The implementation of PLC remote control usually involves two levels, hardware and software, and requires the use of a variety of technologies and equipment to achieve it. The following are its common implementation methods: Hardware level PLC equipment: It is required to have a communication interface, such as Ethernet interface, RS485 interface, etc., to transmit […]

PLC logic control refers to the use of programmable logic controllers (PLCs) to control various logical relationships in industrial production processes or equipment. The following is a detailed explanation of its meaning, working principle, application, etc.: Basic meaning PLC logic control is mainly based on logical operations to process input signals and generate output signals

The production of PLC control cabinets involves standards in many aspects, including design, electrical component selection, cabinet manufacturing, wiring, etc. The following are some of the main production standards: Design standards Functional design According to the actual control needs, the electrical schematic diagram should be accurately drawn to ensure that the connection and signal transmission

The frequency conversion control cabinet plays an important role in the automation system in many aspects, which is mainly reflected in the following aspects: Motor control and protection Speed ​​control: By changing the power supply frequency to adjust the speed of the motor, the motor can run at a suitable speed under different working conditions

Hardware failure Sensor failure Abnormal signal: The temperature sensor may have a large deviation in the measured value. For example, due to aging or damage of the sensor probe, the measured temperature is much higher or lower than the actual temperature. The pressure sensor may output an erroneous pressure signal, which may be due to

In industries such as chemical and pharmaceutical, reactors are key equipment, and their performance and efficiency directly affect the quality and output of products. However, traditional reactor control methods often have problems such as human operation errors and unstable equipment operation. In order to solve these challenges, it is particularly important to choose a PLC

Correctly understanding and using the rated values ​​and limits of the PLC control cabinet is essential to ensure the stable operation of the industrial automation system. Here are some methods and suggestions: Rated voltage Confirm that the voltage of the input power supply is consistent with the rated voltage of the PLC control cabinet. Before

In the field of industrial automation, PLC (Programmable Logic Controller) control cabinets play a vital role. Understanding their ratings and limits is essential to ensure safe and stable operation of the system. Rated voltage PLC control cabinets usually have a specific rated voltage, which is the power supply voltage required for the normal operation of

If the PLC control cabinet is poorly grounded, the following series of adverse effects will occur: Increased electromagnetic interference: Poor grounding will make the PLC control cabinet more susceptible to external electromagnetic interference. For example, the electromagnetic field generated by nearby high-voltage transmission lines, high-power motors, inverters and other equipment may couple into the PLC
