When it comes to the work of electricians, the older generation relied on abacuses and notebooks. To calculate loads, they would simply draw a line with a pen; to change wiring, they would manually sketch a wiring diagram. Later, relays were strung together like beads on an abacus, where any movement would trigger a response, … Read more
1. What Exactly Is PLC? Think of It as an “Industrial Butler” PLC (Programmable Logic Controller) is like the “smart butler” of a factory, responsible for receiving sensor signals (such as high temperature or machine jams) and controlling equipment actions based on pre-set programs (like shutting down machines or activating alarms). For example, the automatic … Read more
Search WeChatTechnical Training The function of PLC automatic sequencing is to control equipment to operate according to a pre-designed process flow. There are several methods for writing PLC automatic programs, and below we will provide a detailed explanation. PART 01First Method: Set and Reset Auxiliary Relays This method is the most primitive and basic way … Read more

01 Car Bidirectional Movement Implement the bidirectional movement of the car using S7-200’s automatic control. The control process is to press the start button, the car moves from left to right (and then back from right to left). When it reaches the right (or left), it hits the limit switch on that side, and the … Read more
01 Car Bidirectional Movement Use S7-200 to achieve automatic control of the car’s bidirectional movement. The control process is as follows: when the start button is pressed, the car moves from left to right (and vice versa). When it reaches the right (or left) limit switch, the car automatically returns. It continues this back-and-forth movement … Read more
