There are major discussions about the vulnerability of protocols based on real-time Ethernet (RTE) and techniques for detecting anomalies. Thus, this work proposes a methodology anomalies by optimizing data extraction classifying traffic-related features. In order to cope with proposal, an artificial neural network (ANN)-based classifier is trained using selected relevant These features extracted variable sized sliding window according their correlation other expected output classifier. The...

With the new concepts brought by Industry 4.0 and Internet of Things (IoT), it is expected more equipment communicating with each other, using local cloud computing servers. In order to communication between devices be efficient, fast time deterministic, necessary choose a suitable network protocol. this context, article presents performance comparison quantity used data spent send receive messages in two well-known protocols field IoT Industrial loT (IIoT): MQTT OPC UA. The obtained values...

Currently, in a scenario of Industry 4.0, the communication protocol is key factor success for modern industry. Allits needs could be fulfilled by Ethernet based protocols. One most used protocols PROFINET{concerning number applications growth last years, being one promising future. Considering its importance, this paper discusses panorama which characterize current protocol. To achieve main goals, 92 studies were considered data extraction. The obtained results relevant to provide area, as...

The use of industrial communication protocols based on Real-Time Ethernet (RTE) standards is completely replacing traditional fieldbuses. As usual, when a technology becomes mature, the need efficient diagnostic and maintenance tools quickly raises. Very often, following paradigm Industry 4.0, most effective systems are today distributed, cloud-centric, architectures artificial intelligence. However, distributed analysis RTE challenging, considering plurality stringent cost constrains which...

This study evaluates a large Profinet network using ring topology applied in an industry production line. The analysis is based on some performance indicators: jitter and throughput taking consideration the update time of devices, number switches cable length between IO-Devices IO-Controller. studied has considerable amount devices including distributed IOs, sensors actuators. Its setup provides star line topologies, besides manage switches. results show operation MRP protocol achieved...

Abstract Electric motors are widely used in the industry. Several studies have proposed methods to detect anomalies their operation, but always using sensors dedicated this purpose. In sense, work aims fill gaps related works presenting a method for detection of faults rotating machines driven by electric motion control applications PROFINET network and PROFIdrive profile. The does not require any additional or provide data diagnostic system. Instead, methodology is based on analysis...

Intelligent fault diagnosis systems of equipment are essential in industries, to prevent failures, reduce downtime and increase plant availability. In this context, work proposes a methodology develop diagnostic for detecting anomalies identifying failures the piping system due malfunctioning pumps, such as cavitation. Relevant information is extracted based on motor electric current, available PROFINET networks by smart relays, widely used type application. A prototype hydraulic was created...

PROFINET networks are increasingly being applied in industrial environments. Due to its expansion, it is common for new diagnostic tools emerge dedicated protocol. Being more specific, would be of the most importance if, by means network traffic analysis, was possible identify network's operating status (normal operation or with some anomaly) automatically. In view facts, this article aims propose a methodology classifying events related through feature extraction and classification...

The number of breweries in Brazil has been rapidly increasing recent years, especially with the creation new microbreweries, which are typically small and medium-sized companies that focus on product innovation but still have a manual production process. In this context, work aims to identify profile these Brazilian market, understanding their main KPIs level automation. From point, it suggests an architecture for digital transformation, provides transparency operation industrial process...

Industrial communication networks are a fundamental aspect of the connectivity demanded by Industry 4.0. In this scenario, protocols based on Real-Time Ethernet, which have been proven for automation tasks in past, may be suitable also new projects. Since 4.0 requires additional features never exploited before control that could jeopardize real-time, trustful evaluation key performance indicators is mandatory. As known previous works, collecting and analyzing Ethernet data challenging, not...

Industrial communication protocols are a key factor on Industry 4.0. The big amount of data, the ability to prevent failures and deal with them in friendly interface is priceless. But most players protocol chain not well prepared for system installation, commissioning diagnose time. Since network scenario industrial application has been stratified (by different technologies by successive installations), lack knowledge at lower levels could cause impact performance 4.0 services. In this...
