PLC-based Flow Monitoring System

This Bachelor thesis is focused on designing and implementing a PLC-based flow monitoring system. The system is built on B&R Industrial Automation GmbH devices (especially on a PLC and touch screen combination named Power Panel C70) and ifm electronic GmbH flow sensors (the supported types are SD8000, SD9000, SM2000 and SM9004). System requirements are described in the first part of the thesis as well as the application and visualization concept. The technical equipment and the implementation of the PLC application and visualization are presented in the second part of the thesis. The application was developed in the B&R Automation Studio (4.3.4.121 SP version) using the Structured text programming language (according to the IEC 61131-3 standard). Visual Components (4.34.1 version) tool was used to generate the visualization. All system requirements were met and the system itself is currently in use by the Milacron company in Polička to monitor and record the consumption of compressed air and cooling water of their plastic processing machines
