The fundamental characteristics of the three major control systems of PLC, DCS and FCS At present, there are three major control systems in the operation of industrial processes in continuous process production, namely PLC, DCS and FCS. The fundamental characteristics of each of them are as follows: 1PLC (1) From the development of switching control to sequential operation...

In the instruction manual of the inverter, there is a column that discusses in detail the fault code display of the inverter. 　　1. Short-circuit maintenanceIf there is short-circuit maintenance on the side of the inverter's operation, "0" means that the inverter has short-circuit elements inside or outside. There are several reasons for this ...

1. High reliability The PLC adopts a series of anti-interference methods in hardware and software, so that it can be directly installed in the industrial site and operate safely and reliably, anti-magnetic, anti-seismic and dust-proof. 2. Programming is simple and easy to grasp ...

Small PLC manufacturers introduce that PLC products have a wide variety of products, and the specifications and performance are also different. The classification of PLCs is usually based on their structure, function and number of I/O points. 1. Classified by input/output points (1) ...

Assuming that the inverter has a long service life, heat dissipation must be carefully considered. Because the equipment failure rate of the inverter increases exponentially with the increase of temperature, the service life decreases. If the operating temperature rises by 10 degrees, the service life of the inverter will decrease. ...

The development status of human-computer interface shopping malls in China China is the shopping mall with the largest demand for human-computer interface in the world, but it is not the shopping mall with the highest sales of human-computer interface products in the world.

　　1. Four-wire resistive touch screen: It is not afraid of dust, oil and photoelectric disturbance, and is afraid of scratches is its main defect. It is suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.; 2. Five-wire resistor ...

(1) What is the current setting value of the thermal relay? The setting current of the thermal relay refers to its action current, that is to say, it is adjusted between 0.95 - 1.05 times of the rated current of the motor being maintained.

1. Hardware purchase At present, there are a large number of PLC products on the market, more and more cost-effective, and the optional fields are getting bigger and bigger. 1. At the beginning of the scale of the system, it should be determined that the system is a single PLC machine.

1. Check the full-load power supply of the inverter (Variable-frequency Drive (VFD). 1. Ground the terminal strip of the VFD. 2. Type the switching power supply of VFD into the terminal and receive it from the switching power supply through the power switch of the leakage protector. 3. ...

1. When the PLC and the host computer (or touch screen) form a monitoring system, there are many times on the screen that there are "manual", "active" and other control modes (generally more than one). In the program, you can use the "MOV" command. For example, when selecting "manual", the constant 1MOV will be ...

1. Look inside the electrical cabinet, for example, to see if there are small animals and their droppings, and whether there are condensation or water marks. If the dust in the cabinet is large, please clear the external radiator of the inverter. 2. Assuming that the humidity is relatively large, there are condensation or water marks, please open the cabinet door first, ventilate and dehumidify, you can use electric fans, etc.

Why does the motor driven by the inverter overheat? This is due to the fact that the voltage of the inverter drive motor contains a rich high-frequency component. The voltage waveform of the inverter-driven motor is not a sine wave voltage, but a pulse-width modulation (PWM) voltage. According to Fu Liye's analysis, this waveform ...

1. On the premise of satisfying the production equipment and process requirements, the acceleration or deceleration time should be increased as much as possible, and then the overcurrent generation in the process of acceleration or deceleration can be avoided. 2. Check whether the inverter, motor, and production equipment are well matched, whether the transmission part is sensitive, and whether the material is ...

(1) The entire control process works under the Chinese system, and the handling is completely Chinese (2) Realize the active control of batching, blanking, mixing and concrete displacement (3) The mixing time and blanking sequence can be adjusted immediately (4) Batching, blanking, mixing ...

In the process of century industry, the more top-level software and hardware planning for the suspension of frequency conversion skills, first according to the characteristics of traditional air compressor motors, comprehensively analyze the causes of energy consumption and operation characteristics, so as to plan the control of frequency conversion skills speed regulation, air skill tightening, pressure sensing skills improvement, etc.

The most direct cause of cable problems is the breakdown due to the loss of insulation. First of all, there are: a. Overload operation. Long-term overload operation will increase the temperature of the cable, aging the insulation, resulting in breakdown of insulation and degradation of construction quality. b. Electrical: the construction process of the cable head does not meet the requirements.

At present, in the domestic PLC market, there are many kinds, but there are not many domestic PLC manufacturers with real strength, most of the domestic PLC is not an individual without legal person qualifications, or a single-chip microcomputer enthusiast, from the domestic PLC factory to buy the underlying programming code or buy a domestic PLC chip (the domestic P ...

Problem example 1 On the telegram OC problem, measure the 5, 6, and 7 pins of N1 to be 2V. Pin 7 is not 0V for the alarm reason. 1. The "imaginary short" rule of the amplifier is still established, and the N1 chip is good to judge, but the fault is in the bias circuit. 2. Further analysis, at this moment the differential amplifier has ...

Xinjie PLC conditions are established, why is the corresponding coil not in place? There are two possible reasons for this: (1) The same coil may be used in multiple places to perform the double coil output, and when the double coil is output, the coil on the rear side will operate first. （2） ...
