Flexibility despite a high degree of automation is one of the most important challenges in manufacturing companies. It demands the integration and networking of different controls in a complex automation system. This is complicated by the huge variety of programming software available. Differences in user interface, functionality and command sets cause confusion and make mistakes more likely. CoDeSys – a tried and tested, globally-introduced hardware-independent software from 3S offers a Controller Development System according to the IEC 61131-3 with all defined programming languages independent of the hardware manufacturer. This training demystifies CoDeSys and gives participants confidence in using it.
