What is a Motion Controller A motion controller is a specialized controller that manages the operation of electric motors. For example, it controls the motor to move an object upwards to a designated position using a limit switch to activate an AC contactor, then downwards again, or it can use a timer relay to control … Read more
Focusing on Automation Training for 14 YearsTechnical Training Network“ The programming soft components of the PLC are essentially memory units, each with a unique address. To facilitate different programming functions, the memory units are partitioned, resulting in various types of programming components. Soft components are devices within the PLC that have certain functions, composed of … Read more

To learn PLCs, one must deeply understand the scanning process and execution principles of PLCs to write programs reliably and accurately. In simple terms, PLC programs are scanned and executed in a sequential loop from top to bottom and left to right, which requires three processes to truly output and implement external actions. Step One, … Read more
1. Concept of Interrupts and Interrupt Events In our daily work, we follow a normal workflow. If an emergency occurs or we need to attend to another task after a certain period, we must first stop our current work to handle the emergency or the other task. This stopping of work is called an interrupt, … Read more
First, let’s understand what digital and analog signals are?Why do PLCs need to use analog signals? Digital Signals Digital signals are a type of physical quantity. Their changes are discontinuous over time, occurring only at a series of discrete moments. This type of physical quantity is called a digital signal. It refers to quantities that … Read more
