECHNOLOGY

Abstract: Burden placed on municipal utilities continues to increase. Customers demand quick identification of problem and solutions. Regulatory organizations have strict compliance requirements and an unprecedented ability to levy fines. The media is eager to sensationalize security incidents or weaknesses in public and natural resources. Traditional SCADA system, which comprises expensive architecture and manpower intensity, lack current needs. So in-order-to outperform these cons a contemporary approach is in need. This paper introduces a new cloud based SCADA technology. This matches with the contemporary needs and requirements. Uses open and proven IP technology. Completely eliminates many of the existing concerns and costs associated with small to medium-sized municipal and utility applications.

Abstract: As the rapid growth of Internet computing, it's critical to migrate Cobol-like legacy system to the distributed web platform. However, legacy systems usually use a character-based user-interface. It's different from web GUI not only in display style but also in interactive model. This paper implements amethod based on a stop and wait protocol to automatically migrate character user-interface to web. Our experience shows that it can increase the automation of this shifting process dramatically.
