CODESYS – the universal tool for PLC programming

Abstract

The paper presents CoDeSys as a universal tool for PLC programming in compliance with the IEC-61131-3 standard. In the introduction to the paper, the expectations that should be placed on the PLC programming environment were defined. Then CoDeSys has been characterized, emphasizing its independence from the PLC manufacturer and the possibility of writing, simulating and visualizing programs without the need to own a physical device. The next part briefly discusses how to prepare the program and how to simulate and visualize its operation. In conclusion, an extremely current in the era of the COVID pandemic feature of the CoDeSys environment was pointed out, which is the possibility of its easy use for remote teaching of PLC programming.
