140XCP51000 Data Communication Networks

140XCP51000 makes the microprocessor and other ic and other related components of the price is getting cheaper and cheaper, but the function is more and more enhanced, in addition to the 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 is not only can 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 the entire system of graphical monitoring. Graphical monitoring, so in addition to the control of a single machine, it is easier to achieve the goal of factory automation, so plc is now widely used in factory automation (fa) and flexible manufacturing system (fms), the application areas covered by the automotive industry, machinery, iron and steel industry, metallurgy, textile, petroleum, chemical, food manufacturing, automatic warehousing, troubleshooting and system monitoring and other trades and industries, can be called the It can be regarded as the sharp tool of electromechanical integration and the pioneer of industrial automation.

The 140XCP51000 utilizes an intuitive approach, meaning it is based on the circuit designer’s own learning experience, which 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.
