The main role and function of TP touch screen

When the touch screen is connected with the PLC, in fact, the memory of the PLC is used, (the contact screen also has a small amount of memory, which is only used to store system data, that is, the screen, controls, etc.), the touch screen and the PLC communication is generally a master/slave relationship, that is, the touch screen reads data from the PLC, and after making a judgment, it is displayed in the display ...

(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 ...

Inverters are mainly divided into two categories according to the frequency conversion method: communication/DC/communication and communication/communication inverters. AC/DC/AC inverter, also known as direct inverter, refers to the operation, the first 50Hz power frequency communication power is converted into pulsating direct current through the rectifier module unit, ...

1.XG1 series is the latest modular medium-sized PLC of Xinjie, aiming at the domestic high-end market. peculiarity Medium-sized series PLCs with powerful functions and larger storage capacity Support 4 channels of 200K high-speed pulse transmission ...

Confirm the rated power and resistance value of the braking resistor. The rated power of the braking resistor should be determined according to the power and moment of inertia of the motor, and the resistance value should be selected according to the specifications of the VFD. In the VFD's parameter settings, find the parameters related to the braking resistor, such as the braking resistor selection ...

1. The speed regulation power is high, which is an efficient speed regulation method. This is because after the frequency change, the motor is still working in close proximity to the synchronous speed, and the rated slip is fundamentally adhered to. It's just that in the frequency conversion equipment system, there will be conversion loss, and because of the influence of higher harmonics, the loss of the motor will increase.

Of course, PLC control is much more reliable than relay control, but if the device does not meet the requirements, it will not work. Therefore, the PLC machine should be installed correctly outside. (1) Pay attention to the environment of the installation The temperature should not be lower than 0°C and above 55°C, for example, not installed by a large stove, and ...

Introduction to the glass sealing industry As a relatively old industry, the vitality of the glass industry has further burst out in the modern society, due to the social development and the improvement of people's aesthetics, the demand for glass in all walks of life is also increasing, which is also more abundant.

The internal disturbance of the PLC system is mainly caused by the mutual electromagnetic radiation between the components and circuits inside the system, such as the mutual radiation of logic circuits and their influence on the imitation circuit, the interaction between the imitation ground and the logical ground and the mutual mismatch between components. How to deal with PLC long distances effectively ...

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. ...

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 ...

1. Introduction TP Contact Industrial Graphic Displayer (referred to as contact screen) is a human-machine interface (known as HMI or MMI in foreign countries) that connects humans and machines (mainly PLC), which is known as the face of PLC. It is a generation ...

World electrical safety standards: The requirements are in line with the world's electrical safety standards, such as the CE standard in Europe and the UL standard in the United States. These specifications specify the requirements for electrical safety functions, mechanical safety functions, EMC functions, etc. Machine...

The voltage waveform output by the inverter is similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components, especially the higher harmonics will increase the output current of the inverter, form the motor winding heating, produce vibration and noise, accelerate the aging of insulation, and even ...

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...

When we select the right inverter brand, we need to recognize whether it can help enterprises better manage the risks and costs caused by potential safety, security and downtime accidents. Safety: Reverse arc drives assist users in meeting stringent reverse arc specifications. These inverters (Variabl ...

1、CPU。 The CPU of the plc is actually the central processing unit, which can carry out the operation and processing of various data, convert various input signals into input registers, and then carry out logical operations, timing, counting, arithmetic operations, data processing and transmission, communication networking and various operations, ...

Xinjie PLC 丨Communication failure is generally summarized as the following problems: (1) Communication parameters: The communication parameters of Xinjie PLC communication port and peripheral equipment may be inconsistent. (2) Communication line: The connection may be incorrect, or the contact is poor, the user can replace the communication line and try again.
