A cyber-physical production system (CPPS) integrates capacities such as computing, storing and communication along with others in the physical world such as objects tracking and/or objects controlling. According to the Industrial Internet of Things (IIoT) concepts it is possible to infer that CPPS systems are normally connected to each other, and also connected to the virtual world of global digital...
Nowadays, the constantly changing market demands make modern automation systems offer more strict flexibility and efficiency requirements as energy efficiency, performance optimization and tolerance to process or controllers faults… The introduction of reconfiguration mechanisms within production automation systems allow meeting some of these requirements but, at the same time, they lead more complex...
Regarding current Oil&Gas production places, an important challenge is to deal with the increasing complexity of shop floor level data on existing production processes and, beyond that, allowing their possible vertical integration. In order to reach this goal, an integration of smart cyber-physical production systems (CPPS) into the automation production systems could be a solution. In the last...
Low Cost Automation promotes cost effective reference architectures and development approaches to increase flexibility and efficiency of production operations. This has led to the adoption of open networking standards for plant floor communications. OPC-UA may help industrial companies to become Industry 4.0 or Smart Manufacturing as it enables remote access to plant information, achieving thus horizontal...
Currently, factory automation systems need to cope with very different challenges, such as technological advances happening very fast, global and competitive market or product customization. These challenges lead to a new generation of automation systems based on the so-called Cyber-Physical Production Systems (CPPS) globally connected to form a flexible System of Cyber-Physical Production Systems...
The basis for the fourth industrial revolution is the availability of accessing all relevant information in real time by connecting all instances involved in the value chain. The ultimate goal is to manage the entire value chain process, improving efficiencies in the production process and coming up with better products and services. The essence of vertical networking comes from the use of cyber-physical...
New demands, coming from the industry 4.0 concept of the near future production systems have to be fulfilled in the coming years. Seamless integration of current technologies with new ones is mandatory. The concept of Cyber-Physical Production Systems (CPPS) is the core of the new control and automation distributed systems. However, it is necessary to provide the global production system with integrated...
The adoption of new technologies and automation standards, such as OPC-UA and IEC61499, is essential in order to satisfy the flexibility and reconfiguration needs required at the Factories of the Future. Currently, the Cyber-Physical Production Systems (CPPS) are at the core of the new control and automation distributed systems. However, it is necessary to provide the research community with low cost...
Video traffic is increasingly used in modern factory automation applications in order to improve the quality of the processes. However, since they require high bandwidth it may be difficult for critical applications to adapt dynamically to bandwidth requirements that may change in time, without affecting the performance of the overall applications, especially when they are time-sensitive. In this...
Cyber-Physical Systems (CPSs) are at the core of the future industrial control systems. Most industrial CPSs are usually implemented over expensive and domain-specific hardware platforms, such as industrial embedded control systems, mainly for safety and security reasons. In less-critical applications the use of open, low-cost hardware platforms that provide adequate computing capabilities, such as...
It is well known that modern factory automation applications must be able to adapt to changes in the production requirements. Since most manufacturing applications are distributed, it may be necessary to reconfigure several devices simultaneously. Unfortunately, dealing with reconfiguration is a complex issue for the developers of the applications, especially when applications are time-sensitive or...
Modern companies must be able to react in a timely way to changes in production and financial information since quick responses provide advantages against competition. As a matter of example, in automated trading systems a delay of 1 ms may be worth $1M. In addition, nowadays business decisions are made on the basis of increasing volumes of information, complicating the adoption of decisions on time...
Current complex industrial automation applications demand distribution, flexibility as well as adaptability to changes. On the other hand, the IEC 61499 standard specifically addresses this type of applications. It supports the definition of multidisciplinary views to independently define the functionality of the system from the hardware architecture. Notwithstanding this, although it was specifically...
Although a few industrial automation systems have also been implemented with DDS, this standard has not yet gained much significance in factory automation applications for several reasons. One of these reasons is that since DDS is aimed at a broad range of application domains and it may be necessary to provide certain guidelines in order to use it efficiently in factory automation applications by...
This paper describes the different communication patterns followed in industrial communications and maps them into DDS (Data Distribution Service) which is a recent middleware specification. This specification follows the publisher/subscriber paradigm and it is characterized by providing an API that allows tuning the QoS (Quality of Service) of the applications with a large set of parameters. This...
