Process 1: 1. The customer confirms the model of the product to be purchased

Process 2: 2. We will query the price and delivery date according to the model of the inquiry sheet and draw up a detailed formal quotation

FOXBORO P0400VE

Process 3: 3. The customer orders the product after receiving the quotation and confirming that the model is correct

Process 4: 4. The person in charge of the quotation draws up a sales contract according to the model and quantity provided by the customer

Process 5: 5. After receiving the agreement of contract review, the customer will stamp and return it and remit it to the company’s account bank according to the contract sales amount

Process 6: 6. After the financial department of our company finds the payment, the salesperson arranges the delivery and notifies the customer to track the waybill

With A/D and D/A units, the remaining processing is digital, which is not difficult for PLC with information processing capability. Medium and large PLCs have stronger processing power. They can not only add, subtract, multiply and divide numbers, but also square root, interpolate, and perform floating-point operations. Some also have PID instructions, which can perform proportional, differential and integral operations on the deviation control, and then generate corresponding output. It can do almost everything that the computer can do.

In this way, it is completely possible to realize analog control with PLC. The unit value of control can be as small as 1/212 of the measurement range value, most of which are also sufficient.

PLC carries out analog control, and there are units combined with A/D and D/A, and PID or fuzzy control algorithm can be used to achieve control, which can achieve high control quality.

The advantage of using PLC to control analog quantity is that the switch quantity can be controlled while the analog quantity is controlled. 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 use of PLC may not be as good as the use of regulator in terms of performance-price ratio. This should also be seen.

For motion control

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.
