In this study also some developed automation examples designed by students were introduced This platform can be. used for Electrical and Electronics students and it will be useful for education of automation systems understanding. PLC and SCADA systems and improving talents of students about designing new automation systems. 2 Developed Experimental PLC Training Set, PLC devices are well adapted to a range of automation tasks These are typically industrial processes in. manufacturing where the cost of developing and maintaining the automation system is high relative to the total cost. of the automation and where changes to the system would be expected during its operational life PLC devices. contain input and output devices compatible with industrial pilot devices and controls and little electrical design is. required PLC applications are typically highly customized systems so the cost of a packaged PLC is low compared. to the cost of a specific custom built controller design On the other hand in the case of mass produced goods. customized control systems are economic due to the lower cost of the components which can be optimally chosen. instead of a generic solution and where the non recurring engineering charges are spread over thousands or millions. Developed education set is shown in Figure 1 consists ofaS7 200 CPU 224 PLC a power supply an RTD module. and an EM 235 analog module PLC inputs and two bi directional switches were connected to start and stop buttons. Two way switches with input were given directly to the PLC so the PLC program can be tested on the computer At. the same time these switches are input elements and they provide the opportunity for connecting to the system. without using any sensor and developed system can be tested in real time Outputs of the PLC and normally open. normally closed and com terminals of the relays are suitable for connection of any loads or contactors In this way. various loads can be connected to the system easily Relays are mounted with the LED outputs so relay outputs can. be seen through the training set, Developed education set also has an EM 231analog module some assured physical quantities by the sensors just. like temperature pressure etc are taken as analog currents and voltages so this allows to transfer the physical data. to CPU for determining Students can test and compile their developed PLC programs with the Micro winStep 7. PLC program so they have the chance for testing their applications also have the opportunity to make. applications with this education set and they can learn about the subjects of PLC PC communication program. compilation PLC connections testing and even using the actual input output components. 952 Gokay Bayrak and Mehmet Cebeci Procedia Social and Behavioral Sciences 47 2012 950 955. Figure 1 Developed experimental PLC training set, Analog module of the system has four analog inputs EM231 and its analog inputs are shown in Figure. 1 Developed PLC set also allows selecting sensor inputs or manual switching inputs thanks to used 0 1 2 switches. Thanks to these switches sensor inputs can be transfer to PLC inputs in real time by using. Also PLC programmes can be tested by using manually to 2 In developed system training set is. programme Education set also has an RTD module for using temperature sensors just like PT 100 so it is also an. advantage for creating new automation projects,3 Developed Experimental SCADA Training Set.
Supervisory Control and Data Acquisition refers to the centralized systems which control and monitor the entire. sites or they are the complexes of the systems which are spread out over large areas just like between an industrial. plant and country Mostly all the control actions are automatically performed by the remote terminal units RTUs or. by the programmable logic controllers, In this study as a part of developed automation platform in addition to PLC education set also an SCADA. education set was developed and it was communicated with PLC and a PC A touch panel as an HMI unit was used. for this purpose and thanks to used SCADA software it can be programmable by PC Developed education set is. shown in Figure 2 Automation platform consists of developed PLC and SCADA education sets and a PC has. development software These parts of automation platform communicate with each other and it is possible to. develop and test automation projects, Figure 2 Developed experimental automation education system.
