Aims

The aim of the subject is education and training in programmable logic controllers PLC that are frequently used for control of machines, production lines and technological processes. Students make equating with architecture and circuits of PLC, basic features and modules. They will be able to develop programs in simple programming languages of PLCs (Ladder, Instruction list, FBD) as well as in languages of sequential processes (SFC, Grafcet). They will be informed about possibilities to interconnect PLCs by means of serial communication buses.
