Siemens and Google Cloud to cooperate on AI-based solutions in manufacturing

The release came to me jointly from Siemens and Google reminding me that this year’s Hannover Messe is the first German trade show in my career where Siemens did not monopolize a great amount of my time. No press conference invitation, no appointments, booth tours, or news of any kind came my way. Of course, the American PR team that I’ve worked with forever has been disbanded. Weird.

Google Cloud has joined the race with Microsoft Azure and Amazon’s AWS in the manufacturing space as IoT has driven cloud adoption. With so much data moving to the cloud, AI and ML technologies beg to be used to ferret out insights. Hence this collaboration.

Google Cloud and Siemens, an innovation and technology leader in industrial automation and software, announced a cooperation to optimize factory processes and improve productivity on the shop floor. Siemens intends to integrate Google Cloud’s leading data cloud and artificial intelligence/machine learning (AI/ML) technologies with its factory automation solutions to help manufacturers innovate for the future. 

Data drives today’s industrial processes, but many manufacturers continue to use legacy software and multiple systems to analyze plant information, which is resource-intensive and requires frequent manual updates to ensure accuracy. In addition, while AI projects have been deployed by many companies in “islands” across the plant floor, manufacturers have struggled to implement AI at scale across their global operations.

For more than 170 years, Siemens has built its business on pioneering technologies that have led the manufacturing industry forward. By combining Google Cloud’s data cloud and AI/ML capabilities with Siemens’ Digital Industries Factory Automation portfolio, manufacturers will be able to harmonize their factory data, run cloud-based AI/ML models on top of that data, and deploy algorithms at the network edge. This enables applications such as visual inspection of products or predicting the wear-and-tear of machines on the assembly line.

Deploying AI to the shop floor and integrating it into automation and the network is a complex task, requiring highly specialized expertise and innovative products such as Siemens Industrial Edge. The goal of the cooperation between Google Cloud and Siemens is to make the deployment of AI in connection with the Industrial Edge – and its management at scale – easier, empowering employees as they work on the plant floor, automating mundane tasks, and improving overall quality.

“The potential for artificial intelligence to radically transform the plant floor is far from being exhausted. Many manufacturers are still stuck in AI ‘pilot projects’ today – we want to change that,” said Axel Lorenz, VP of Control at Factory Automation of Siemens Digital Industries. “Combining AI/ML technology from Google Cloud with Siemens’ solutions for Industrial Edge and industrial operation will be a game changer for the manufacturing industry.”

“Siemens is a leader in advancing industrial automation and software, and Google Cloud is a leader in data analytics and AI/ML. This cooperation will combine the best of both worlds and bring AI/ML to the manufacturing industry at scale. By simplifying the deployment of AI in industrial use cases, we’re helping employees augment their critical work on the shop floor,” said Dominik Wee, Managing Director Manufacturing and Industrial at Google Cloud.

Software-centric Automation Hannover Messe Update from Schneider Electric

Schneider Electric has been publicizing an implementation of the decoupled control hardware and software envisioned by the Open Process Automation Forum using IEC 61499. https://themanufacturingconnection.com/2021/02/schneider-electric-updates-ecostruxure-automation-expert-forges-strategic-agreement-with-wood/ For example, a recent post from the blog.

At last week’s Hannover Messe, Schneider Electric used its press conference to tout some updates to its Ecostruxure Automation Expert.

The press release is included below for your information, plus a bonus press release regarding a new, smaller footprint UPS.

First, a couple of notes. I listened recently to some software developers discussing the benefits and drawbacks of version numbering their software. The traditional way is to begin with version 1.0  and then increment. Of course, no one (or few?) buy version 1.0 which is typically pretty buggy. An alternative is to version number by year thus avoiding the dreaded V 1.0. Automation Expert has just been released a couple of months ago as Version 21.0. The new release discussed below is version 21.1.

Someone, I know not whom, asked a pointed question during the press conference. Schneider points to its offering following the IEC standard. The questioner wanted to know if Automation Expert was just another proprietary software with some standards baked in. The question was not answered directly. The answer given dealt with decoupling hardware and software allowing each to be independently upgraded. Good question to keep in mind if other companies dive into this water. Or—perhaps there is room for an independent software developer to jump into the fray if and when.

