Automation of car wash model using programmable logic controller S7-1500 in FBD programming language

U ovom završnom radu izrađen je program za automatizaciju modela autopraonice te vizualizacijsko sučelje kojim se može upravljati ciklusom rada modela autopraonice. Model je upravljan pomoću PLC-a Siemens S7-1500 CPU 1516-3 PN/DP, a povezana sa PLC-om preko PROFIBUS kabela i ET200S ulazno/izlaznog modula. HMI sučelje kojim se upravlja i nadzire rad modela autopraonice povezano je sa PLC-om pomoću PROFINET komunikacije. Programsko rješenje algoritma upravljanja i vizualizacije razvijeno je pomoću programskog paketa TIA portal v14 koristeći funkcijski blokovski dijagram (FBD). U okviru programskog paketa TIA portal korišten je alat STEP 7 za razvoj programskog rješenja te alat WINCC Professional za razvoj vizualizacije. U završnom radu opisane su komponente od kojih se sustav sastoji, kao i princip rada. Opisano je programsko sučelje koje se koristi u završnom radu te rad algoritma za upravljanje automatiziranom autopraonicom.Within this final assignment, program for automation of carwash model and human-machine were made. Carwash model is controlled by Siemens S7-1500 CPU 1516-3 PN/DP programmable logical controller and is connected with the PLC by PROFIBUS cable and ET200S input/output module. HMI is connected with the PLC by an ethernet cable using PROFINET communication standard. Program solution for this task was made by using Siemens TIA portal program environment and was implemented by using function block diagram (FBD). STEP 7 and WinCC Professional were used within TIA portal. Furthermore, components used in this task were described as well as the principle of work. Program environment used was also described, so as the algorithm that is made for automation of carwash model
