Digitalisation in electrical automation
FFesto is deploying its products and services to meet the challenge of smart production for the future in the course of digitalization.
Festo, the world’s leading supplier of automation technology and technical education, is deploying its products and services to meet the challenge of smart production for the future in the course of digitalization. The company also relies on artificial intelligence and machine learning.
Festo is leading its customers and employees into the digital future. To this end, the company is developing new future-oriented concepts founded on the triad of innovative and energy-efficient technologies, intuitive human-machine collaboration, and education and further training. Festo will be demonstrating this triad at this year’s SPS IPC Drives in Hall 9, Stand 361.
Digitalization and Industry 4.0 – smart products for the future
It is only through self-organising components that production plants become really flexible and thus meet the constantly changing requirements. Consistent standards, norms and interfaces, such as the common OPC UA interface, create the conditions for smart products in the sense of “plug-and-produce” and industry 4.0. Festo has also integrated this universal communication interface into numerous components of electrical drive technology, such as the modular control platform CPX-E, the flexible transport system MCS® (multi-carrier system) and robot controllers.
In addition to integration into higher-level systems, data collection and evaluation play an important role. Here, Festo relies on artificial intelligence, among other things. Festo further expanded this expertise with the acquisition of Resolto Informatik GmbH in April. Resolto has developed a software solution that analyses and interprets data in real time and recognises and reports anomalies. In addition, the system continuously learns through permanent data analysis and expands its knowledge base. This machine learning enables intelligent process monitoring. At the trade fair, visitors can experience the software solution live at the Festo stand. In combination with the new modular controller CPX-E-CEC and the new servo drive CMMT-AS, real-time monitoring is possible. The application shows the detection of faulty batteries. A handling portal lifts the batteries. The Resolto monitoring software monitors the motor currents and position values of the axis. If anomalies occur, e.g. if the handling system grips an incorrect battery format, a message is generated.
Data collection and monitoring can be carried out either by the intelligent software solution close to the components, as with battery handling, or via the IoT gateway CPX-IoT in the Festo cloud. It connects components and modules from the field level, such as handling systems or electric drives, to the Festo Cloud via its OPC UA interface.
Festo is demonstrating the end-to-end connectivity of workpieces and mechanics up to the cloud with a modular production system for customisable USB sticks. This shows the combination of all Festo engineering tools – around the new Festo Automation Suite as well as components and solutions in hardware and software. Visitors can take their personal USB stick, with their name and picture, home as a souvenir of the fair.
Human-Machine Collaboration of the Future
Learning systems with artificial intelligence and robots that work hand in hand with humans play a central role in the production of Lot size 1, the trend towards individualization of products. With the BionicWorkplace, Festo offers a unique concept for human-machine collaboration in the production of the future. In this concept, the bionic robot arm BionicCobot works together with numerous assistance systems and peripheral devices that are networked and communicate with each other. At the same time, artificial intelligence and machine learning methods make the BionicWorkplace a learning and anticipatory system that continuously optimises itself. How sensitive and flexible the human-robot collaboration with the BionicCobot works can be seen by the trade fair visitors in
Hall 9, Stand 361.
Qualification for industry 4.0
Festo Didactic will also be present at the stand with its latest educational offer in the field of automation technology. Increasingly intelligent systems and flexible production processes demand a new qualification of employees for operating digital and intelligent systems. For example, Festo Didactic has developed the cyber-physical learning platform “CP Factory” for practical knowledge transfer. The platform depicts the stations and processes of a real production plant in the form of a learning factory. In addition to this, Festo Didactic also offers many training courses for employees.
Established in 1925, the independent family-owned company based in Esslingen a.N., Germany, has been a driving force in automation for over 60 years and with its unique range of offers has become the world market leader in technical education. In addition to pneumatic drive technology, Festo has also been very successful in electrical automation for over 20 years.
ZEISS unveils a new platform for fast and gentle 3D super-resolution microscopy
ZEISS is introducing ZEISS Elyra 7 with Lattice SIM, a new flexible platform for fast and gentle 3D super-resolution. Lattice SIM expands the possibilities of structured illumination microscopy (SIM): illuminating the sample with a lattice pattern rather than grid lines gives higher contrast and allows a more robust image reconstruction.