Automation Expert V21.1 Release

Schneider Electric released version 21.1 of EcoStruxure Automation Expert, its software-centric universal automation system. Adoption of the new technology is proving immediately beneficial for consumer-packaged goods, pharmaceutical and logistics enterprises. 

“EcoStruxure Automation Expert v21.1 is an important milestone in our journey to help manufacturers achieve the step-change advancements possible with a digital-first approach to industrial automation,” said Fabrice Jadot, Senior Vice President, Next Generation Automation, Schneider Electric. “Today’s operations need to react quickly to fluctuating market and environmental dynamics and rapidly mitigate potential risks. By separating the hardware and software lifecycles, EcoStruxure Automation Expert enables automation applications to be built using asset-centric, portable, proven-in-use software components, independent of the underlying hardware infrastructure. This software-centric approach delivers unprecedented cost and performance gains and frees engineers to innovate by automating low-value work and eliminating task duplication across tools.”

GEA is one of the largest technology suppliers for food processing and a wide range of other industries. The company focuses on technologies, components, and sustainable solutions for sophisticated production processes in diverse end-user markets where time to market and agility is essential. EcoStruxure Automation Expert greatly simplifies the integration between operational technology (OT) and information technology (IT) creating new agility for GEA and its customers.

Master Systèmes, an industrial automation system integrator and Schneider Electric Master Alliance partner, is using EcoStruxure Automation Expert to increase the agility and flexibility of one of its cosmetic customer plants.

Schneider Electric is also implementing EcoStruxure Automation Expert in its own Smart Distribution Center in Shanghai, China to reduce costs and improve efficiency.

Because the software is decoupled from the hardware, modifying the conveying line to adapt as flow requirements change is easier and more cost-effective. With EcoStruxure Automation Expert, identifying the root cause of failure and troubleshooting is four times faster. And with 45% less products on the error line, throughput is increased by 5.3%.

Among other advancements, EcoStruxure Automation Expert V21.1 includes: enhanced cybersecurity, diagnostics, discovery and commissioning features, and expanded libraries and language support.

In addition, improved integration with AVEVA System Platform ensures EcoStruxure Automation Expert customers can take advantage of AVEVA’s market leading software for supervisory, enterprise SCADA, MES, and IIoT applications with minimal engineering overhead. One study showed the EcoStruxure Automation Expert and AVEVA combination reduced engineering efforts by over 50%.

Ultra-Wideband Locator News From Hannover

Most of my interviews and press conferences seemed to focus on software. In this event, I chatted with Cris Masselle, chief marketing officer of WISER systems

I was aware of RFID systems from the 90s for location applications. In fact, I quoted a system to a customer for tracking unique builds of product down the assembly line back then. But we went with a barcode system due to the customer’s experience with lack of reliability with RFID.

Masselle told me that we’re on a second generation of UWB technology. WISER, a woman-owned and founded technology company headquartered in Raleigh, North Carolina, has developed an innovative UWB Locator delivering scalable real-time location in nearly any environment. 

The system autonomously reports precise (sub-meter or inch-level) coordinates via a computer or mobile device and is accurate even in cluttered, metallic, or complex manufacturing environments where conventional tracking technologies perform poorly. The system is lightweight and portable and can be deployed in minutes, indoors or out. Although WISER’s Locator has only been on the market for a few years, 25% of end customers are Fortune 500 companies, including several large aerospace and defense contractors, multiple U.S. Government agencies, and a large Japanese automotive company, among many other organizations. WISER manufactures its products in North America.

From the press release:

The WISER Locator is an ultra-wideband (UWB) wireless business process management solution that autonomously generates precise positioning data in real time. WISER’s best-in-class Locator utilizes proprietary Redundant Radio Localization and Tracking (RRLT) technology, which ensures precise and reliable performance even in reflective or cluttered environments where radio frequency technologies often fail. WISER’s real-time location updates enable end users to automate reporting on location-based processes, to conduct time-motion studies, and to track and trace critical assets in real time, among many other uses.

