The traditional students’ evaluation method is a process designed to evaluate the qualitative aspects but, in fact, its final result is a grade that values the quantitative aspect. The challenge of this work is to consider a modifying, dynamic and coherent method of evaluation in the industrial automation area. Especially in the academic area, online laboratories are a commonly used distance learning model where the student practices the theoretical knowledge using a fieldbus simulator. These practical sessions can be performed in any location, as long as an authenticated, secure access is provided. At the Sao Carlos Engineering School, University of Sao Paulo (EESC/USP), a FOUNDATION FieldbusTM simulator named FBSIMU (Function Block Simulator) is being used as on online laboratory (Mossin, 2007). Engineering students can get involved with automation system technologies, as well as control theory, by implementing an application, therefore being able to explore and practice their knowledge. Considering the training and learning environment, it is important to implement a robust evaluation system to help teachers in the industrial automation area identifying students’ strong and weak points. The traditional evaluation method is a process designed to evaluate the qualitative aspects but, in fact, its final result is a grade that values the quantitative aspect (Rosa, 1999). Our challenge is to consider a modifying, dynamic and coherent method of evaluation. A graduated student in Automation must know the technologies related to programmable controllers, computer networks and manufacture automation. Besides these technologies, the student must also know how to configure and specify industrial communication systems, supervise instrumentation and control projects, identify control strategies in industrial processes, tune and optimize control loops in industrial processes, etc. Furthermore, there is a large amount of industrial protocols (FOUNDATION FieldbusTM HSE, FOUNDATION FieldbusTM H1, HART, PROFIBUS, DeviceNet, among others) available in the market and each one of those requires different particularities from the student. If we look at the traditional teaching method, even an excellent student in a certain area could fail the course and miss great opportunities for not having the formal education the teacher was ideally expecting. Regarding the inadequacy of the traditional method, this paper proposes the use of the fuzzy set technique that will be applied in the evaluation process of the industrial

One of the most important packet timing protocol for next generation networks is Precision Time Protocol (PTP) defined by IEEE1588 standards for PTP version 2 (IEEE1588-2008) and PTP version 2.1 (IEEE1588-2019), respectively. The PTP is considered a step forward in comparison to other packeting timing protocol such as NTP and provides highly accurate time. Depending upon implementation, a time accuracy of 100 ns to sub-microsecond is attainable. In addition, PTP version 2.1 also supports internal and external security features making it ideal time synchronization protocol for next generation networks for different industry verticals such as 5G based Telecom network infrastructure, Smart Grid, Financial Network Services, Industrial, CATV, and Broadcast network infrastructure. This chapter explores details on PTP including its methods of operation, transport mechanisms, message structure, security features, and various profiles for use in different industry-specific networks environment.

Synchronization of industrial network is critical to proper operation of factory automation and industrial control system. Improper synchronization may cause catastrophic failure in plat operation. The industrial networks consist of Industrial Ethernet and Fieldbus communications technologies. No single communication technology of Industrial Ethernet and Fieldbus provides complete solutions for industrial operation and hence, an industrial network may compose of multiple of these communications technologies. Each of these technologies also implements two key elements of network communications: deterministic network and real-time control. As for real-time control, synchronization of clock may vary depending upon underlying protocol(s) in use in the industrial network. Some of these technologies use proprietary time synchronization mechanisms while others use standard base technology such as PTP for precision time synchronization.

This paper proposes a gateway based on EtherCAT and DeviceNet for a smart factory. EtherCAT is chosen as the primary protocol and DeviceNet is used as secondary protocol. Due to its outstanding features, the gateway can support many devices and increase the quality of service (QoS) of the network. With proposal gateway, an embedded programmable logic controller (ePLC) can replace the hardware programmable logic controller. The gateway was implemented with an ARM-Cortex M3 and TwinCAT3 was used as the ePLC. Experiments show that this gateway provides a high QoS and also satisfies the real-time requirements of a factory system.

The development of DeviceNet communication drivers and their electronic data sheets (EDS) for configuring them in automation software applications are proposed. In this regard, Common Industrial Protocol (CIP) Standard established by ODVA is reviewed, and a commercial DeviceNet network is analyzed in order to define hardware and software requirements for implementing the proposed drivers. Then, prototypes for discrete as well as analog sensors are implemented; their EDS files are developed too. After, the implemented drivers are integrated in a commercial DeviceNet network for validating their performance by monitoring their operation through RSNetWorx for DeviceNet. The developed prototypes and their EDS files shown a proper operation according to proposed aims. Therefore, by this work, the basis for the development of DeviceNet communication drivers for sensors were established.

