Technologies for SOA-based distributed large scale process monitoring and control systems

Abstract

In a SOA-based system the applications are organized in a manner such that interoperable services can be used from different domains. In a process industry context, different domains can refer to, for example, process instrumentation and monitoring, execution of process control, data acquisition, etc. Large process industry systems are a complex and potentially very large sets of multidisciplinary , heterogeneous, networked distributed systems. Current industrial process control systems are typically vendor specific; in addition the different domains are associated with different layers, different standards and different technologies. In the paper the authors report about the investigations and assessments performed to find answers for four major critical questions that arise as key when technologies have to be selected and used in a true Service Oriented Architecture (SOA) based distributed large scale Process Monitoring and Control system: (1) Real-time SOA (what are the limits of bringing SOA into high performance control loops?); (2) Management of large scale industrial distributed control systems (is it feasible to manage up to tens of thousands of service-oriented devices?); (3) Distributed event-based systems are asynchronous (what are the limits compared to traditional periodic scanning systems?) and (4) Service specification (which semantics are the most suitable for specifying process control and monitoring services?).

Organizing IoT Systems-of-Systems from standardized engineering data

“…For the transfer of the ISA-95 architecture to a cloud based approach much important work is already published, including: system architectures [3], [4]; suitable technologies [5]; real time considerations [6], [7]; migration from legacy systems [8], [9] and engineering for cloud based automation [10], [11]. This cross-compliance is depicted on Fig.…”

Concepts and architecture for a thumb-sized smart IoT ultrasound measurement system

“…The area of integrating IoT's to a System of Systems is still in an early phase of research. Architecture and technology investigations can be found in [38], [39]. Work extending these including technology implementations has been released as the open source Arrowhead Framework [1], [52].…”

“…To further enhance interoperability between IoT devices, a considerable amount of work is aimed at the use of serviceoriented architecture, SOA [1], [38], [39]. Here, SOA protocols, encoding, compression and semantics can be integrated to provide the possibility of interoperability at the service level.…”

Schedule-based service choreographies for real-time control loops

“…In both domains the result is a hardware architecture of multiple networked processing units. The pressure to innovate is now focused on software where development approaches are shifting to model-driven [4] or service-oriented [5] methodologies. Both approaches mandate decomposing an embedded application into a set of interdependent tasks.…”
