The actual physical quantity, in addition to switching quantity, analog quantity, also has motion control. For example, the displacement of machine tool components is often expressed in digital quantities.
The effective method for motion control is NC, namely digital control technology. This is a computer-based control technology born in the United States in the 1950s. Today, it is very popular and perfect. At present, the CNC rate of metal cutting machine tools in advanced countries has exceeded 40% – 80%, and some even higher.
PLC is also a computer-based technology, and is increasingly perfect. So it can also be used for digital quantity control.
PLC can receive counting pulse, and the frequency can be as high as several k to tens of k Hz. This pulse can be received in many ways, and can also be received in multiple ways. Some PLCs also have pulse output function, and the pulse frequency can also reach tens of k. With these two functions, plus the data processing and computing capabilities of PLC, if equipped with corresponding sensors (such as rotary encoders) or pulse servo devices (such as annular distributors, power amplifiers, stepper motors), 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.
With the development of PLC technology, its data storage area is becoming larger and larger. For example, the data storage area (DM area) of DEVISON PLC can reach 9999 words. Such a huge data storage area can store a large amount of data.
Data acquisition can use a counter to record the number of collected pulses and transfer them to the DM area regularly.
A/D unit can also be used for data acquisition. When the analog quantity is converted into digital quantity, it will be periodically transferred to the DM area.
The PLC can also be configured with a small printer to print the data in the DM area regularly.
The PLC can also communicate with the computer. The data in the DM area is read out by the computer and then processed by the computer. At this time, PLC becomes the data terminal of the computer.
Power users have used PLC to record their electricity consumption in real time, so as to realize the charging method of different electricity consumption time and different pricing, and encourage users to use more electricity during the low period of electricity consumption, so as to achieve the purpose of reasonable electricity consumption and energy saving.
