Time-Sensitive Networking : A Milestone for Industry

An important development: In the future, everything will build on Ethernet with TSN and can be operated in parallel as required. (siemens)

The proven communications standard Ethernet has been optimized through the addition of quality-of-service mechanisms. Various new IEEE standards will enable Ethernet to reliably transmit several protocols (including real-time-capable ones) in parallel within predefined maximum time limits. Industrial users and car manufacturer are already getting ready to employ it.
The steel arms move perfectly in step with one another and wave their grippers at the viewer. Not even the minutest delay is noticeable when the two industrial robots perform their graceful machine ballet. This perfect coordination is due to a technology that is currently ushering in a new era of industrial communication: Time-Sensitive Networking (TSN).

The tried and tested Ethernet communications standard just got even better: Siemens is one of the drivers behind the development of Ethernet with Time-Sensitive Networking (TSN). (siemens)

For the past 40 years or so, Ethernet has been the undisputed leader when it comes to the transmission of digital data through cables. Siemens has been there from the very beginning and even launched the first Industrial Ethernet network on the market: SINEC H1. As a result, Ethernet was not only used in offices but also, in particular, in industrial manufacturing. However, the standard had a problem from the very start – it could not guarantee that the data packets transmitted by the sender would arrive at the recipient within a certain amount of time. This is an unacceptable situation for industrial controllers – after all, sensor measurements and control signals musn’t take too long to arrive at their destination if a machine is to operate reliably. They need real-time communication within milliseconds – a task for which Ethernet was not originally conceived.

That’s why users who want real-time communication via Ethernet need to employ technological extensions such as the widespread Profinet standard. In machines, for example, this standard connects sensors, actuators, and drives to the central controller by adding real-time data transfer capabilities to Ethernet, enabling applications up to and including the precise control of servo drives. “However, to do that you generally need special hardware components inside the connected devices,” explains Matthias Gärtner, Head of System Management at the Simatic Controller unit of Siemens. “Moreover, the various real-time Industrial Ethernet solutions cannot be run in parallel on the same Ethernet network.”

TSN will enable all data – including real-time information – to be transmitted through a single network in effect simultaneously.

This problem will soon be a thing of the past, because the Institute of Electrical and Electronics Engineers (IEEE), which is responsible for standardizing various systems, has extended Ethernet by adding the urgently needed mechanisms for real-time communication. These include time-controlled transmission, synchronization, and bandwidth reservation. In this way, the IEEE is improving the quality of service by means of TSN. This will enable Ethernet to supply the same time information to all of the connected devices that support these extended standards. As a result, the entire network will be precisely synchronized. In addition, reservation protocols ensure that the data packets are transmitted from the sender to the destination via all the intervening switches according to a predefined timetable. The TSN standards also take into account the topology of the network in question – i.e. whether the network is arranged in the form of a star, a ring, or a line and the number of switches between the sender and the recipient. Moreover, the standards also include seamless redundancy processes.

Attractive for the entire industry: In addition to real time-capable communication within machines, communication between machines can now also happen in real time, improving throughput in the entire plant system. (siemens)

A Single Network for All Data
“It’s a historic moment for Ethernet,” says Gärtner. “In the future, it will be possible to use standard hardware components for Profinet and other real-time industrial communication protocols that are based on TSN. This will enable all data – including real-time information – to be transmitted through a single network in effect simultaneously.” Users will automatically benefit from the steadily increasing bandwidth of standard Ethernet, which will be needed more and more as a result of the increasing IP connectivity of the automation systems. It will also make communication more robust because the switching resources in the TSN switches are firmly reserved for the requested real-time communication needs so that information can no longer be lost due to buffer overflows, for example.

In addition to a rising demand for real-time-capable communication in machines via Profinet, there is also a growing demand for deterministic (i.e. predetermined) data exchange between different machines. Examples include cooperative robots that simultaneously work on the same work piece and so need to precisely coordinate their movements with one another. The OPC UA standard with the PubSub (Publish/Subscribe) extension has now established itself in this area. It can also employ Ethernet with TSN as its transmission medium. “I expect Ethernet with TSN to be introduced into the entire industrial manufacturing process,” says Gärtner. “But that’s not all. Car manufacturer also want to use the new standard to transmit the large amounts of data from reversing cameras within vehicles, for example, or to make autonomous driving possible, which won’t be achievable without onboard networks that incorporate quality-of-service mechanisms.” The time for this has now come. The first TSN components are now being launched on the market and Siemens will use actual TSN products to demonstrate deterministic machine-to-machine communication over OPC UA PubSub at Hannover Messe 2018. These products will be purchasable at the end of the year, when Ethernet with TSN will have finally arrived in the modern world of digitalization and “Industrie 4.0”.

Organised by Fira de Barcelona in collaboration with the Industrial Internet Consortium (IIC), IoTSWC has registered a new growth in the number of participating companies, from 240 in 2017 to 341 in 2018, and expects 14,000 attendees from 114 countries. An evolution in line with the widespread deployment of IoT in various industries due to the potential for improvement in efficiency, automation and results.

Therefore, the director the IoTSWC, Roger Bou, is convinced that the 2018 edition will prove that this technology is here to stay, with its rapidly growing presence in industry: “We can see that no longer is IoT a technological revolution waiting just over the horizon; it is a reality that is being implemented ever more often and has an enormous potential to transform all types of businesses and our day-to-day lives”.

