Sistemas de Comunicaçao Industrial

Knowledge of digital systems and digital networks

Teaching method: presential.

The methodology adopted includes expository methods to explain fundamental concepts to students, illustrated with application examples. Classes will also include exercises to consolidate knowledge and practices.

In more practical classes, students will work in groups to carry out various implementation and simulation tasks on industrial communication technologies, based on the equipment and software available.

This course aims to provide students with skills related to industrial communication systems. The course presents and analyzes the main protocols used in industrial networks and the appropriate network cabling for these environments, preparing students for the design, implementation, and management of wired and wireless networks in industrial automation systems.

At the end of this course, students should have the following skills and knowledge:

• Know the existing solutions for industrial communication networks  (eg Profinet, Profibus and Modbus TCP/RTU)
• Know, select and implement emerging communication solutions, namely wireless (eg 6LowPAN, LoRAWAN, WirelessHART)
• Integrate emerging communication solutions with existing communication solutions (Industry 4.0).
