Automation of line model for sorting by sample height using programmable logic controller S7-1500 in programming language SCL

Glavni zadatak bio je napraviti programsko rješenje za dani model linije za sortiranje predmeta po visini koristeći Siemensov PLC S7-1500. U radu su ukratko objašnjene glavne osobine PLC-a te njegov način rada, arhitekturu korištenog te potom počeo sa glavnim dijelom zadatka. Rješenje je izrađeno u programskom alatu TIA portal koji obuhvaća Step7 i WINCC Siemensove programe. Za realizaciju rješenja koristio sam programski jezik SCL koji najviše sintaksno sliči Pascalu. Izrađeni HMI je poprilično jednostavan, no služi svojoj glavnoj namjeni-upravljanjem postrojenjem i brojanjem broja sortiranih predmeta u automatskom načinu rada.Main task of this thesis was to programme a solution for a given model of line for sorting the objects by their size using the Siemens S7-1500 PLC. I shortly explained PLC's working cycle , the architecture of used PLC, after which i started solving the main part of the problem. The solution was made in toolkit software TIA portal, developed by Siemens, which is consisted of Step7 and WINCC programmes. The programme code was written in Structured Control Language (SCL), which is based on well known high end programming language Pascal. HMI is simple, but convenient, doing the tasks of process control and counting the amount of sorted object in automatic work mode