Aiming at the problems of low control precision and complex control process in electrical engineering automation control, this paper proposes a kind of intelligent electrical engineering automation control technology based on DeviceNet. This paper focuses on the development process, communication protocol and object modeling method of DeviceNet universal I / O interface based on microprocessor. At the same time, this paper designs the application layer software, and gives the detailed hardware circuit and software design process. The experimental results show that the method can reduce the complexity of the control process and improve the control accuracy.

DeviceNet is an object oriented application networking solution for automation. It’s most important advantage is reduction of hardwiring and the corresponding high cost required for the industrial devices. The protocol is used to form a closed, controlled and a networked system. The hardwired circuit uses a number of relays that needs to be monitored continuously at the time of welding. The CAN protocol used for communication acts as a base for DeviceNet. The parameters like temperature, voltage and current are controlled using the communication. This eliminates human interference and ultimately improves efficiency of the welding job to be done. An integrated approach to automate the time consuming process is described in this paper.

Security is a vital aspect of industrial control systems since they are used in critical infrastructures and manufacturing processes. As demonstrated by the increasing number of emerging exploits, securing such systems is still a challenge as the employed fieldbus technologies do not offer intrinsic support for basic security objectives. In this work we discuss some security aspects of DeviceNet, a communication protocol widely used for control applications especially in the North American industrial sector. Having the Controller Area Network (CAN) protocol at its base, DeviceNet inherits all the vulnerabilities that were already illustrated on CAN in-vehicle communication. We discuss how the lack of security in DeviceNet can be exploited and point on the fact that these vulnerabilities can be modelled by existing formal verification tools and countermeasures can be put in place.

Controller Area Network (CAN) is the most used protocol for intra-vehicle communication between Electronic Control Units (ECUs) for decades. Moreover, there are several implementations of industrial networks built on top of CAN, (i.e. CANopen and DeviceNet) that expanded even more its area of application to almost any industrial automation field. The growing needs for data in today’s modern and safe applications led to CAN Flexible Data Rate (CAN FD) in order to increase the network throughput and pushed the data field of the CAN frames beyond the 1Mbps limit of the high speed CAN chips. A low cost CAN-USB interface application for dual CAN bus network monitoring, diagnose and maintenance is proposed which can be easily ported on any member of the ARM Cortex-M microcontroller family with built-in CAN or CAN-FD communication.

Common application layers are the key to advanced communication and true network integration. ODVA's four best-in-class networks—EtherNet/IP, DeviceNet, ControlNet, and CompoNet—all are linked by one of the industrial automation's most versatile protocols: the Common Industrial Protocol, known as CIP. CIP encompasses a comprehensive suite of messages and services for the collection of industrial automation applications—control, safety, energy, synchronization and motion, information, and network management. CIP allows users to integrate these applications with enterprise-level Ethernet networks and the Internet. IP allows users to benefit today from the many advantages of open networks and protects their existing automation investments, while providing an extensible and upgradable communication architecture. As a single, media-independent platform that is shared by a variety of networking technologies, CIP provides the interoperability and interchangeability that is essential to open networks and open systems. The Base Energy Object acts as an Energy Supervisor for energy implementations in CIP.

This paper addresses the applicability of using DeviceNet — an industrial network — to optimize Solar PV Systems. The design permits accurate and reliable monitoring, feedback, and controlling of every PV solar related device to detect the faulted, cracked, or malfunctioning panel. DeviceNet does not only handles I/O monitoring, diagnostics, Panel tracking, etc. but it also can power up certain devices without extra power sources or wires. This system is capable to communicate to several PLCs and HMIs that can be used as advanced SCADAs. This paper, considers a reliable industrial networking — DeviceNet and perspectives to achieve a smart green system for a specific PV area with minimum cost and lowest energy consumption that is self-powered by the solar system itself.

For the four kinds of network protocols which are common in industry :PROFIBUS-DP, DeviceNet, EtherNet/IP and Modbus-RTU, a gateway has been designed which could integrate the four protocols ,and have developed hardware and software program of the Multi-protocol self-adaptation gateway .It uses STM32F407ZGT6 as its major chip. A Modbus-RTU interface has been designed which depends on the UART interface of the main chip to send and receive packets in hardware. It use COMX as hardware interface of PROFIBUS-DP ,DeviceNet ,and EtherNet/IP to process their packets. It has achieved a function that the PROFIBUS-DP interface will change its address with the changing of the configuration of master .In addition, the multi-protocol self-adaptation gateway can integrate several masters which support different protocols in one network. The master controllers could communicate with each other in this network.After being tested and verified ,it has been used in the communication of DCS systems, and it has converted the packets of the four protocols which have been mentioned above and it has met the demands of designing a gateway.

