The aim of the course is to introduce industrial automation, basic elements of automation equipment, measuring converters, relays, actuators, automation circuits, programmable logic controllers (PLC), their use, structure, programming, connection to the controlled object. Programming languages of PLC are acquired: ladder diagrams, structured text, block diagrams, development of control algorithms. PLC connection, input and output signals, PLC control visualization on HMI, remote control via GSM and LAN, and SCADA control system are studied.
1. Knowledge - principles, basic elements, control algorithms and circuits of industrial automation. Knows the origin, construction, application possibilities and programming of programmable logic controllers, connection to a controlled object - practical exercises and tests;
2. Skills - to use PLC, program it and connect it, use automatic control circuits and algorithms - practical exercises;
3. Competence - ability to choose PLC, create automatic control schemes using PLC – practical exercises.

• All practical exercises must be completed and defended. The defence of practical exercises involves the presentation of the protocol to the lecturer and the answers to the thematic questions.
• All test papers must be written successfully.
• Exam must be passed
Students' independent work consists of literature studies, preparation for practical exercises and completing of practical exercises protocols.
The final grade is the weighted mean of the all the tests (50%) and exam (50%). Each test consists of theoretical and practical parts. The student can successfully pass the test if at least 50 % of the test questions are answered correctly and a practically working program is created according to the given assignment. Exam is theoretical in electronic studies.
