This bachelor thesis deals with the integration of the ABB ACS880 frequency converter into the AC500 PLC control system via the PROFINET industrial bus. The thesis analyzes the capabilities of the FPNO-21 communication module, focusing on cyclic and acyclic data exchange. The core of the work is the implementation of a comprehensive software solution in the Automation Builder environment. Developed function blocks ensure standard drive control, advanced fault diagnostics, and the reading of service data using DPV1 acyclic services. Furthermore, a custom software analyzer is implemented to measure application latency and network stability (jitter). The final part of the thesis verifies the functionality on real hardware, including system responses to critical fault states and communication failures.
