Department of Control Engineering

Synopsis:

The subject Programmable Logic Controllers deals with structure and parameters of programmable logical controllers (PLC), their configuration and programming. Students find out different ways of PLC's programming. We compare hardware and software solution of PLC's from leading producers. The main emphasis is put especially on the skills in application of programmable controllers for solving standard technical tasks.
