A few weeks ago the World Climate Conference was held to discuss sustainability targets for lower energy consumption and less pollution. Few organisations have embraced the goals but Festo, at its Scharnhausen Technology Plant in Germany, has already shown its support for them in the Industrie 4.0, energy efficient, IoT-enabled factory
Energy efficiency often starts from the ground up in manufacturing environments and, for Festo, a major decision was to develop an energy efficiency module that is a plug-and-work solution for the pneumatic circuit as a whole. The module is able to summarise, evaluate and analyse data by using artificial intelligence (AI). The data collected can therefore be pre-processed inside the unit and/or completely transferred into a cloud. A decentralised automation platform usually collects data from different Festo devices and combines them on a valve terminal with Codesys controller on board.
In the Festo Technology Plant at Scharnhausen, this type of installation has been retrofitted to all older machines since 2015 – and is a must for all new machines. The target was to make them energy transparent and to optimise air and current consumption by dedicated switching-on and off cycles depending on several criteria – thus avoiding that energy peaks are just added without any benefit, or leakage causing high extra cost. Data had been fed via object linking and embedding (OLE) for process control (OPC) unified architecture (UA) into the on-site manufacturing execution (ME) system from SAP by its plant connection module (PCo), and further to the enterprise resource planning (ERP) system with SAP HANA cloud. Now the new solutions allow – in conjunction with other actions taken like solar panels or re-use concepts for heat – saving of up to one-third of energy compared to the old plant. Amortisation is expected to be around two years.
In the latest use cases, the data from such energy efficiency modules is brought via OPC-UA and a Festo CPX-IoT Gateway to cloud or IoT platforms like Siemens MindSphere or Rockwell Factory Talk. Festo also provides its own cloud for deeper analytics of all its pneumatic and electric drive components and mechatronic sub-systems as a long-term target. Data is also fed into SAP HANA, Festo’s on-site option in the Scharnhausen factory.
The required apps are developed by Festo, and in the case of external cloud providers, are then installed in the MindSphere environment (using Siemens MindConnect LIB) or the Rockwell Device Analytics (via Shelby Appliance or Team ONE tools). The app for the Festo energy efficiency module inside these clouds or IoT environments allows easy visualisation, quicker set-up and parametrisation of the product and online visualisation during machine run-time. The data analytics support advanced diagnostic and condition monitoring concepts and could lead into predictive maintenance systems by combining data from different sources inside the cloud.
Today, a cloud based visualisation makes many things easier, but a high degree of expertise and IT knowledge is needed to make the devices communicate to clouds offered by the market today. In total, the Festo energy efficiency module reduces energy cost, and […]

Eberhard Klotz is the head of the Industrie 4.0 campaign at Festo, a supplier of automation technology and industrial training and education programmes. In this article he discusses the company’s activities in IoT, its view of production of the future, benefits for original equipment makers (OEMs) and end-users and partners in industrial markets with Matt Wilkins, a senior analyst of IoT Research at Strategy Analytics
Matt Wilkins: Industrie 4.0 is a key aspect of the implementation of the Internet of Things in the industrial market, what does Industrie 4.0 mean to Festo?
Eberhard Klotz: At Festo we view Industrie 4.0 as the process through which we get to the production of the future. Festo has a holistic view of the changes in the production world, considers different perspectives and, in addition to technology, also takes other key points into account, such as the interaction between man and machine, and the issue of training.
Eberhard Klotz, Head of the Industrie 4.0 campaign at Festo
The real and virtual world are growing increasingly closer: modern information and communication technologies are merging with industrial processes, increasingly changing the production landscape and the interaction with individual customers.
Industry 4.0 brings together various activities under one umbrella and describes the change that is imposing new requirements on production systems, machines and people in many areas. Festo is part of the Industrie 4.0 steering team that includes government ministries, several official bodies, along with Siemens, Bosch, SAP and Deutsche Telekom.
MW: What does production of the future look like?
EK: The first thing is that production systems will be fully connected. There will be intelligent, selfregulating and self-controlling components for plug-and-produce. Production plants will be highly flexible, allow for economical manufacturing of small batch sizes, fast balancing of the workload in a production network – including logistics, and fast adjustment to the orders in hand.
Matt Wilkins, Strategy Analytics
Finally, there will be comprehensive condition monitoring which helps to avoid or reduce downtime and optimises maintenance procedures and mobile maintenance. Essentially the faster we can be aware of an issue and analyse it, the faster we can implement a repair before a minor issue becomes a major one. Digital twins and a virtual set-up of a smart factory also allow pattern matching and detecting random errors, thus optimising downtime as well as process optimisation online.
MW: If Industrie 4.0 is the process which takes us to the production of the future, that must surely require a constant focus on refining and developing?
EK: Festo has been at the forefront of factory automation for many years. The research department helps shape the production systems of the future. So it is looking at mechatronics, the latest simulation technologies, microsystem technology and intelligent components for Industrie 4.0. In our view innovation management creates the necessary framework to turn good ideas, knowledge and technology into successful commercial products.
Our research activities include the ENTOC (Engineering Tool Chain for Efficient and Iterative Development of Smart Factories) research project, where the aim is to significantly reduce the time taken and complexity […]

