Course detail
Distributed Systems and Networks
FEKT-MDSSAcad. year: 2017/2018
Subject deals with modern problems in automation e.g. with distributed control systems. The main attention is given on the communication subsystem that creates the backbone of these systems. Students obtain practical experiences with industrial communication systems PROFIBUS, PROFINET, ETHERNET/IP, DeviceNet, RIO. Students obtain a deep and large view of open system interconnection, communication standards, proprietary communication systems and their implementation. Next part of the subject deals with distributed control systems DCS from the first control level as many as the operator level.

Planned learning activities and teaching methods
Assesment methods and criteria linked to learning outcomes
upto 70 (50+20) points from examination
Examination has two compulsary parts - written part 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.
