PLCs have evolved astronomically since those early years. From graphical interface to wireless connectivity to machine learning, today’s PLCs are light years beyond that of their ancestors. Customers can now tailor fit PLCs to meet the needs of their applications.
Gantry cranes are mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. To manufacture large ships, giant gantry cranes are essential. In addition, the loading and unloading of containers in ports requires the participation of gantry cranes. To make the gantry crane work efficiently, PLC is essential. It can realize the...
To make the cold roll forming machine work efficiently, high-performance programmable logic controllers and high-precision servo motors are indispensable.
We are a country rich in coal and low in oil. Coal has always been in an absolute leading position in the composition of energy utilization. Even after many years of energy conservation and emission reduction work, the utilization of coal is still an astronomical figure. Except for a small part that is used for heating in winter, most of the coal has become "food for ind...
Closed-loop servo is actually a servo motor, because it has an encoder structure that can feed back the motion state of the motor to form a closed-loop control. Compared with other open-loop control motors, the displacement accuracy of the servo motor is relatively high. When a pulse is given, it will move a position. After the power is turned off, the motor rotor will n...
The scientific name of PLC is programmable logic controller, which is an essential machine for realizing industrial automation production. Next, let’s talk about what environmental factors should be considered in the use of PLC: First of all, it is temperature. Each PLC has its own most suitable working temperature range. It is not acceptable to exceed the lower limit o...
For example, we now have two PLCs, one has only one CAN port, the other has a CAN port and an Ethernet port, and the devices to be controlled by the PLC are all network ports. Well, the first PLC can indeed control those production equipment through the CANopen bus, but no one knows how it is controlled. why? There is no visualized data for monitoring! If you want visual...
What we are going to talk about today is not to add monitoring to the car or install a monitoring software APP to the mobile phone, but to view the motion data of the car through the mobile phone. We know that there are several buses in a car to connect various devices, such as CAN bus, LIN bus, MOST bus and so on. The above types of buses have different characteristics,...
When we choose PLC as the controller for the construction of industrial automation production line, we have to go through steps including clarify demand, formulate solutions, determine models, programming and satisfy needs.
This article introduces the concept of PLC from five basic angles in a simple and simple way, and at the same time gives a detailed and appropriate explanation for each item. Starting from PLC interface and its functions and then talk about the basic units. The main body is about the technical parameters and makes comparison between PLC control system and relay control s...
