Description
Programmable controller (hereinafter referred to as PLC) from its generation to the present, the realization of wiring logic to storage logic leap; Its function from weak to strong, to achieve the progress of logic control to digital control; Its application field has grown from small to large, realizing simple control of single equipment to competent motion control, process control and distributed control and other tasks. Today's PLC in the processing of analog, digital computing, man-machine interface and network capabilities have been greatly improved, become the mainstream control equipment in the field of industrial control, in all walks of life is playing an increasing role. Application characteristics of PLC 1. High reliability, strong anti-interference ability High reliability is the key performance of electrical control equipment. Due to the use of modern large-scale integrated circuit technology, PLC adopts strict production process manufacturing, the internal circuit adopts advanced anti-interference technology, with high reliability. The use of PLC to form a control system, and the relay contactor system of the same size, electrical wiring and switch contacts have been reduced to hundreds or even thousands of one, the fault is greatly reduced. In addition, the PLC has a hardware fault self-detection function, which can issue alarm information in time when there is a failure. In the application software, the user can also program the fault self-diagnosis program of peripheral devices, so that the circuit and equipment other than PLC in the system can also obtain fault self-diagnosis protection. In this way, the whole system will be extremely reliable.
2. Complete set, perfect function, strong applicability
PLC development to today, has formed a variety of scale of serialized products, can be used in various scales of industrial control occasions. In addition to logic processing functions, PLC mostly has perfect data computing capabilities and can be used in various digital control fields. A large number of various functional units have emerged, so that PLC has penetrated into various industrial controls such as position control, temperature control, CNC. With the enhancement of PLC communication capability and the development of human-machine interface technology, it is very easy to use PLC to form various control systems.
3. Easy to learn and easy to use, welcomed by engineering and technical personnel
PLC is an industrial control equipment for industrial and mining enterprises. Its interface is easy and the programming language is easy to be accepted by engineers and technicians. The graphic symbol of ladder diagram language is quite close to the expression mode and relay circuit diagram, which opens the convenient door for people who are not familiar with electronic circuits, do not understand computer principles and assembly language to engage in industrial control.
4. The design of the system has the advantages of small workload, convenient maintenance and easy transformation
The company focuses on DCS, PLC, robot, large servo four systems