The Feedback control system connected to a real time network through which the control process takes place are called network control system(NCSs).Features of NCS is the information like reference input, plant output, control input is exchanged between sensors, controllers, actuator using a network like CAN bus. The system wiring is reduced, easy to maintain and increases the system reliability. In the conventional control theories uses some ideal assumptions like equal distance sensing, synchronized control and non-delayed sensing and actuation. But in time varying systems this assumption fails due to transmission delay or packet dropout. In this paper Stability of NCS is analysed by considering transmission delay for a computer controlled system using scheduling algorithm The In direct digital control systems, computerized control replaced all analog instrumentation for the process control. Example system is shown in the figure 1 with a summary of several modular manufacturing system integrated control networks like FireWire, DeviceNet and Ethernet. In the example system, FireWire are used for the job requires high data throughput and high bandwidth. DeviceNet are used for the jobs which require low bandwidth like short, periodic messages signals transmission. Ethernet is preferred for the job like information exchange between the upper supervisory workstation and the controller is high volume but not time critical. Sensors with analog outputs and actuators with analog inputs are point to point connection with the digital computers. Sensing, actuating and control signal are deadline based since speed of all digital control CNC machines are high due to accuracy of the product manufacture in the system. Some of the constraints in the design of the system which affects the performance is choosing good scheduling algorithm, either constant or time varying network induced delay between the sensor to controller and controller to actuator in the shared medium, unreliable transmission path, packet dropouts due to packet size, bandwidth and busy path. Depending on the systems environmental condition while analysing some parameter are kept constant. Fundamental issues like time varying transmission period, network scheduling, network induced delay, single packet or multiple packet transmission of plant inputs and output and dropping of the network packets are basic problems in NCSs. In this paper we have considered time delay factor as variable since message transmitted between devices are either control data, which is time critical or information data which only needs guaranteed delivery.

At present, the interface system in IC equipment control software system has to be changed even when a small hardware change occurs, which increases the time and cost of system debugging. This is one of the technical problems needed to be solved in course of development of IC equipment control system software.Therefore, the characteristics of the semiconductor device in IC equipment which used the DeviceNet has been analyzed in this paper. Then one DeviceNet-Oriented interface system, which is capable of shielding the difference of the details of the hardware, has been designed and developed.

The design and construction of a diagnostic device requires the development of a system for the acquisition and processing of measurement data, numerous cable connections and an on-board computer. The key component of a diagnostic system was the Fujitsu FUTRO S100 on-board computer in shock and vibration-proof housing, with passive cooling and a 16 GB Compact Flash memory card. The computer was provided with a NVOX LCD 10” VGA/FVAT touch screen. The following software was used: Windows XP-2000, USB/DeviceNet interface module and a diagnostic program. The computer was connected to the I-7565USB/DeviceNet master device via the USB port. The CAN bus connected the interface module with three slave devices collecting data from sensors installed in various locations of a wheeled tractor.

The DCS (Distributed Control System) have made a great impact on the process industries like manufacturing, refinery, textile allowing automatic industrial processes with multiple input–output arrangements in real time. The above applications and its better performance indirectly depends on the communication between devices, control stations where sharing of network for optimal communication is most important. The present paper deals with study of communication parameters which decide the performance of the network in network control system (NCS). The model developed is a network of nodes explains the time delay analysis of token passing in ControlNet and DeviceNet to get the performance of the NCS. Simulation of the model for 4 nodes using token passing protocol among DeviceNet for NCS has been simulated and analyzed.

Las redes industriales para automatización han experimentado un gran auge en los últimos años y DeviceNet es uno de los protocolos con mayor popularidad. En una red DeviceNet se identifican dispositivos esclavos, por lo general sensores y actuadores, y al menos, un dispositivo escáner encargado de configurar y administrar las transacciones en la red. El escáner debe comunicarse directamente con los dispositivos de la red DeviceNet y entregar la información recolectada a un dispositivo de mayor nivel jerárquico como un PLC o un PC. Aunque existen especificaciones y recomendaciones para elaborar un dispositivo esclavo DeviceNet, no hay una pauta clara de cómo implementar el maestro o escáner DeviceNet, ni tampoco para diseñar el enlace de comunicación entre el escáner y el equipo de control. En este artículo, se presenta un esquema de comunicación diseñado especialmente para soportar el intercambio de datos entre un escáner DeviceNet y una aplicación software residente en un PC.

Referred to the protocol specification of DeviceNet, the hardware structure was set up by analysis of the physical layer and data link layer. Then it emphasized the software implementation procedure of the communication between master and slave from the view of application layer. With the software and hardware design method, a group 2 only communication node based on DeviceNet was designed through the platform of CAN controller SJA1000. Finally both IXXAT Corporation’s DNSDT protocol analysis software and RockWell’s master device were used to test the slave node. And the experimental data is detailed to verify that this slave node can fully meet the requirements specification of DeviceNet.

