The role of article, understand PLC -

PLC ( Programmable controller) Is actually a kind of ability to work stable in a complex environment of industrial computer, through internal central processing unit can it handle switch from external signals, digital signals and analog signals, etc. , is a 'powerful'. Let's talk about the role of the industrial control device of PLC! ! ! !

to say the role of the PLC have to say it in the field of industrial control. As is known to all, at the beginning of the birth of PLC controller is applied to industrial production line, after nearly 50 years of development, the role of PLC in industrial control field is becoming more and more important. Simple logic control about us from the industry, who go through modernization of PLC relay control circuit are not used; So in the modern industrial integration control system of PLC is also one of the core of the main control device, such as in flexible manufacturing system ( FMS) PLC ACTS as will receive various peripherals in the signal conversion, calculation and output and control the effect of various load; With modern PLC technology is more and more perfect, a lot of brands of PLC are reserved various communication interfaces, to PLC and PLC, PLC and peripherals ( Such as frequency inverter, touch screen, etc. ) Long-distance communication between them, in order to realize the remote control provides a possible; In the modern intelligent manufacturing, industrial robots working on the production line, industrial robots have to get all kinds of information through PLC for processing and supply of industrial robots. Thus, PLC in simple logic control and PLC in modern industrial intelligent integration system function is unchallenged!

PLC controller not only has a great role in industrial field, are also common in other areas, such as various kinds of high-rise buildings in the elevator control circuit; Directing traffic used in traffic lights control circuit; Life to see music fountain control circuit, the control of advertising lights, and so on are visible to the application of PLC.

PLC is executed only a single application of industrial computer.

main function is through the change of peripheral modules new equipment. Functionality transformation by means of module combination, to achieve rapid development and formation productivity, reducing development time and risk of all kinds of tests.

in the last century in 1968, the first appeared in 69. Engineers in the era of industrial development, on the one hand, language is not, and also need someone can change rapidly in field equipment function and the running maintenance. Can't all by engineers with a burning device to the scene to direct processing, it also does not have a laptop, only will return to factory processing equipment, so need a can let the workers operating industrial computer. When burning program needs to ultraviolet light Eprom for several hours.

modern PLC has already been upgraded to a very strong degree, requirements for the operator has also improved, but the scene changes, is advantageous for the mechanic or dominant mode.

so PLC main function is fast, convenient operation, easy to maintain.

the function of PLC for example is to give each production equipment and a brain, and how the brain works? And what are the advantages? Its development prospects? That we have to answer one by one.

to equipment and 'brain'

the traditional manufacturing equipment, mostly by a series of relay and array logic circuit composed of input and output control equipment. The introduction of PLC, make production equipment to increase the CPU ( The central processing unit) , memory, input/output and programmable controller. Therefore, the introduction of PLC, lays a foundation for intelligent manufacturing.

when solve the production equipment of the 'brain', is about to start to use the brain.

1。 To provide production equipment parameters. By the design department and technology department offers a variety of requirements under the condition of parameter requirements, through the PLC equipment receiving, execute instructions for the machines.

2。 Grab the running result of the manufacturing facilities and state. Collect production equipment operation parameters and the final result of feedback to the development and design department, production management, production equipment working conditions, through the analysis of the large data real-time decide when to need maintenance, when need to increase the solution concentration, when need to adjust the temperature and humidity, etc.

when solved these two aspects, we will implement the preliminary intelligent manufacturing. We often hear is called industrial 4. 0. With ever increasing future labor costs, intelligent manufacture most instead of manual operation, to achieve quality and efficiency of double ascend, therefore, in the back for a long period of time, artificial intelligence development prospect.

the realization of artificial intelligence, it is very important is programming, including PLC programming is also needed. Want to learn programming, there is a language is the fundamental course of all programming languages, like mathematics is the foundation of all science and engineering discipline. Only learned the language is the C language, C language, and then to learn other languages, an introduction to very well, here I also recommend you a practical C language tutorial, I hope you can learn it also, for further ascension space.
