With the continuous development of computer control technology, the application of editable logic controllers is also becoming increasingly popular, becoming an important component of automation technology. Among them, Siemens S7 series PLCs also account for a large proportion in industrial control in China. As an intuitive and convenient way of human-computer interaction, touch screens have been widely used in industrial control. In the long-term use process, the author found that many people are unfamiliar with data communication between different models of PLCs, as well as between Siemens PLCs and third-party touch screens. This article will use specific examples to illustrate how to use Ethernet to achieve communication between MCGS touch screens and Siemens S7 series PLCs, laying the foundation for industrial automation control systems. 1 Hardware compos...

Accept the fully connected MAC solenoid valve structure and perform element leakage sealing throughout the entire pressure range, making it easier for the pipeline  system to perform ball cleaning and pipeline maintenance. Accept special molding process, lining the lining material on the inner wall of the valve housing, which can  withstand the erosion of strong acid and alkali media. The valve structure consists of a full bore floating ball type (two-stage) and a full bore fixed ball type  (three-stage), which are important for cutting off or connecting corrosive media in pipelines, and can be used for fluid adjustment and control.     The characteristic of MAC solenoid valve is that the valve seat sealing ring is composed of multiple layers of stainless steel sheets on both sides of a soft T-shaped  sealing ring.   The sealing surface betw...

1. On site inspection   Regular on-site inspections can effectively identify problems and provide timely maintenance. The inspection content includes the working status of the frequency converter and distribution equipment, the flow rate of the cooling system, the condition of the cooler, the temperature, and the ventilation status Control the contact status of signal lines, wiring terminals, etc. If there are any abnormalities, they should be dealt with promptly.   2. Maintain cleanliness   The frequency converter mainly emits heat through air cooling, so the module surface, fan, and ventilation holes must be kept clean. If not cleaned for a long time, it will reduce the heat dissipation effect of the inverter, and in severe cases, it will Overheating can cause accidents and also affect the service life of the frequency converter.   3. Keep the cable in goo...

Battery alarm: ① "Rechargeable battery warning - an aging battery was found, but the battery is not functioning properly   The quantity is still sufficient   ② Unable to cache   Analysis: This situation usually occurs when the robot is first turned on, and the battery plug is not plugged into the CCU board in the control cabinet when the robot leaves the factory.   Measure: Find the battery power plug inside the control cabinet and plug it into the CCU card socket corresponding to the label.   3.  KSS00203- Fully operational and open   Measures: ① U...

Variable Frequency Drive System is a power electronic device system used to control the speed and output frequency of AC motors. It changes the frequency and  voltage of the input power supply   Control the speed and output power of the motor to meet precise control under different load requirements and operating conditions.   The hardware of the frequency converter system mainly includes the following components:   Inverter host: The inverter host is the core equipment responsible for controlling the speed and output frequency of the motor. It typically includes digital signal  processors (DSP) or microprocessors, power electronics, input/output interfaces, etc.   Rectification device: The rectification device converts AC power into DC power and provides power to the inverter host. It usually includes components such as  rectifier...

1、 Voltage measurement method: Measuring voltage is the basic method for repairing industrial touch all-in-one machines and is often used in  practice. It mainly measures the working voltage of circuits and components to identify the faulty parts and components   Make a judgment. Voltage measurement can be divided into two categories: measuring AC voltage and measuring DC voltage.   Measuring AC voltage is to use the AC voltage value of a multimeter to measure the AC voltage value of the industrial touch all-in-one machine  power supply. Of course, a capacitor with a sufficient withstand voltage of around 0.1 μ F can also be connected in series to the multimeter for  measurement   The AC part of the field scanning output circuit, line scanning output circuit, video amplification circuit, and other components. Use a multimeter  ...

Torque sensors, also known as torque sensors, torque sensors, torque meters, are divided into two categories: dynamic and static. Among them, dynamic torque sensors can also be called torque sensors, torque speed sensors, non-contact torque sensors, etc Rotating torque sensors, etc. A torque sensor is a device that detects the perception of torsional torque on various rotating or non rotating mechanical components. The torque sensor converts the physical changes in torque into precise electrical signals. Torque sensors can be applied in the manufacturing of viscometers Electric (pneumatic, hydraulic) torque wrenches have the advantages of high precision, fast frequency response, good reliability, and long service life.   A torque sensor is a precision measuring instrument that measures various torques, rotational speeds, and mechanical power. The application scope is very w...

With the development of intelligent manufacturing and IoT technology, industrial sensors have become the infrastructure for industrial automation and intelligent  manufacturing. Industrial sensors can achieve real-time monitoring and control on the production line by collecting and transmitting various information, which  helps improve production efficiency, reduce costs, and ensure product quality. So how can we better achieve data collection for industrial sensors?   1. Choose the appropriate sensor   Firstly, we need to choose the appropriate sensor. When selecting sensors, factors such as measurement range, accuracy, sensitivity, stability, anti-interference ability,  and usage environment need to be considered. At the same time, in order to reduce costs and complexity, multi-sensor modules with multiple functions should be  selected to integrat...
