The project carried out a complete replacement of the automation for the control of three switchgears in the factory (TS17, TS Energana and TS Šećerana) with distributed PLC configurations manufactured by SIEMENS. It is possible to manage all systems from one place, from the dispatch center of the factory. In addition to all standard features, the SCADA application also exchanges data with the factory’s superior DCS system and several other existing subsystems.
