In factories, different devices are designed by manufacturers, and there are many types of PLC control systems. The types of sensors used also vary; some use NPN type, while others use PNP type. Therefore, many electricians feel confused when they see NPN and PNP sensors and do not know where to start. Here, I will … Read more
Hello everyone! Today, we will discuss the basic knowledge of input and output modules in PLC programming, especially wiring and configuration. This is the most critical step in learning PLCs because only with correct wiring and configuration can the PLC “understand” your commands and reliably control field devices. Even if your program is perfect, if … Read more
It is common to encounter situations in industrial settings where devices have dozens of sensors and actuators, each requiring individual wiring to the PLC. This not only takes a long time to wire but also increases the chances of errors, making troubleshooting particularly challenging later on. Today, let’s discuss AS-Interface bus technology, a fieldbus solution … Read more
Connection Method 1: Not recommended, interference leads to continuous bugs. Solution 2: Connect the passive termination resistor as shown in the figure: recommended. Connection Method 3: Connect 5V active termination resistor: Incorrect Connection Method: Error 1: The bus must be connected in a linear fashion, not in a star configuration. Error 2: Missing termination resistors. … Read more
Search on WeChat Technical Training The PLC and the inverter have a relationship of inclusion and being included. Both can execute specific commands to control electric motors. The PLC is a hardware device for program input execution, while the inverter is one of them. However, the scope of the PLC is broader than that of … Read more
The relationship between PLC and inverter is one of inclusion, where both can execute specific commands to control electric motors. The PLC is a programmable hardware for executing programs, while the inverter is one of the devices it can control. However, the PLC’s scope is broader than that of the inverter, enabling it to control … Read more
Distinguishing between neutral and ground wires: The ground wire is required to be yellow/green striped during installation, so it can be identified by its color. The neutral wire is generally blue. 1. Set the multimeter range switch to the AC voltage setting, which should be available on all multimeters. 2. The range should be from … Read more
