Course detail

Communication Systems in Industrial Automation

FEKT-MPC-KTAAcad. year: 2020/2021

The course focuses on communication subsystems in the field of automation technology, ie distributed control systems. Practical experience will be gained by students with RS-485 industrial communication systems as a typical representative of bus technology. Thei will also get familiar with selected Ethernet, Internet and wireless networks. Students will deepen their knowledge about open communications, standards and quasi-standards of industrial networks and their implementation with an emphasis on lower protocol layers. Students are also acquainted with the basic aspects of risk analysis as a basis for functional safety and cybersecurity.

Learning outcomes of the course unit

After completition of the course students will be able to>
- describe layers of the OSI model,
- explain "communication in real time",
- list and briefly describe some of the deterministic communication solutions,
- describe most distinguishing features of RS-232, RS-485, CAN, Modbus, Ethernet and Industrial Ethernet,
- explain basic principles of functional safety,
- briefly describe bacis security building blocks,
- discuss advantages and disadvantages of selected communication technologies,
- provide qualified guess on relevance of functional safety standards for a given application,
- based on given requirements select suitable communication technology for a given task.

Prerequisites

Student who enrolls this course needs to be able to explain basic principles from physics and electronics related transmission lines and their loading (resistance, capacitance, inductance, impedance) and issues related to carrying of signals over the transmission lines; analyze simple electronic circuits with passive components and transistors; discuss basic issues in the field of probability and statistics; calculate probabilities of serial and parallel combination of components. In general electrical/electronic bachelor degree konowledge is expected, moreover it is recommended either to have previous experience with PLC programming.

Planned learning activities and teaching methods

Techning methods include lectures and practical laboratories.

Assesment methods and criteria linked to learning outcomes

upto 30 points from laboratories
upto 70 (50+20) points from examination.
Examination has two compulsary parts - written part (5 questions 10 point each) and verbal part.
To qualify for verbal part it is necessary to gain at least 24 points from the written one, no two questions from the written part can be evaluated as zero. To pass the exam it is necessary to gain at least 10 point in the verbal part.
Exam is focused to evaluate general knowledge in the field of serial communication technologies, fieldbuses, functional safety and security.
