The digitally driven change in industrial production requires stronger networking and more intelligent information at all levels of production. With fischertechnik Learning Factory 4.0, these digitization activities can be simulated, learned and applied on a small scale before they are implemented on a large scale. A highly flexible, modular as well as cost-effective and robust training and simulation model which can be used in an extremely useful way.
The fischertechnik learning environment is used for learning and understanding industry 4.0 applications in vocational school and training and for use in research, teaching and development at universities, in companies and IT departments. The simulation depicts the ordering process, the production process and the delivery process in digitized and networked process steps.
The following topics can be addressed with fischertechnik Training Factory Industry 4.0:
• Training and simulation on a realistic production image
• Deepening learning through haptic comprehension
• Optical and sensory applications
• Digital traceability with NFC/RFID
• Customer-specific production in batch size 1
• Integrated cloud connection, control via smart devices
• Use and operation of dashboards
• Web-based remote monitoring
• Linking of production and disposition data
• Connection of upstream/downstream logistics processes
• High-bay warehouse operates according to FIFO industry standard
• Sample program as structured text (ST) for Siemens PLC S7-1500 already included, custom program creation by end-user is also possible
The Training Factory Industry 4.0 24V is controlled by a PLC (brand independent, not included in the scope of delivery) and comes with a ready-made sample program (as Structured Text, ST). The sample program is based on a Siemens S7-1500 (details at www.fischertechnik.de/simulation). The newly developed 24V adapter boards as interface to the PLC are available in the Training Factory Industry 4.0 pre-assembled, and are connected to the PLC via terminals. Among other things, this latest generation of adapter boards allows
• the encoder motors to be controlled in speed via PWM
• the use of push/pull output stages for phototransistors and buttons
A fischertechnik TXT controller is also installed in the Training Factory Industry 4.0 24V. This is supplied with power via the adapter board and provides the connection to the fischertechnik cloud. The TXT Controller also communicates in MQTT to the IoT gateway (Raspberry Pi) which in turn translates in OPC-UA to the PLC controller. This also allows the 9V based components on this model—such as the environmental sensor, the USB camera, the brightness sensor, and the NFC reader-- to communicate via the MQTT interface and read out from the PLC Another interesting feature--which is another function of the IoT gateway--is the possibility of an optional connection to a separate cloud. As such, Training Factory Industry 4.0 offers maximum flexibility for the end user.
two dashboards, raspberry pi, Node-Red
The fischertechnik dashboard in the cloud can be called and operated via mobile devices such as tablet and smartphone as well as on laptop and PC. Additionally, a local dashboard, created with Node-RED, is available on the Raspberry Pi (IOT gateway) is implemented, and custom dashboards can also be created via Node-RED. The dashboards included in Training Factory Industry 4.0 enable the display of platforms from three different perspectives:
• Customer view
• Supplier view
• Production view
The connection to the fischertechnik cloud is established via the WLAN router which is integrated in the learning factory. The use of the Chrome or Firefox web browsers is recommended. The cloud can be used via a personal access which is created once. The servers of the cloud are located in Germany and ensure that the strict European requirements apply for the storage of data. Personal data is protected in an account with password access, which uses the very secure "OAuth2" industry standard. All data sent to the cloud is encrypted with certificates (https standard).
The PLC sample program for controlling the fischertechnik Training Factory Industry 4.0 was created for use with a Siemens S7-1500 and can be found at Github, where it can be used and downloaded free of charge: https://github.com/fischertechnik
Of course, the fischertechnik Training Factory Industry 4.0 can also be used with many other popular PLC models and brands, and individual solutions can be programmed and implemented by the end-user. Please note that it may be necessary to make small adjustments to the sample program, which are to be implemented independently.