Mobile tariffs are in a continual state of change, as providers reshape and repackage mobile offers. Coupled with the sheer breadth and depth of information that these offers create, service providers, regulators and consumers struggle to compare, rank or benchmark different propositions and average price points.
The Teligen division of Strategy Analytics has been tracking this pricing minefield globally for over twenty years, within its OECD Mobile Voice Price Benchmarking Service. The quarterly-updated Excel-based system incorporates the internationally acknowledged OECD methodology, and is based on the top two providers across 36 countries.
In an extension to this already comprehensive coverage, it has now launched a premium version of the service, which includes additional providers in five European markets; France, Germany, Italy, Spain and the UK, as well as in the US, to cover providers with at least 80% combined market share (typically 4-6 providers per country).
Analysis of the extended coverage within these six markets shows that for a user making 100 calls a month (just over 180 minutes), sending 140 text messages, and using 2GB data can save, on average, over USD PPP 200 a year, depending on choice of provider. The graph below shows how costs in these extended markets compare for this basket.
Source: OECD Mobile Voice Premium Service, November 2017 (custom country & provider selection)
“Italian provider Tre is an example of where major cost savings can be found. It is currently offering an incredibly competitive tariff – ALL-IN Start, which gives users 500 minutes, 500 texts and 5GB of data a month for €5, with a six month promotional offer of 4G LTE speed at no extra cost (thereafter €1 per month). Without the 4G option, this works out at just under USD PPP 80 per year.
This is half the cost of the cheapest offer from WIND, which merged with Tre in 2016, and over 75% cheaper than its closest priced competitor, TIM. Of course, it is important to look at the specifics of each offer and consider it in the context of the specific usage profile, but in any event, this represents a significant cost saving” stated Josie Sephton, director of Strategy Analytics’ Price Benchmarking division, Teligen.
According to Angela Toal, senior tariff analyst with Teligen “while the Italian example is especially dramatic, large differences in costs can be found in other countries. The new Premium service gives access to much more in-depth coverage of providers in selected markets, allowing for a much greater insight into what the key competitors are really up to”

Without redundancy, there is no automated driving. The promise of automated driving requires a mix of technological, societal and regulatory development and co-operation. The technology continues to advance thanks to sensors and software, but also thanks to redundancy. In order to realise fully-automated driving on the path to the accident-free future, redundancy in safety-critical systems such as braking and steering is an absolute.
Bosch is actively developing and bringing to market redundant braking solutions to support all levels of automation as defined by SAE. At the 2018 North American International Auto Show, the leading global supplier of technology and services will showcase its braking solutions, including redundant braking for automated driving.
“The importance of redundancy for the rollout of automated driving goes beyond just the technological function as it ultimately will build confidence in consumers as they understand these systems are designed with deep levels of complexity to handle a variety of situations,” said Mike Mansuetti, president of Bosch in North America.
SAE level 3 (conditional automation) vehicles will begin to hit the market as soon as 2018. For these vehicles, a human driver is still necessary, but safety-critical functions may be completely shifted to the vehicle under certain traffic or environmental conditions.
Drivers must still remain present, but will need a certain amount of time to realise that an intervention is necessary. Redundant functions ensure that all safety-critical functions continue during this time span, even in the rare case of a failure in the system. For SAE levels 4 and 5, the redundancy becomes even more critical as the time span increases without the driver in the loop.
Bosch’s solution for a fail-degraded brake system (steering system and EE architecture) is the combination of its electromechanical brake booster iBooster and ESC (Electronic Stability Control), also known as ESP® (electronic stability program), systems. Both are independently capable of performing braking functions for the vehicle in the rare case of a single failure.
The technological breakthrough of redundant braking was achieved by modifying one system element; the vacuum brake booster is replaced by an intelligent electro-mechanical booster, the iBooster. A conventional brake system today comprises two actuators: a vacuum brake booster and ESC unit.
The redundant brake system is comprised of two actuators that are each able to decelerate the vehicle independent of the driver applying the brake pedal. Even if a failure occurs in the brake system, either actuator (iBooster or ESC) is able to avoid wheel lock-up by modulating the brake pressure, which maintains the ability to steer during deceleration.
Bosch’s redundant brake system for automated driving was named a finalist for the 2018 Automotive News PACE (Premier Automotive Suppliers’ Contributions to Excellence) Award, which is acknowledged globally as a prestigious industry benchmark for automotive supplier innovation. Bosch was also honored with an eMove360° Award in the category of Automated Driving for the redundant braking technology.
Redundant steering is also a key technology for automated driving and Bosch is leading in this area. At NAIAS 2017, Bosch introduced its Electric Power Steering (EPS) system with fail-operational function. The system, which enables […]