Firstly applied PIC18F458 single chip as control chip in hardware design and proposed the power source, dial switch and LED interface circuit design scheme based on DeviceNet protocol specification. Secondly proposed the soft design scheme, included established module and I/O information communication. At last SST-DN3-PCU-1 main station card was 阿applied as network analyzer to analyze the communication data detail.

This paper reports a feasibility analysis of the use of a hybrid control network based on the Common Industrial Protocol (CIP). For this feasibility analysis, the message service time between DeviceNet and the wireless devices is investigated. The feasibility of hybrid control networks is analyzed using a mathematical analysis and experimental tests. The experimental results show the feasibility of the hybrid control networks in terms of the polling/COS service time and the average end-to-end delays.

Since the 1990s, the increasing deployments of networked automation systems led to increased manufacturing productivity, improved interchangeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and maintenance costs. However, the reliability of a network has great impact on the reliability of a networked automation system. This paper presents a novel network reliability assessment method that provides diagnostic and prognostic information for DeviceNet. This work proposes a hybrid network error analysis method using combined physical and datalink layer features to provide complete communication log information. Furthermore, a network/node time to failure (bus-off) prediction algorithm was developed based on the analysis of the patterns of the interrupted packets on the network. The method developed in this study can be used for network reliability evaluation and diagnosis, facilitating better network maintenance decision making. A laboratory testbed was constructed and the experiments on network and node time to failure were conducted to demonstrate the concept. Experimental results show that the proposed method can fully reconstruct the communication log, and predict the network/node bus-off time successfully. Copyright © 2010 John Wiley & Sons, Ltd.

Since the 1980s, the manufacturing environment has seen the introduction of numerous sensor/actuator bus and network protocols for automation systems, which led to increased manufacturing productivity, improved inter- changeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and maintenance costs. However, such heightened manufacturing integration facilitated by industrial networks also leads to dramatic consequences of improper or degraded network operation. This paper presents a novel Network Health Management system that provides diagnostic and prognostic information for DeviceNet at the device and network level. It extracts features from analog waveform communication signals, as well as logic and timing features from digital packet logs. These features are used to evaluate the network system performance degradation by applying multidimensional clustering techniques. In addition, this work proposes a hybrid prognostics structure using combined physical and logic layer features to provide fault location information that cannot easily be realized with analog or digital data independently. Furthermore, an intermittent connection diagnostic algorithm which analyzes patterns of interrupted and error packets on the network was developed. This tool can be used as a packet source identification method which uses joint analog features and digital information inferred from analog waveforms. A test-bed was constructed and the experiments of network impedance mismatch, cable degradation, and intermittent connections were conducted in laboratory environment. Experimental results show that the proposed system can detect degradations of the network and identify the location of the intermittent connection successfully. Field tests performed in an industrial environment were also conducted and their results are discussed.

Due to the advent of smart field devices in industrial automation, information on these devices can permeate throughout the plant and business management. With different protocols to connect the fieldbus protocols such as DeviceNet, ControlNet, and PROFIBUS to the Internet, there is no common platform to develop applications for these fieldbus protocols. This paper presents an OPC connectivity-based approach to remote monitoring and control. The proposed approach is integrated services to access real-time and history data from distributed control systems (DCSs) with the utilization of the OPC technology and XML to enterprise applications. The experimental results are presented, indicating that the performance of the proposed system is feasible for deploying to real automation system applications.

The next time you visit the theatre, the scenery and performers you see flying from wing to wing may be under the control of a technology that started life a few years ago in the manufacturing and process industries. The author raises the curtain on theatrical automation. The theatre production of Peter Pan is propelled by Profinet. This technology, which wows the crowds by making theatre performers soar across the stage, is the open Industrial Ethernet standard for distributed automation systems, developed by Siemens and the Profibus User Organisation. Using existing IT standards such as TCP/IP, XML and OPC, and built on the IEEE 802.3 collection of wired Ethernet standards, it enables the integration (via a proxy) of existing fieldbus systems such as Profibus, DeviceNet, and Interbus, without the need to change existing devices.

Monitoring the dark noise of photomultiplier tubes (PMT) is important for maintaining the operation of the Borexino detector. For this purpose, a dark noise monitoring system was developed on the basis of the CAN network and the DeviceNet upper-level protocol. The system consists of a set of CAN controllers, which digitize PMT signals and transmit data over the CAN to the host computer. The software creates a DeviceNet protocol stack, ensuring data collection and transmission. The user interface is built on the basis of dynamic WEB pages.