“This will be our first time exhibiting at Hannover Messe, so I’m eager to see how conference attendees react to what we have to show them,” said WISER CEO Dr. Elaine Rideout. “So many of Hannover Messe’s tracks and topics are right in line with WISER’s mission. To date, our technology has garnered especially strong interest from leaders in smart manufacturing, process automation, and logistics endeavors like yard management—all directly relevant to Hannover’s focus on Industry 4.0. It’s always exciting to showcase our Locator system to new audiences.”

Early adopters of the WISER Locator have utilized this wireless system for applications including: work-in-progress tracking in automotive, aerospace, and heavy equipment factories; real-time location for vehicles in large yards and lots; location-based process heat-mapping for factories and other settings; and track and trace applications for smart warehousing and inventory management.

Controlled Flying Birds and Workforce Development Highlight Festo Hannover Announcements

I remember the first trip I made to Festo in Germany many years ago. I thought, this is “just” a pneumatics company. What could be interesting about this trip? Then I witnessed what their R&D engineers did with pneumatics. And saw that the company if far deeper than “just” pneumatics.

Even though we could not experience in the flesh, so to speak, this year’s press conference and demonstrations did not disappoint. The company discusses financial results, strategy, general information, an application – assembly of insulin injection pen, workforce issues, and the always delightful demonstration of pneumatic/electronic far-out thinking with this year being a bionic swift (bird).

Most companies I work with have an education and training component. Festo has a division that is dedicated to education from children to adults. Check out the Festo Didactic information below. Maybe you can purchase a bionic bird education kit for your local school’s science and technology program (see information below). I’m living in a new community, but I’m looking for local contacts to help out.

Financial years 2020/2021

Festo’s results were stable despite the pandemic. The Festo Group had to cope with a 7.5% decline in turnover in the 2020 financial year due to the pandemic. Turnover was 2.84 billion euros (previous year 3.07 billion euros). Overall, however, thanks to forward-looking cost-cutting measures and employment protection, the operating result in 2020 was slightly higher than in the previous year.

“This has enabled us to guide our workforce safely through the crisis year and to create a good basis for being ready for the global economy to pick up again. At the same time, it gives us the financial freedom to invest in our future now as well,” said the Chairman of the Management Board, Dipl.-Ing. Dr. h.c. Oliver Jung.

As in the previous year, the company’s R&D ratio was 8% of turnover. 

For 2021, the company expects a catch-up year. “We started the year well, with strong growth in the first quarter. Nevertheless, the end of the pandemic cannot yet be estimated. We are therefore continuing our savings course. At the same time, we continue to invest in our growth and innovation strategy,” Jung affirmed.

Strategy 2025+

Digitalisation and AI determine the product roadmap with smart and intelligent products as enablers for energy efficiency and sustainability in customer solutions.

Festo is focusing on the capability shift upgrading employees’ skills in the digital transformation.

The need for home schooling and virtual training (Digital Education) is growing rapidly in the pandemic. In the lockdown, Festo Didactic successfully launched its new digital learning platform, Festo LX, for technical education and provided a free homeschooling version for mechatronics courses in schools.  

The LifeTech business segment with medical technology and laboratory automation is experiencing a real boom with growth rates of over 100%. Festo is continuously expanding its Technical Engineering Center for LifeTech in Boston, which opened in 2018 and is one of the world’s most important development locations for life science, in order to further develop this promising growth market.

Festo’s products make an important contribution to the fight against COVID 19. In particular, laboratory automation enables high throughput in COVID 19 tests.  Automation is also key in vaccine development and production.

Sustainability needs automation and education

“As a company and society, we have to manage the balancing act in the pandemic of simultaneously finding ways out of the crisis and focusing our future activities on sustainability. Automation and technical education are a key to this. We also have a high social responsibility for sustainable development here,” said Jung. The goal is to gradually develop production in the direction of a circular economy.

“At Festo, we are convinced that pneumatics in particular offers massive advantages over electrics in many areas, and that no other technology can match it. We are currently developing this further in the direction of smart and digital pneumatics. There is still a lot of potential here,” confirmed Jung.

In 2020, Festo has also made great progress internally in climate protection and thus towards its climate target of saving at least 30% CO2 by 2025 (Scope 1 and 2).

