PLC carries out analog quantity control, as well as A/D, D/A combined units, which can be controlled by PID or fuzzy control algorithm to achieve high control quality. The advantage of analog control with PLC is that the switching value can also be controlled while analog control is carried out. This advantage is not possessed by other controllers, or the realization of control is not as convenient as PLC. Of course, if the system is purely analog, the performance price ratio of PLC may be inferior to that of regulator.
3. For motion control
The actual physical quantity includes switch quantity, analog quantity and motion control. For example, the displacement of machine tool components is often expressed in digital quantities. The effective method of motion control is NC, that is, digital control technology. This is a computer-based control technology that was born in the United States in the 1950s. Nowadays, it is very popular and perfect. At present, the numerical control ratio of metal cutting machine tools in advanced countries has exceeded 40%~80%, and some even higher. PLC is also a computer based technology, which is increasingly improved. The PLC can receive the counting pulse, the frequency can be as high as several k to tens of kHz, which can be received in a variety of ways, as well as multiple channels. Some PLCs also have the pulse output function, and the pulse frequency can reach dozens of k. With these two functions, plus the PLC”s data processing and computing capabilities, if equipped with corresponding sensors (such as rotary encoders) or pulse servo devices, various controls can be completely realized according to the principle of NC. High and medium level PLC, also developed with NC unit or motion unit, can realize point control. The motion unit can also realize curve interpolation and control curve motion. Therefore, if the PLC is configured with such a unit, the NC method can be used to control the digital quantity. The newly developed motion unit even released the programming language of NC technology, which provides convenience for better digital control with PLC.
4. Used for data collection
With the development of PLC technology, its data storage area is becoming larger and larger. For example, the data storage area (DM area) of the PLC of DEVSON can reach 9999 words. Such a huge data storage area can store a large amount of data. The counter can be used for data acquisition to accumulate and record the number of pulses collected and periodically transfer them to the DM area. A/D unit can also be used for data acquisition. When analog quantity is converted into digital quantity, it will be periodically transferred to DM area. The PLC can also be configured with a small printer to print the data in DM area regularly.
The PLC can also communicate with the computer. The computer reads the data in DM area and the computer processes the data again. At this time, PLC becomes the data terminal of the computer.
Power users used to use PLC to record their power consumption in real time, so as to realize different charging methods for different power consumption times and pricing, and encourage users to use more power when power consumption is low, so as to achieve the purpose of reasonable power consumption and energy conservation.
5. For signal monitoring
There are many self checking signals and internal devices of PLC, and most users do not fully play their roles. In fact, it can be used to monitor the work of PLC itself or the control objects. For a complex control system, especially an automatic control system, it is very necessary to monitor and even further self diagnose. It can reduce system failures, make it easy to find faults, increase the cumulative mean time between failures, reduce the time to repair faults, and improve the reliability of the system.
6. Used for networking and communication
PLC has strong networking and communication capabilities, and new networking structures are constantly introduced.
The PLC can be connected with the personal computer for communication, and the computer can be used to participate in the programming and control management of the PLC, making the PLC more convenient to use.
In order to give full play to the role of computers, one computer can control and manage multiple PLCs, up to 32 of them. One PLC can also communicate with two or more computers to exchange information, so as to realize multiple monitoring of PLC control system. PLC and PLC can also communicate, one to one PLC can communicate, and several PLC can communicate, up to dozens or hundreds.
PLC and intelligent instrument, intelligent execution device (such as frequency converter) can also be networked for communication, data exchange and mutual operation. It can be connected into a remote control system, and the scope of the system can be as large as 10km or more. It can form a local network. Not only PLC, but also high-end computers and various intelligent devices can enter the network. Bus network or ring network can be used. The net can also be set. The network can also be bridged. Networking can organize thousands of PLCs, computers and intelligent devices in a network. The nodes between networks can communicate and exchange information directly or indirectly.
Networking and communication are meeting the needs of today”s computer integrated manufacturing system (CIMS) and the development of intelligent chemical plants. It can make industrial control from point to line and then to aero, so that equipment level control, production line control and plant management control can be integrated into a whole, thus creating higher benefits. This infinitely beautiful prospect has been more and more clearly displayed in front of our generation.
The above applications are mainly qualitative. In terms of quantity, there are large and small PLCs. Therefore, its control range can be large or small. Small ones only control one device, or even one component, or one site; Large can control multiple equipment, one production line and even the whole factory. It can be said that industrial control of large and small occasions can not be separated from PLC.
