At the end of this course, it can control large systems, long and detail It will minimize the risk of making mistakes by dividing the PLC programs requiring into small sections, You will be able to write the program of the entire system in a derzer. Therefore, the entire system You will be able to divide into small processing courses. A few advantages of writing programs in this way has. One of the biggest advantages is that the error is not in the whole system when an error occurs in the system, It is possible to search in the error section. Therefore, the replacement of the faulty section quickly will determine, the necessary changes in a short time you will provide. In addition, in the programs written with SFC method, the system later Adding a lesson or adapting to the system against subsequent changes will be possible. Since the system is the development of the system, the transactions that can be done later You will be able to transfer it to your system easily. You have learned in previous lessons It is also aimed to reinforce the information with this course. SFC, Sequental Function Chart (sequential function graph) It is the shape and the situation also means transition graph. To be changed or developed It is a programming method that shows step transactions. With SFC programming method, From time to time repeated steps are performed with PC commands in the diagram. With the SFC system, when designed sequential control or logic control circuits, Without the use of traditional and complex design methods, very easily Programming is done. Since this system can be made easy programming, IEC standard remarkable for. If we look at all these positive aspects, the SFC system is rapidly seems to develop. Defining the problem in order to adapt PLC to the system successfully, such as choosing the necessary peripherals, preparing the required program, making the necessary connections We need to have skills. Even one of these skills is missing, the unit Prevents the control of the correct control.
