摘要
In the paper a structure of PLC and PLC programming are described and explained step by step. The authors start description from simple micro-programmed digital circuit and next developing it with program counter, instruction decoder, input/output modules, counter and timer modules, internal busses and arithmetic logic unit explain an operation of the PLC and the idea of programming and utilization of such devices. A few examples of considered PLC simple applications are presented.