In fact, the Gartner consulting firm has predicted there will be 11.2 billion connected things in the world by the end of 2018 –4.159 billion in industry and specific industries alone. In other words, an upsurge of 32% in these areas with respect to 2017. On the other hand, experts also predict 2018 to be the year in which IoT makes a real impact in the market, spurring new business and service models.

New applications and testbeds

The exhibition area will bring together the leading companies in areas such as information technology, software platform developers, hardware manufacturers, security companies, telecommunications and service operators, or industrial automation firms that will show attendees their latest solutions and applications. The following, among others will be among the 341 companies attending: ABB, Cryptoquantique, Dassault Systems, Deloitte, Fiware, Google Cloud, Hitachi, Huawei, Intel, Kaspersky, Libelium, Microsoft, PTC, Relayr, Rigado, SAS, Software AG, Telefonica, Telit, Thinstream, Uptake, Verizon, Vodafone and Wipro.

Among the new applications, the connected winery developed by Vodafone and Bodegas Emilio Moro stands out which, through a Narrowband IoT platform,sensors in the field, Big Data and satellite technology allow to maximise the performance of the winery and minimise the environmental impact of wine production. In addition, the event will have an area dedicated to testbeds, where live demonstrations of innovative industrial internet applications will be carried out. In total 10 examples will be given, among them an intelligent platform to control water quality in Alaska and save beluga whales; an intelligent entrance gate that can be opened when the owner arrives or transform his/her garage into a giant mailbox for the delivery of online purchases; a 3D printing solution to analyse the client’s foot in real time and design and produce custom-made shoes within a couple of hours; and a fully connected and sensorized fire truck.

The 2018 IoTSWC will also be paying tribute to the year’s most ground-breaking and influential projects with their IoT Solutions Awards, which are open to companies and entities all over the world.

Blockchain, Artificial Intelligence and more

On its side, the Conference will bring together the best global experts in IoT technology and representatives of various industrial industries to address the impact of IoT solutions in different environments. Nine core themes have been established for the 2018 edition, as touchstones for the more than 204 scheduled seminars: connected transport, product manufacturing, healthcare, energy and utilities, construction and infrastructure, open industry, enabling technologies, blockchain and artificial intelligence, with these last two having their very own forums.

The following stand out among the 316 speakers: Jonathan Ballon, VP of Intel; Hajime Sugiyama, Overseas Strategic Planning at Mitsubishi Electric; Seb Chakraborty, CTO of British Gas; Alexander Botsor, innovation Project Manager of BMW; Tomi Teikko, Director of Empathic Building of Tieto; Fabian Simmer, Technology Officer at Seat; Cristopher Bailey, director of Innovation and Architecture at Matson; Francisco Torres, Production manager at Pernod Ricard; and John Denning, CTO of Universal Medical, among others.

The technological gender gap and how to overcome it will also be analysed at the congress. IoTSWC will address the leadership role of women in the IoT ecosystem in a session that will have six women leaders in industrial IoT: Jennifer Bennett, Technical Director, Office of the CTO of Google Cloud; Leila Dillon, VP of Global Marketing & NA Distribution at Big Belly; Helena Lisachuk, Director and IoT Global Leader at Deloitte; Beverly Rider, executive vice-president and commercial director of Hitachi; Eva Schönleitner, vice-president of digital societies at ABB; and Adriana Estévez, Executive Director of Transformation and Digital Innovation at Microsoft.

The content and scope of the event was defined in large part thanks to the involvement of the Industrial Internet Consortium (IIC), a worldwide organization of over 250 companies and entities related to IoT whose aim is to collectively make strides in the industrial Internet. The executive director of IIC, Richard Soley, emphasizes the standard of the attendees and demonstrations of the live systems at the IoTSWC: “IoT Solutions World Congress remains the main industrial IoT event of the year. It gives attendees the chance to meet the leaders who have been working in the field of the IoT for some time; to listen to the experts, for specific companies and industries to share success stories, and also to provide the opportunity to see the benefits of the industrial internet in action with our focus on fully functional test benches”.

Barcelona Industry Week

The IoT Solutions World Congress forms part of Barcelona Industry Week, a brand which also encompasses two other trade shows, In(3D)ustry From Needs to Solutions, dedicated to additive manufacturing, and Healthio, specializing in health and healthcare technologies. All three events, which create synergies and provide a platform for commerce and knowledge in a wide range of industrial sectors, will take place from 16-18 October at Fira de Barcelona.

Many leadless packages cannot be inspected using AOI techniques, so Nexperia pioneered the development of the DFN2020 package with side-wettable flanks (SWF), enabling Automatic optical inspection (AOI) – a critical automotive industry requirement – to be employed. Packages with SWF are now a proven, accepted solution.

Comments Malte Struck, Nexperia’s product manager for small signal MOSFETs: “The DFN package with side-wettable flanks is gaining significant traction with automotive manufacturers as it saves space and can be automatically inspected. Our new 175 °C parts are being used in under-the-hood applications, especially near the engine or gearbox. The unique offering of an automotive-grade MOSFET that is both qualified to 175 °C and which incorporates side-wettable flanks makes the DFN2020 additionally suitable for a wide range of medium-power automotive applications.”

The new automotive-qualified parts extend Nexperia’s low and medium power MOSFET portfolio. Six 40 V and 60 V devices are available with the higher temperature rating and automotive approval, each with low RDS(on) of between 20 mΩ and 40 mΩ.

More information on the new DFN2020 MOSFETs (BUKxxx) including product specs and datasheets is available at https://efficiencywins.nexperia.com/efficient-products/DFN2020-Automotive-MOSFETs.html
