Elevator system simulation model realized in programmable logic controller

Tema rada bila je simulacija rada sustava tri dizala na četiri kata. Simulacija je provedena u programskom paketu TIA Portal pomoću grafičkog HMI sučelja. Korišteni ulazni signali, odnosno ulazni uređaji su tipkala unutar i izvan lifta, dok su izlazni signali svijetlosni indikatori pomaka dizala te signali za pokretanje motora. Sustav rada dizala može se proširiti na rad dizala na više od četiri kata korišenjem jednake logike. Simulacija je provedena preko Siemens SINAMIC S7-1200 programibilnog logičkog kontrolera. S manjim promjenama u sintaksi, program je moguće simulirati i na ostalim serijama PLC-a.The topic of this diploma word is to simulate the system of three elevators on four floors. The simulation was carried out in the TIA Portal aplication pack using the graphical HMI interface. Used input signals are push buttons inside and outside of an elevator, while the output signals are luminous indicators and signals for motor control. This system of elevators can be extended to work on elevators with more floors using same logic. The simulation was performed using Siemens SIMATIC S7-1200 programmable logic controler. With minor changes in syntax, the program can be simulated on other series of PLC-s
