87269 - Automation Software and Design Patterns M

Academic Year 2022/2023

  • Docente: Gianluca Palli
  • Credits: 6
  • SSD: ING-INF/04
  • Language: English
  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: Second cycle degree programme (LM) in Automation Engineering (cod. 8891)

Learning outcomes

The course aims to provide a rational view of the main principles, methodological issues, design patterns and integrated development environments involved in the implementation of modern automation systems. The course will focus on model driven generation of Finite State Machines, connection layers based on Input and Output Bridges, Generic Devices and Generic Axes and fault managment systems. At the end of the course students are able to master design aspects of advanced software architectures for complex automated machines, defining models and flexible solutions for common problems independently from the machine and hardware architecture.
