In projects, the host computer often needs to interface with PLC communication. Today, we will introduce the commonly used S7.NET communication for PLCs. In practical applications, the common control methods are as follows: one PLC controls one device, one PLC controls multiple devices, and multiple PLCs control multiple devices. Similarly, the host computer also needs … Read more
A PLC (Programmable Logic Controller) consists of hardware components such as a CPU (Central Processing Unit), memory, I/O (Input/Output interfaces), power module, and communication module. Among these, the I/O interface is a critical component that connects the controller to external devices, responsible for signal input (Input) and output (Output). Below, we will discuss dry contact … Read more
The Siemens S5 series PLCs commonly found in the industrial market in China include three main models: U-type (general-purpose), W-type (word processing), and R-type (switching). Different models of PLCs exhibit different fault manifestations and diagnostic methods.