Festo has the greatest leverage for climate protection with its customers, through the appropriate product selection of pneumatics and electrics (Scope 3). This is because around 90% of CO2 emissions are generated during product operation and only around 10% during production. Smart products and services, digitalization and AI are giving new impetus to energy efficiency on the way to CO2-neutral production.

As a family-owned company, Festo thinks and acts responsibly and with a long-term perspective. Festo stands for clear values, utmost quality and customer-oriented innovation. It has set standards in industrial automation technology and technical education ever since its establishment, thereby making a contribution to sustainable development of the environment, the economy and society.

Festo is advancing digitalisation in all its corporate divisions. 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.

Productivity – Festo’s core competency

Innovation for the best possible productivity, a global presence and close, long-term partnerships with its customers are the hallmarks of Festo. In the 1950s, Festo became the first company in Europe to use compressed air as a drive medium in automation. The company now offers over 30,000 products and system solutions for pneumatic and electrical automation technology which, thanks to a large variety of modular systems, can be tailored to specific customer applications in many different factory and process automation industry segments.

Added value through digitalisation
           
Smart products, connectivity, the mining and interpretation of data, including via the cloud, and dashboards for visualisation, already offer added value for customers. Products like the energy efficiency module E2M, IO-Link-capable components, the CPX-IOT gateway or interfaces like OPC-UA contribute to this process. Another basic requirement for successful and consistent digitalisation is mechanical, electrical and intelligent connectivity through software solutions, enabling all customers to find their bearings quickly and intuitively. 

Festo is promoting this with an open automation architecture and a large product portfolio made up of axes, motors and controllers. Standardised software tools are also being developed: configurators for smart engineering, the Festo Automation Suite for easy commissioning and the digital maintenance manager Smartenance for reliable operation. Digitalised pneumatics such as the Festo Motion Terminal VTEM makes pneumatics more flexible than ever before. The reason: apps define the function, the hardware remains the same.

In addition, data analytics, machine learning and artificial intelligence are shaping the agile product development of the future. Since 2018, the competence in the field of AI has been strongly expanded. The Festo AX (Festo Automation Experience) software platform is an AI-based software solution that allows production processes to be improved, e.g. with preventive maintenance of assets and machines, monitoring of quality in production or energy consumption.

With AI-based solutions for operations and maintenance processes, the overall equipment efficiency (OEE) of customers is to be improved.

Qualification in the digital transformation

As a leading provider of technical education and training, Festo Didactic is responding to current megatrends such as digitalisation and the energy transition. Because these trends are changing industry and production processes. Festo Didactic supports its customers with learning solutions and supports them to ensure the employability and productivity of employees and companies.

Festo Didactic offers a comprehensive range of learning solutions. Learners acquire technology knowledge and soft skills both in team-oriented and practical training on physical learning systems with industrial components, but also location- and time-independent through digital online learning opportunities. The new digital learning portal Festo Learning Experience (Festo LX) creates individual learning experiences for learners and teachers.

The fast way to a safe insulin pen

Syntegon’s assembly system for medical technology with the Festo automation platform 

Diabetes is on the rise worldwide with around 10 million people being diagnosed with the disease every year. This pushes up the demand for insulin pens for self-injection. Syntegon’s Danish subsidiary has developed an automated system for assembling these pens using the Festo automation platform.

“I have a dream,” says Michael Andersen, Sales Director of Syntegon Technology Sandved in Denmark. “I have a dream of our machines doing on-the-fly format changes. That would be the culmination of our philosophy of flexibility and agility that we strive for in our company,” adds the automation expert.

Flexibility and agility

“By using the Festo automation platform, which includes the servo press kit, we are already very close to making this dream come true,” says Andersen. In fact, Festo’s servo press kit YJKP – a preconfigured modular system consisting of software, controllers and standard electrical drives – can be easily integrated in the plant and offers a high degree of flexibility thanks to the preinstalled software. This means that the modular press system with servo drive for electric pressing and joining up to 17 kN is ready for immediate use and, compared to similar solutions on the market, is both intuitively to parameterize and cost-effective.

