Software design for the control system for Small-Size Telescopes with single-mirror of the Cherenkov Telescope Array
The Small-Size Telescope with single-mirror (SST-1M) is a 4 m Davies-Cotton
telescope and is among the proposed telescope designs for the Cherenkov
Telescope Array (CTA). It is conceived to provide the high-energy ( few TeV)
coverage. The SST-1M contains proven technology for the telescope structure and
innovative electronics and photosensors for the camera. Its design is meant to
be simple, low-budget and easy-to-build industrially.
Each device subsystem of an SST-1M telescope is made visible to CTA through a
dedicated industrial standard server. The software is being developed in
collaboration with the CTA Medium-Size Telescopes to ensure compatibility and
uniformity of the array control. Early operations of the SST-1M prototype will
be performed with a subset of the CTA central array control system based on the
Alma Common Software (ACS). The triggered event data are time stamped,
formatted and finally transmitted to the CTA data acquisition.
The software system developed to control the devices of an SST-1M telescope
is described, as well as the interface between the telescope abstraction to the
CTA central control and the data acquisition system.Comment: In Proceedings of the 34th International Cosmic Ray Conference

The Joint COntrols Project Framework
The Framework is one of the subprojects of the Joint COntrols Project (JCOP),
which is collaboration between the four LHC experiments and CERN. By sharing
development, this will reduce the overall effort required to build and maintain
the experiment control systems. As such, the main aim of the Framework is to
deliver a common set of software components, tools and guidelines that can be
used by the four LHC experiments to build their control systems. Although
commercial components are used wherever possible, further added value is
obtained by customisation for HEP-specific applications. The supervisory layer
of the Framework is based on the SCADA tool PVSS, which was selected after a
detailed evaluation. This is integrated with the front-end layer via both OPC
(OLE for Process Control), an industrial standard, and the CERN-developed DIM
(Distributed Information Management System) protocol. Several components are
already in production and being used by running fixed-target experiments at
CERN as well as for the LHC experiment test beams. The paper will give an
overview of the key concepts behind the project as well as the state of the
current development and future plans.Comment: Paper from the 2003 Computing in High Energy and Nuclear Physics

OPC Protocol Application for Real-Time Carbon Monitoring System for Industrial Environment
Global warming is referred to the rise in average surface temperatures on earth primarily due to the Greenhouse Gases (GHG) emissions such as Carbon Dioxide (CO2). Monitoring the emissions, either direct or indirect from the industrial processes, is important to control or to minimize their impact on the environment. Most of the existing environmental monitoring system is being designed and developed for normal environment monitoring. Hence, the aim of this project is to develop industrial CO2 emission monitoring system which implements industrial Open Platform Communications (OPC) protocol in an embedded microcontroller. The software algorithm based on OPC data format has been designed and programmed into the Arduino microcontroller to interface the sensor data to any existing industrial OPC compliant Supervisory Control and Data Acquisition (SCADA) system. The system has been successfully tested in a lab with the suitable environment for real-time CO2 emissions measurement. The real-time measurement data has been shown in an industrial SCADA application which indicates successful implementation of the OPC communications protocol
Implementation of Service Orchestrated control procedures in OPC UA for JGrafchart
The automation industry is facing many challenges with higher demands on their production process. Technology used today does not allow for fast changes in the production line. This thesis will investigate how services can be modelled using a new standard OPC UA for data exchange. Encapsulation of the mechatronic functions as services will allow for creating control software using a SOA approach. An experimental set-up will investigate how an OPC UA server and client are created
Industrial agents in the era of service-oriented architectures and cloudbased industrial infrastructures
The umbrella paradigm underpinning novel collaborative industrial systems is to consider the set of
intelligent system units as a conglomerate of distributed, autonomous, intelligent, proactive, fault-tolerant,
and reusable units, which operate as a set of cooperating entities (Colombo and Karnouskos,
2009). These entities are forming an evolvable infrastructure, entering and/or going out (plug-in/plugout)
in an asynchronous manner. Moreover, these entities, having each of them their own functionalities,
data, and associated information are now connected and able to interact. They are capable of
working in a proactive manner, initiating collaborative actions and dynamically interacting with each
other in order to achieve both local and global objectives.info:eu-repo/semantics/publishedVersio
Interoperability between OPC UA and oneM2M
AbstractA key requirement of realizing the connected world featured by IoT is to ensure interoperability among different connected devices. Interoperability is also at the basis of the realization of the novel vision of Industry 4.0; a lot effort is put to make interoperable the interchange of information between industrial applications, also including IoT ecosystems. For this reason, during these last years, several approaches aimed to enhance interoperability between industrial applications and IoT appeared in the literature. In this paper an interoperability proposal is presented. It is based on the idea to realize interworking between the two standards considered among the reference ones in the industrial and IoT domains. They are the OPC UA for the industrial domain and oneM2M for the IoT. Interworking is realized in such a way to allow industrial applications based on OPC UA to acquire information coming from oneM2M-based IoT devices. The proposal allows an OPC UA Server to publish each piece of information produced by oneM2M-based IoT devices, so that this information may be consumed by industrial applications playing the OPC UA Client role
