INDUSTRIAL AUTOMATION
Academic Year 2022/2023 - Teacher: Giuseppe NUNNARIExpected Learning Outcomes
1. Knowledge and understanding. Students will learn to:
- Represent Discrete Event Systems (DES) by means of Petri nets.
- Analyze the structural properties of a model represented by Petri nets and its control through the approach of monitor places.
- Know the architecture of Programmable Logic Controllers (PLC).
- Know the programming languages of programmable logic controllers (PLCs) as described in the IEC 61131-3 standard.
- Know the structure of computer networks for industrial automation and systems for supervision and data acquisition (SCADA).
Applying knowledge and understanding. Students will be able to:
- represent, analyze and simulate the properties of discrete event systems (DES).
- code the software for PLC and debugging, both through the use of simulators and by operating in the laboratory directly on the HW devices.
3. Autonomy of judgment. Students will be able to judge the strengths and weaknesses of techniques in use in the field of Industrial Automation.
4. Communication skills. Students will be able to illustrate the techniques learned in the course, interact in teams and collaborate with industry experts..
5. Learning skills. Students will be able to autonomously extend their knowledge of the techniques used in the field of industrial automation, drawing on the vast literature available in the field.
Course Structure
- The course takes place through lectures and experiences in the laboratory. To each course topic is devoted an adequate amount of time in the laboratory experiences which reinforce the learning. In the laboratory, students will use both software tool and hardware devices to learn the analysis of discrete event systems and PLC programming.
- Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Required Prerequisites

Learning Assessment
Learning Assessment Procedures
The exam consists of a written and an oral test. The test concerns two aspects: 1) The analysis and control of discrete event systems using Petri nets, 2) The implementation of a control program for an assigned industrial process using the languages learned in the course. The program can be written using a laptop if available to the student. Examples of the written tests assigned can be downloaded by registered students on the website dedicated to the course within the Teams portal (https://teams.microsoft.com). The oral test consists of a discussion of the written test and an interview on the topics presented during the lectures. The student is expected to draw up a report certifying the tests performed during the laboratory. Sample reports will be available in advance on the Teams course website.
Verification of learning can also be carried out electronically, should the conditions require it.
