The IoT in practice trail demonstrates the performance of databased apps on the way to autonomous manufacturing. It focuses on customized analysis and diagnosis applications for engineers and machine operators. With the help of these digital-assistants vast amounts of raw data is permanently processed throughout the whole process chain. This data helps to simplify the users working processes by using automatically computed recommendations for action and also helps to reduce resource consumptions, machine downtime, rejects or critical stress situations.
The core of the trail is the direct interchange with expert users of real process chains in lightweight constructions and plastics processing, which serve to make the benefits of IoT tangible for the participants.
All demonstrating sites are equipped with the IoT apps based on the IoT-Dashboard Detact™. They provide an overall data consolidation and analysis of process-, quality- and material-data retrieved from distributed and heterogeneous data sources.
Visitors will witness and understand how a global view of a certain process chain is created due to IoT and which methods make process chains mathematically describable. They will also learn how mathematics – encapsulated in the IoT apps – gets usable for engineers to quantify interactions within the process chain in order to optimize the processes. The participants can experience each showcase at selected facilities, gain valuable inspirations concerning the usage of IoT in their own factory and engage in cooperative exchange and discussion on the digitizing strategy of manufacturing processes.

Normally, process managers have a particular interest in process data in the event of problems or when optimum setup parameters are required to commission a new product. And so the whole process chain is monitored and more and more data is measured and recorded. But during the processing time the potential of the permanently recorded production data is lost. Furthermore, due to the data’s distribution, amount and heterogeneity and originating from different sources (e.g. machine control units, sensors, databases or up to handwritten protocols) there is a high effort or it’s even impossible to connect data in order to detect parameter correlations throughout the entire process. However, the IoT in practice trail reveals what it means to never lose track of your data but learn from it in the running process. The aim of it is to accomplish a recording, processing and evaluation of data streams assisted by a high level of automation – or to put it otherwise: IoT for the production industry.
In part 1 of the trails (Teaser) the participant gets an understanding of the methods and the architecture of the IoT platform. With real-life examples, complex process chain models are developed and methods of automatic analyzing services plus connection techniques for connecting external data sources are introduced. It’s also illustrated in which scenarios IoT platforms can be typically applied in production and which ambitions are aimed to achieve by the user group. In addition, the requirements are specified regarding the data basis and the necessary expert skills in analysis methods.
On the other hand the potential for statistically and technologically data services will be examined based on sample data of the participants. Especially the estimation, if existing technological problems can be processed with the available and potentially recordable process data, is in focus. This includes the following steps:
- collection and optionally preselection of potentially production processes (selection of facility systems; which steps of the manufacturing process chain should be examined)
- description of the actual technological situation and specification of the technological type of problem
- predefinition of the performance measurement in the end of the project: economic criteria, requests, estimation of the feasibility, rating of the potential portability to other processes
- investigating the technological framework of the data collection (machine connection, manual gathering, data formats, etc.)
- estimating expectable project results, e.g. increased controllability (and its probabilities) as well as optimization potential and its valuation
- surveying and evaluating project risks
As a result, the participant is able to evaluate the capability of a data driven approach for its individual issues. In part 2 of the trails the participant obtains information about how IoT applications work and how they can be customized or completely newly developed to meet the very own needs. Symate will provide knowledge regarding the setup of the main settings of an IoT platform: mapping of the users and devices; configuration of parameters as well as for the fundamental handling on the basis of Detact™: data recording and processing functions, process chain modelling functions, parameter selection and prioritizing, plus process data analysis and the basics of complex analysis such as regression, sensitivity analysis, correlation analysis.
Based on that, the participant will face real IoT scenarios in the production environment. The different stations of the trail are structured according to various stages in the production technology as follows:
- Smart Ramp-Up (Demonstrators ILK, LZS)
- Smart Diagnostics (Demonstrators DGH, JKL)
- Smart Control (Demonstrator FEP)
In sequentially ordered showcases the different use cases, significant for technologists, process engineers, production managers or maintainer, will be demonstrated. The practicability of IoT apps for the daily work of the prospective user group is open to discussion with the respective practice partner. To make IoT projects calculable to the trails participants, the demonstrated benefits can be transferred to the specifics of the visitor’s peculiar process chains. Such as:
- reducing rejects due to gained insights via IoT apps,
- improvement of availability, quality and performance (e.g.: increasing OEE by >10%),
- discharge of routine tasks in root cause analysis by up to 90%,
- increased customer satisfaction due to individual component notes for customers,
- minimized down times of the process chain due to recognizing potential disruptive factors before occurrence.

Typical basic installations start with up to 3 data sources and can be expanded to productive systems with additional data sources or with increased data capacity. Expensive and long-term implementation projects with large project teams are prevented, instead the lean and flexible approach of Detact™ establishes a usage of data amounts which is incoming from the production process anyway as well as an immediate supply of usable results.
Finally, the participants are also introduced to funding opportunities provisioned by SAB and BMWi suitable for small and medium-sized enterprises.
