Computers and Processes
Knowledge and skills necessary for design, deployment and maintenance of process computers and systems. Process computers software development and implementation. Understanding of interdisciplinary approach to process control problems, through teamwork and cooperation.
- list important characteristics of process computers
- apply correct principles to computer-process interaction
- explain demands put on real-time systems
- choose appropriate micro-controller based on project demands
- choose appropriate communication protocols
- describe industrial control, supervisory and data acquisition systems
- employ important embedded development concepts
- identify role and organization of computers in a process
Forms of Teaching
The lecturer explains and illustrates topics. Students are encouraged to engage in discussion.Exams
Student take short exams during lectures. Students also take midterm and final exams. Final exam is both written and oral.Experiments
During lectures, the lecturer exhibits hardware and software demos to illustrate points discussed in lecture.Consultations
Lecturers and teaching assistants are available for consult during office hours or by appointment.Programming Exercises
Students are required to solve practical problems using concepts discussed on lectures. They do so by autonomously coding in various programming languages (assembly, C, ladder diagrams) using skills and knowledge acquired throughout their studies.
