Abstract

SIMATIC PCS 7 je procesni upravljački sustav najviše korišten za projektiranje distribuiranih sustava upravljanja. Projektiran je dio postrojenja za neutralizaciju otpadnih voda čiji se proces sastoji od dva redundantna spremnika za prikupljanje otpadne vode, sustava ispumpavanja vode iz istih spremnika, spremnika sa lužinom i kiselinom te dva spremnika za neutralizaciju. PCS 7 omogućava hijerarhijsku raspodjelu svih navedenih jedinica sustava te njihovih komponenti. Upotrebom CFC-ova i... More njihovih blokova iz standardnih biblioteka konfigurirana je funkcionalnost komponenti (ventila, motora, senzora), kao i onih pomoćnih (tajmera, brojača itd.). Pomoću SFC-ova projektirano je sekvencijalno izvođenje zadanih procesa upotrebom blokova koraka i tranzicija. Vizualizacijski prikaz rađen je u WinCC Explorer-u pomoću prethodno definiranih procesnih slika i slikama njihovih komponenti. Za izradu realnog simulacijskog modela korištena je SIMIT simulacijska platforma koja omogućava virtualno puštanje u pogon korištenjem blokova signala, modela stvarnih komponenti i matematičkih funkcija.

Abstract (english)

SIMATIC PCS 7 is process control system mostly used to design distributed control systems. Designed part of the plant is a part where neutralization of wastewater takes place, whose process consists of two redundant wastewater tanks, a pumping system of the same tanks, lye and acid tanks, and two neutralization tanks. PCS 7 enables the hierarchical distribution of all of the above system units and their components. By using CFCs and their blocks from standard libraries, the... More functionality of components (valves, motors, sensors), as well as auxiliary objects (timers, counters, etc.), is configured. SFCs are designed to sequentially perform the processes using step and transition blocks. The visualization display was made in WinCC Explorer using predefined process pictures and images of their components. To create a real simulation model, a SIMIT simulation platform was used, which enables virtual commissioning using signal blocks, real component models and mathematical functions. Less
