Recent studies show the designs of automated systems are becoming increasingly complex to meet the global competitive market. Additionally, organizations have focused on policies to achieve people's safety and health, environmental management system, and controlling of risks, based on standards. In this context, any industrial system in the event of a fault that is not diagnosed and treated correctly could be considered to pose a serious risk to people's health, to the environment and to the industrial equipment. According to experts, the concept of Safety Instrumented Systems (SIS) is a practical solution to these types of issues. They strongly recommend layers for risk reduction based on control systems organized hierarchically in order to manage risks, preventing or mitigating faults, or to bringing the process to a safe state. Additionally, the concept of Risk and Hazard Control can be applied to accomplish the required functionalities. It is based on problem solving components and considers a cooperative way to find a control solution. In this context, the software architecture can be based on a service-oriented architecture (SOA) approach. This paper initially proposes a new architecture for design of safety control systems for critical systems, based on Safety Supervisory Control Architecture, in accordance with standards IEC 61508 and IEC 61511. Furthermore, a method is also proposed for design the control layer of risk prevention within Safety Supervisory Control Architecture.

“…The introduction of EXI encoding for DPWS and OPC UA will provide substantial improvements in compactness and processing efficiency and hence lowering the hardware requirements for the legacy systems integration approach presented in [14]. In this way, the proposed SOA gateways that expose the legacy systems functionality as services can be less powerful and put closer to the systems they wrap.…”

Integration of legacy systems is also covered and is essentially extension to the SOA for devices system presented in [14] while taking the EXI into account.…”

Abstract-The advent of Service-Oriented Architecture (SOA) in the automation domain has made possible the cross-layer vertical integration of devices, manufacturing systems and business processes. However, the use of standard web service technologies is not always possible in an industrial environment with high real-time requirements and limited hardware resources due to the overhead connected to XML processing. The work presented in this paper analyses the opportunities, advantages and challenges when applying the newly emerged Efficient XML Interchange (EXI) standard for XML encoding to the factory automation systems. The two major SOA-based automation middleware architectures, namely OPC Unified Architecture (OPC UA) and Devices Profile for Web Services (DPWS), were investigated. Furthermore, we present an EXI-based approach for extending the reach of the service technology covering deployments on resource constrained embedded devices.

The new control paradigm Internet of Things (IoT) in intralogistics propagates highly modular and flexible decentralized control systems based on agent technology and radio-frequency identification (RFID). The productive application of such systems demands the fulfillment of several requirements, which exist in the industrial reality of the facility logistics. The real-time requirements in decentralized control systems are examined within the scope of the Collaborative Research Center (CRC 696) "Logistics on Demand" (sub-project C5 -"Real-Time Logistics"). The systematic performance analysis of legacy and new controls is an important aspect of this research work. In this paper an approach for the evaluation of the performance of decentralized control is proposed. The collection and analysis of performance data is facilitated by self-developed measuring instruments. IntroductionRecently applied research in the field automated material handling shows a strong inclination to developing decentralized control concepts (see [Win08], [HLS06] and [Wil06]). Improved scalability and adaptability as well as the reusability of system components (see [Lor03], [BSc01]) are often mentioned as the system advantages to be expected. Here increased profitability is to be guaranteed by shorter start-up periods and low effort expandability (see [GCK08]). However there is a gap between the vision of a desired decentralized material flow control and the realization of this vision in industrial practice. The use for performance evaluation instruments, proposed in this paper, helps to close this gap. Internet of Things in IntralogisticsThe control paradigm Internet of Things in intralogistics (see [GtH10]) propagates a decentralized approach to control material handling systems. The transported goods themselves take over the control and use the transport capability as well as other capabilities of the material handling plant. Modern technologies like radio-frequency identification (RFID) are used, having relevant information for transportation on the RFID-tag of the corresponding transportation good. A possibility to realize such distributed control systems is the usage of software-agents. The control system examined in this work is a multi-agent-system, where unit load agents are negotiating with each other and with conveyor agents to get access to plant resources. The concept provides for the distribution of control hardware and software along the mechanical components of a conveyor plant. This distribution is meant to produce a high modularity of the control. However, this makes additional demands to real-time capability and the performance of responsible control components. Real-Time Problems and Control Performance as a Research TopicThe real-time capability of material flow control is an important requirement which is in contrast to the decentralized control principle (see [HLL07],[Ste03]). The reason for this confrontation lies in the nature of distributed systems with decentralized data management and processing. In these system...
