5X00062G01 5X00063G01 makes the microprocessor and other ic and other related components cheaper and cheaper, but the function is more and more enhanced, in addition to addition, subtraction, multiplication, division and other arithmetic algorithms, comparisons, and data processing functions and other convenient application of the instructions, coupled with the composition of the data communication network, so that the plc can not only be operated on-line with the PC, and in addition to the provision of the human-computer interface, but also for the work program or graphical monitoring of the entire system, so in addition to the control of a single machine, it is easier to achieve the goal of factory automation. Work program or the entire system of graphical monitoring, so in addition to the control of a single machine, it is easier to achieve the goal of automation of the entire plant, so plc is now widely used in factory automation (fa) and flexible manufacturing systems (fms), the application areas covered by the automotive industry, machinery, iron and steel industry, metallurgy, textiles, petroleum, chemical industry, food manufacturing, automated warehousing, diagnostic and system monitoring, etc., which is known as the most advanced and reliable system in various industries. It is a powerful tool for electromechanical integration and a pioneer of industrial automation in various industries.

5X00062G01 5X00063G01 adopts the intuitive method, that is to say, it is based on the circuit designer’s own learning experience, and is more subjective and direct. Must go through a period of blind man feeling the elephant try and error (try and error) period, the program to eliminate the error in order to meet the required function or action requirements; therefore, the design of the program varies from person to person, in addition to the original program designer, the user or the maintenance personnel is not easy to understand its action process, that is, the program readability is low.

5X00062G01 5X00063G01 converts the control circuit in the electrician’s drawing directly into the corresponding ladder diagram. Because the plc ladder diagram stipulates that the contact is in the front and the output coil must be at the end of the circuit. Therefore, first of all, we have to redraw the electrical diagram and change the position of the contact and output coil in the diagram to meet the requirements of the plc ladder diagram, but there are actually some veins to follow in the program design, only that the books in the workshop seldom mention this part. The extensive use of automation technology in the admission of coal mining and sampling equipment, greatly liberating workers from tedious physical labor and unsafe working environment, significantly improving the working environment and increasing the efficiency of workers.