“We have installed more than a 100 servo press kits in the automated assembly lines for insulin pens,” says Ulrik Keldke, Head of Syntegon’s engineering department in Sandved. The precisely adjustable pressing and joining forces ensure consistent quality and low reject rates. “What we particularly like about the Festo servo press kit is that it’s quick and easy to commission, and the machine operators don’t need to be trained to use it,” explains chief engineer Keldke.

Quality and safety

“Automating the assembly line is a prerequisite for meeting the requirements for the end product: the insulin pens must be safe and user-friendly,” says Andersen. The pens must not break when used by the patients, as that would put them at risk. The Servo Press Kit keeps the tension and pressure constant. “The glass of the syringes should never be subjected to irregular pressure as they would break,” Keldke says. The automated systems ensure that the insulin pens are always in order and can deliver the exact amount of insulin.

Depending on the machine type, Syntegon’s assembly lines produce up to 300 pens per minute. The degree of automation is scalable according to requirements and can also be adapted at a later date. The machine concepts are based either on a rotary table for low to medium outputs or on a linear transport system for high outputs. The system can be expanded with automatic feeders and stations to increase output and the degree of automation.

Consistency and reliability

Syntegon Technology, formerly Bosch Packaging Technology, sees itself as a provider of integrated solutions. The assembly line for insulin pens can be expanded into a complete line with other systems from the company. Pharmaceutical manufacturers can thus be provided with machines for all process steps, from filling, capping, assembly, testing, to labelling and packaging – preconfigured and from a single source.

The machine control system is based on electrical and pneumatic components and modules from the Festo automation platform. This ensures a consistency of supply since Festo products are available worldwide and offer open interfaces to higher-level controllers. The CPX-E-CEC module from Festo establishes the connection to the process control level, allowing it to be used with Profinet or, for other customers in Europe, with EtherCat. Especially for North American customers, however, the system could also be supplied with an Ethernet/IP module.

Bionic Swift: A Bionically Inspired Robotic Bird

So, the cool demonstration this year was the Bionic Swift. This year’s engineering innovation has been incorporated into the “Bionics4Education” program. Its target market is high school education and also industrial training. 

It is one of the oldest dreams of mankind: flying like a bird. The lift and propulsion of birds have been ingeniously achieved by nature. Birds measure, control and regulate their movements continuously and completely autonomously. The inspiration for the development of the Bionic Swift educational kit came from the Bionic Learning Network, a research association with universities, institutes and development companies whose goal is to produce novel technology carriers through the application of bionics. In 2020, the BionicSwift was presented to the public for the first time. Festo Didactic wants to bring the world of bionics together with the education sector in order to promote working in interdisciplinary project teams as well as problem-oriented learning and creativity at schools.

The Bionic Swift is a robotic bird inspired by the bird world. Festo based its development on the natural model of the swallow. With the experimental set, scientific and technical correlations as well as the fascination of bird flight and the topics of lightweight construction, energy efficiency and aerodynamics can be impressively conveyed in STEAM lessons using a project-based approach.

The mechanisms of action of the flap of the wings can be explored in a playful way by students in class. Weighing less than 45 grams, the ultra-light flying object Bionic Swift shows particularly agile flight behaviour. Due to its extreme manoeuvrability, even tight turns can be realised. The Bionic Swift experimental set is recommended for up to three learners and from the age of 15. 

The references to biology and technology that can be taught in STEAM lessons or at extracurricular learning venues are numerous and reach from the structure of tubular bones to wing take-off and landing to the basics of movements in the air. This allows teachers to teach technical learning content via a new, cross-curricular educational learning path. Accompanying teaching material, as well as the assembly manual, can be downloaded free of charge from our website

CIP Security, Resource-Constrained EtherNet/IP Devices, Updated Terminology Headline ODVA Hannover News

ODVA’s annual Hannover Messe press conference highlighted new technologies that extend EtherNet/IP and CIP Security to “resource-constrained” devices. Thanks to advance in 2-wire Ethernet, devices that were too small or too inexpensive for a network chip can now join the EtherNet/IP network. There is an international movement to change traditional networking terminology, for example “master-slave”, that would be offensive to many. Here are the news releases.

