Automation of sorting line model using programmable logic controller S7-1500 in programming language FBD

U završnom radu obrađen je postupak automatizacije modela trake za obradu predmeta pomoću programirljivog logičkog kontrolera Simatic S7-1500, tvrtke Siemens. Najprije je opisana sama struktura PLC-a, njegov programski ciklus te načini adresiranja memorijski lokacija. Zatim je dan uvid u hardversku konfiguraciju PLC-a koji se koristi za ostvarenje algoritma upravljanja. Konfiguracija se sastoji od CPU modula, modula napajanja, modula s 32 digitalna ulaza te modula s 32 digitalna izlaza. Algoritam za upravljanje modelom izrađen je u Siemensovom programskom alatu TIA Portal. Funkcija koju algoritam upravljanja treba obavljati je stavljanje predmeta na traku modela pomoću pokretne ruke, zatim transport predmeta po traki do prvog obradnog mehanizma gdje se traka zaustavlja i mehanizam obrađuje predmet. Nakon završetka obrade predmet je potrebno transportira trakom do drugog obradnog mehanizma gdje se traka ponovno zaustavlja. Radni mehanizam zatim obrađuje predmet koji se nakon obrade transportira na kraja trake. Algoritam također broji ukupni broj obrađenih predmeta čiji broj je kasnije moguće prikazati operateru pogona.This bachelor thesis elaborates the automatization process of the line model for object processing using Siemens Simatic S7-1500 programmable logic controller. First there is given a view into the structure of a programmable logic controller, its program cycle and the way of addressing memory locations. After that the hardware configuration, of the controller used to realize the control algorithm, is described. The configuration consists of a CPU module, a power module, a digital module with 32 inputs and a digital module with 32 outputs. The control algorithm is created in Siemens programming toll TIA Portal. The function that the control algorithm has to preform is to put objects on the transport line using a moving hand. After the object is on the transport line, it has to be transported to the first processing mechanism where the transport line is stopped and the processing of the object starts. When the mechanism finishes processing, the object is transported to the second processing mechanism where the transport line stops again and the second processing of the object starts. After the processing is finished the object is transported to the end of the transport line. The algorithm has to count processed objects and the number is later available to the plant operator
