In the task students develop a factory digital twin
• Prepare the architecture of the production line (conveyor belt, sensors, actuators and control systems). • Simulate the production line (Factory IO allows you to simulate the process without the connection to the real world. We can predict failures, estimate the production time etc.).
Read MoreBased on simulation each team connects its own part of the production line to the real world. Factory IO allows you to connect the virtual world to a real world. In real world we will use PLC (e.g. Simatic 1200) and some sensors and actuators, that will be connected to it. This allows us to input data from the real world into the digital twin and use the results from the digital twin to control the real world. During the meeting in Ljubljana commissioning teams (partners) assemble parts on the common physical production line.

Students program in various programming languages such as c, c++, SCL, ladder logic, php, javascript, html, SQL for data management, python, CSS, ... Many a graduation thesis is a finished product or service that would have its place in a competitive market environment.

Depending on the position of the installed sensor, we can easily determine the height of the object.
The object moves along the conveyor belt and when it reaches a place with a built-in sensor, the control electronics detects its height. Depending on the previous requirements, the control program can then pass the information on to processing for controlling the actuators.
The production process can be controlled virtually via a computer or directly in production.
For the possibility of managing the production process both directly in production and via the virtual world, care must be taken to ensure that the signals are not intertwined. For example, if a button is pressed on a switch cabinet in production, this signal must also be processed correctly in the virtual world. The priority of individual signals is also important for proper operation.
The correct placement of the sensors is important for the reliable operation of the device.
To determine the height or width of a certain object on the conveyor belt, not only the type of sensors is critical, but also the position of the installed sensors. Of course, they must be installed in such places that they do not hinder the basic production process, which is sometimes difficult to ensure.
