PLC networks are composed of several levels of subnetworks, and the communication process between these subnetworks is determined by communication protocols, with the communication method being the core content of the communication protocol. The communication methods include access control methods and data transmission methods. The so-called access control (also known as access control) method refers … Read more
With the continuous expansion of production scale and the development of production technology, there are increasingly higher requirements for the level of automation in the production process. Therefore, industrial instruments have also undergone a development process from non-existence to existence, from simplicity to complexity, and from single-function to multifunction. Initially, instruments could only measure and … Read more
PLC comes in various sizes, allowing for a wide range of control applications. Smaller PLCs may control a single device, a component, or a station, while larger PLCs can manage multiple devices, an entire production line, or even a whole factory. It can be said that PLCs are indispensable in both large and small industrial … Read more
