Tank level control using programmable logic controller

Tema diplomskog rada je izrada upravljačkog sustava za regulaciju procesa uskladištenja tekućine u spremniku pomoću PLC-a. Unutar programa MATLAB izvršen je simulacija programa na temelju matematičkog modela, te su prikazani dobiveni odzivi. Unutar softvera TIA Portal odabran je PLC, izvršeno spajanje s uređajima koji omogućuju simulaciju, te je izrađeno HMI sučenje za regulaciju procesom. Napisan je kod procesa u FBD, te je svaka mreža koda detaljno objašnjena. Prikazani su i objašnjeni dobiveni odzivi regulacijskog kruga.The main purpose of this paper is to develop a control system for water regulation in the tank using a PLC program. Thus, with the help of the MATLAB program, a program simulation based on a mathematical model was performed and the obtained responses are presented in the paper. Furthermore, within the TIA Portal software, the appropriate PLC was selected and the connection with the devices that enable this simulation was performed, users are enabled to manage this process using the HMI interface. Based on this, it was written a FBD process code and all the networks are extensively explained
