diplomsko delo
Abstract
Cilj naloge je narediti nadzorni sistem, ki vključuje uporabo programirljivega logičnega
krmilnika (PLK) (ang. programmable logic controller - PLC) in frekvenčnega pretvornika
za krmiljenje asinhronskega motorja. Nadzorni sistem bo omogočal spremljanje stanja
naprav v sistemu, spreminjanje parametrov delovanja motorjev, preklapljanje med
ročnim in avtomatskim načinom delovanja in pa odkrivanje morebitnih napak v sistemu.
V diplomski nalogi so v prvem delu opisane vse komponente sistema, ki je narejen na
demonstracijskem panelu. Predstavljeno je, kako se vzpostavi povezava med PLK-jem
znamke Siemens in frekvenčnim pretvornikom proizvajalca ABB. Povezava je
vzpostavljena preko protokolov PROFIBUS in PROFINET, ki sta med najpogosteje
uporabljenimi komunikacijskimi protokoli v industriji.
V nadaljevanju je opisan primer uporabe frekvenčnega pretvornika in upravljanje sistema
preko nazornega sistema Siemens SIMATIC WinCC V7. Nadzorni sistem operaterju
omogoča komunikacijo s strojem in s tem nadzor nad procesom. Poleg tega pa tudi hrani
in obdeluje podatke in sporoča sistemske napake. V diplomski nalogi je prikazno, kako se
uvozi spremenljivke s krmilnika v nadzorni sistem Siemens SIMATIC WinCC V7, kako se
barva ikone glede na vrednosti spremenljivk sistema (stanje sistema), odpiranje oken za
upravljanje naprave in prikaz alarmov.
Menim da je naloga uspela, saj sistem izpolnjuje zastavljene zahteve delovanja, ki si bile
navedene v poglavju 2.1.V šestem poglavju lahko vidimo da se ikone pravilno barvajo
glede na stanje sistema in da nas v primeru napake nazorni sistem obvesti.
Naloga je primerna za učenje začetnikov v avtomatiki, saj opisuje izdelavo nadzornega
sistema, ki vključuje uporabo PLK-ja in frekvenčnega pretvornika za krmiljenje
asinhronskega motorja.

SCADA system and induction-motor control |
Secondary abstract: |
The aim of the task is to make a control system that includes the use of a programmable
logic controller (PLC) and a frequency converter to control an induction motor. The
control system will enable monitoring of the condition of devices in the system,
changing the parameters of engine operation, switching between manual and automatic
mode and detecting possible faults in the system.
In the first part, the diploma thesis describes all the components of the system made on
the demonstration panel. It is presented how to establish a connection between a
Siemens PLC and an ABB frequency converter. The connection is established via the
PROFIBUS and PROFINET protocols, which are among the most commonly used
communication protocols in the industry.
The following is an example of using a frequency converter and operating the system via
the Siemens SIMATIC WinCC V7 demonstration system. The control system allows the
operator to communicate with the machine and thus control the process. In addition, it
also stores and processes data and reports system errors. The diploma thesis shows
how to import variables from the controller into the Siemens SIMATIC WinCC V7 control
system, how to color the icon according to the values of system variables (system
status), open device management windows and display alarms.
I think that the task was successful, because the system meets the set operating
requirements, which were stated in section 2.1. In the sixth chapter we can see that the
icons are colored correctly according to the state of the system and that in case of error
the visual system informs us.
The task is suitable for beginners to learn in automation, as it describes the construction
of a control system that includes the use of a PLC and a frequency converter to control
an induction motor. |
