Σύνοψη

Writing this report an effort was made to represent the programmable logic controller. In the pages of this project we are trying to examine the PLC from all the possible angles. Of course the definition of something is not enough to make us familiar with it. A more careful one pedantic observation will lead us to distinguish its main functioning parts, one by One, After this taking each module we analyzed it and explain its rule in the whole controller's operation.
It should be meaningless to examine a programmable device without referring to its programming facilities. A brief reference has been made in the methods of programming the controller as well as the available programming devices.
In this way the basic idea of the PLC has been given to the Reader, who is waiting for something more practical now. This inquiry will become reality when an application program was asked to be constructed. The application concerns a pallet machine. All the working steps followed till we reached the goal are clearly shown, from the customers' request to the completed construction of the whole switchboard including the PLC and the Ladder Diagram Programming.
The costing for such an application and a comparison with the other correctional methods is presented in chapter three.
At the end of this report, now that we are sure that the reader is more than familiar with the programmable controller a last effort to show the huge capabilities of the PLC. Is made more specifically a number of clever and very useful, small applications programs are shown which can be used inside other user programs to achieve certain goals such as sequentoal switching etc.
Furthermore, a fault Table for the controller's disturbances, the possible reasons that caused them and first actions made by the user.