CIP Security

ODVA announced that CIP Security has added support for resource constrained EtherNet/IP devices. CIP Security can now provide device authentication, a broad trust domain, device identity via Pre-Shared Keys (PSKs), device integrity, and data confidentiality for resource-constrained devices such as contactors and push-buttons. Additionally, a narrow trust domain, user authentication, and policy enforcement via a gateway or a proxy are available options. 

The recent integration of single pair Ethernet has opened up the door to overcoming lower-level device constraints and ultimately to expanding the footprint of EtherNet/IP. Adding simpler devices to EtherNet/IP allows for the benefits of additional remote diagnostics, asset information, and parameterization capability. The addition of more nodes to the network within the context of IT/OT convergence makes device level security a fundamental need to ensure that indispensable assets and people are protected from physical harm and monetary loss. 

The new CIP Security specification has added a Resource-Constrained CIP Security Profile in addition to the EtherNet/IP Confidentiality and the CIP User Authentication Profiles. The Resource-Constrained CIP Security Profile is similar to the EtherNet/IP Confidentiality Profile, but is streamlined for resource-constrained devices. The same basic security aspects of endpoint authentication, data confidentiality, and data authenticity remain. Access policy information is also included to allow a more capable device, such as a gateway, to be used as a proxy for user authentication and authorization of the resource constrained device. 

Implementation of CIP Security for resource-constrained devices requires only DTLS (Datagram Transport Layer Security) support instead of DTLS and TLS (Transport Layer Security), as it is used only with low-overhead UDP communication. 

Terminology Updates

ODVA announced that the April 2021 publication of the DeviceNet and ControlNet Specifications have replaced the usage of the words “master” and “slave” within ODVA references. Developers of devices for ODVA networks will now utilize the words “client and server” (EtherNet/IP, including the integration of Modbus devices), “controller and device” (DeviceNet), and “system time supervisor or active keeper” (ControlNet) to describe these functions. With the goal of eliminating terminology that is hurtful, these changes are the first in a series to update the entire library of ODVA specifications and documents to rectify the use of these terms. 

EtherNet/IP for Resource-Constrained Devices

ODVA announced that The EtherNet/IP Specification has been enhanced to allow vendors to bring the network to resource-constrained devices in-cabinet, including push buttons and contactors. Cost, size, and power restrictions have historically limited the usage of EtherNet/IP at the edge, where many nodes are still hardwired. However, the continued decrease in the cost of semiconductor chips has enabled increased connectivity of simple devices, as evidenced by the rapid expansion of the Industrial Internet of Things (IIoT). The sustained, strong growth of EtherNet/IP combined with accelerating IT/OT convergence has made it possible to deploy EtherNet/IP within cabinets on lower-level automation devices such as contactors and push buttons.

The inclusion of resource-constrained devices within cabinets on an EtherNet/IP network is enabled by recently published enhancements to The EtherNet/IP Specification including the physical layer In-Cabinet Profile for EtherNet/IP along with low overhead UDP-only resource-constrained EtherNet/IP communication. Resource requirements have been reduced via enhancements such as an IT friendly LLDP node topology discovery mechanism, auto-commissioning support, and auto-device replacement support. Additionally, a specification for a new select line circuit facilitates the efficient delivery of system wide sequential commands. 

The EtherNet/IP in-cabinet bus solution reduces interface components through use of single pair Ethernet (IEEE Std 802.3cg-2019 10BASE-T1S) and reduces node cost via multidrop cabling that spans a single cabinet with one interface per device and one switch port that supports many devices. Cost is further reduced via cables that use composite network and control power to eliminate separate parallel runs. The select line for topology eliminates configuration switches by enabling discovery based on relative position and allows for direct connection with programming tools during assembly for parameterization. Assembly time is lowered by eliminating most wire or cable preparation with insulation displacement (piercing) connectors. Nodes will also be able to be replaced with compatible nodes of the same type during normal system operation without any engineering tools in a plug and play manner. 

This will be made possible through reduced hardware requirements enabled by UDP-only EtherNet/IP communication, usage of single pair Ethernet, and shared in-cabinet external power and cabling. Adding low-level in-panel devices to the network will enable the benefits of additional remote diagnostics, asset information and parameterization capability, automatic node topology discovery, and plug and play device replacement.
