In my diploma, I described the project of automation of vertical rollers, which are integrated in a larger production line for light construction panels in company Trimo. In the project, I used the existing PLC controller SIEMENS CPU318-2. Position measuring is carried out by MTS Temposonics measuring rods. The end positions are sensed by inductive switches. Movement of the vertical rollers is achieved by SEW drive system, which consists of a frequency inverter, induction motor and a gearbox.
Firstly, I wrote a program (in the programming environment SIMATIC Manager) for the PLC, which was used to test the functioning of the measuring rod.
Then I made a plan of all electrical connections. With the help of this plan we installed all the necessary elements in the production line. For proper functioning, some modifications of my program were done.
Now the position of vertical rollers is controlled through the SCADA interface, which is also a part of the existing control system on this line.
