TIA PORTAL-PLC PROFINET NETWORK

Cilj ovog rada je bio napraviti sustav upravljanja motorima iz kontrolnog centra primjenom triju PLC-a i HMI sučelja. HMI sučelje izrađeno je u TIA Portalu v15 na WinCC RT Advanced platformi. HMI sučeljem se upravlja sa tri asinkrona motora pri čemu je svaki od njih preko frekvencijskog pretvarača MicroMaster 420 spojen na zasebnu PLC stanicu. Komunikacija između PLC stanica je ostvarena u PROFINET protokolu. U radu je također objašnjena konfiguracija PLC stanica, komunikacija, izrada programskih blokova i vizualizacija rada sustava. U sklopu vizualizacije sustava omogućen je prikaz statusa rada motora, te analognih mjernih veličina i alarma.The goal of this paper was to create a motor control system using three PLCs and HMI interface. The HMI interface was developed in TIA Portal v15 on the WinCC RT Advanced platform. The HMI interface controls three asynchronous motors, each of which is connected to a separate PLC station via a MicroMaster 420 frequency converter. Communication between PLC stations is realized in the PROFINET protocol. The paper also explains the configuration of PLC stations, communication, creation of program blocks and visualization of system operation. As part of the visualization of the system, it is possible to display the status of engine operation, as well as analog measuring quantities and alarms