Scientists can use 2x higher sampling efficiency to lower the illumination dosage to observe fast cellular processes in super-resolution. High image quality is maintained even at high frame rates.
Fast and gentle super-resolution imaging with Lattice SIM
Lattice SIM enables fast imaging of 3D volumes with up to 120 nm laterally. Thanks to greater light efficiency, the new Lattice SIM technology provides scientists with gentle super-resolution imaging of living specimens with 255 frames per second.
Using less light to illuminate the specimen means scientists can image longer with less bleaching of the sample. The novel Lattice SIM technology allows new mechanistic details to be uncovered and the finest sub-cellular structures in large fields of view to be quantified.
Optimized localization microscopy with SMLM
ZEISS Elyra 7 can be expanded with single molecule localization microscopy (SMLM) for techniques such as PALM, dSTORM, and PAINT. ZEISS Elyra 7’s SMLM module delivers molecular resolution in large 3D volumes and powerful post-processing algorithms for quantification.
Researchers choose freely among labels when imaging with resolutions down to 20 nm laterally. SMLM provides access to molecular mechanisms in both fixed and living specimens. Researchers can count molecules and come to understand, molecule-by-molecule, how individual proteins are arranged within a structural context.
Fast optical sectioning with the new Apotome mode
ZEISS Elyra 7 is highly flexible: users profit from the wealth of options of a research grade, live cell microscope from ZEISS. They can expand their ZEISS Elyra 7 with various contrasting techniques and combine them with optical sectioning. The new Apotome mode allows fast optical sectioning of 3D samples. ZEISS Elyra 7 also works seamlessly with ZEISS SEMs in a correlative workflow.
New perspectives for life sciences research
Life sciences research often requires you to measure, quantify, and understand the finest details and sub-cellular structures of the sample. Scientists may be working with tissue, bacteria, organoids, neurons, living or fixed cells and many different labels.
ZEISS Elyra 7 takes them beyond the diffraction limit of conventional microscopy to image samples with super-resolution. Researchers now examine the fastest processes in living samples – in large fields of view, in 3D, over long time periods, and with multiple colors.
LoRa-enabled IoT solutions connect industrial equipment to cloud
Semtech (www.semtech.com) announced that EasyReach Solutions, an Indian startup specializing in smart IoT solutions for industrial applications, has incorporated Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) into its industrial and smart vehicle monitoring products.

TSN; A Milestone for Industry
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).
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.
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”.

Interview about TSN: “Ideally Prepared for the Future”
Siemens is one of the driving forces behind the development of Ethernet with TSN. Sven Gottwald, Head of System and Vertical Management for Industrial Communication and Identification, explains how the application of the new standard benefits users.
Why is Ethernet with TSN such an important development?
Because it means that we no longer need different Industrial Ethernet solutions for deterministic communication in industry. In the future, they will all run on the widely used Ethernet with TSN and can do so in parallel without restrictions. This includes Profinet, OPC UA PubSub, and all other TCP/IP-based protocols. This convergence is a huge benefit for industrial users, because it enables all types of data to be transmitted through a single physical network in which time-sensitive information always has precedence so that it reliably arrives on time. That’s precisely what companies need in order to fully exploit the potential of digitalization and “Industrie 4.0”.
How does Ethernet with TSN regulate the “timetable” for the data?
The Institute of Electrical and Electronics Engineers (IEEE), which is responsible for the standardization, provides two options for this: It’s either done by a central unit or the connected devices negotiate it among themselves. As a member of the “Labs Network Industrie 4.0” (LNI4.0) testbed, Siemens prefers the second option because the use of a central unit requires extensive reconfiguration every time a change occurs in the network. However, if the system configures itself, it’s easy to integrate new devices. That’s why we talk of “Plug & Work”-capable networks, which greatly benefit our customers.
What is Siemens doing with regard to Ethernet with TSN?
The entire automation industry is working hard on this topic of course. However, Siemens is certainly one of the leading companies in this area. We are actively involved in all of the major standardization bodies, such as the IEEE, the IEC, the OPC-F, and the PI. We also supply the editor for some of the TSN IEEE standards.
The first TSN products will start shipping before the year is out. That’s why our customers are ideally prepared for the digital future with Siemens.
