Abstract.
The paper deals with SCADA system for controlling and monitoring mechatronic systems which are controlled by programmable logical controllers (PLC) and connected into local area network (LAN). Application OPC Easy Server is used to access PLC, software package LabView is used to create graphical control environment, and Festo software FST 4.10 is used to program PLC. Each PLC has its own unique IP address whereas each input and output PLC signal has its own local address. The realized system enables graphical interface for control and monitoring of physical values of the system processes and parameters. A big advantage of the solution presented in this paper is the possibility to control systems which are realized with different types of PLCs and with PLCs made by different producers, possibility to control systems in the local area network as well as control and monitoring of mechatronic systems by Internet regardless of geographic position of the operator and process.
Key Words:
control, mechatronic system, PLC, OPC server, TCP/IP, Internet.
FORMIRANJE SCADA SISTEMA ZASNOVANOG NA OPC SERVER I LABVIEW ZA UPRAVLJANJE MEHATRONSKIM SISTEMIMA
U ovom radu prezentovan je SCADA sistem za kontrolu i nadzor mehatronskih sistema, koji su upravljani programibilnim logičkim kontrolerima (PLC) i povezani u lokalnu računarsku mrežu (LAN). Za pristup PLC-u koristi se aplikacija OPC EasyServer, za kreiranje grafičkog nadzorno upravljačkog okruženja softverski paket LabView i za programiranje PLC-a Festov softver FST 4.10. Svaki od PLC-a ima svoju jedinstvenu IP adresu, a svaki od ulaznih i izlaznih singala PLC-a, jedinstvenu lokalnu adresu. Realizovani sistem omogućava grafički interfejs za upravljanje, nadzor i kontrolu željenih fizičkih veličina procesa i parametara sistema. Velika prednost predstavljenog rešenja je mogućnost upravljanje sistemima realizovanih sa različitim tipovima PLC-a, PLC-a različitih proizvođača, upravljanje u lokalnoj računarskoj mreži, kao i upravljanje i nadzor mehatronskim sistemima preko Interneta, bez obzira na geografsku lokaciju operatera i procesa.
