Course detail
Programmable Controller Systems (PLC)
FSI-VPL Acad. year: 2023/2024 Winter semester
The course extends the Automation and Control Equipment subjects with topics related to structure, parameters, programming and capabilities of modern industrial contol systems. The emphasis is placed mainly on the operation of programmable logical controllers (PLC) and complex multitask systems, in conjunction with the controlled I/O technology, drives, user interfaces, and and its direct integration into the "Industry 4.0" framework.

Aims
The aim of the subject is to introduce capabilities offered by programmable logical controlles (PLC) and modern control systems, as well as understanding of typical develeloper activities, from elementary definition of the hardware, work with process variables, principles and advantages of cyclic multitasking, through graphical user interfaces, up to the principles of State Machine programming in process control and drive management, all in simple laboratory applications.
The subject brings capability of practical orientation in engineering applications which require use of programmable control systems, selection of proper automation hardware, as well as development of control software for the related technological tasks.
