1. Status Control of Workstation 1 When the conveyor belt (Y0) is running, and the defective product detection (M10) is triggered, “Workstation 1 (M1)” is “activated” (set); if the defective product detection is in another state (normally closed logic of M10), then “Workstation 1 (M1)” will be “deactivated” (reset). 2. Timing Logic of the Conveyor … Read more
The Design Requirements for a Perfect PLC Program A complete PLC program is not just about making the system operational; it also requires comprehensive comments, excellent architecture, good scalability, a complete alarm protection system, and a simulation system before operation. 1. Simplicity Keep the PLC program as simple as possible. Simplicity means using standardized program … Read more
1. Effect demonstration, as shown in the video below:2. Function implementation:2.1 Place a multi-state indicator component, with the following general property settings: number of states set to 3, PLC address set to 4x 4300.2.2 Place a bit state toggle switch on the left side of the multi-state display component, as shown in the figure below: … Read more
When first learning PLC programming, many people wonder: in what form do the values we set, such as “Temperature 25℃”, “Pressure 0.4MPa”, and “Motor Speed 1500r/min”, exist in the PLC’s CPU? Why do we need to distinguish between “byte”, “word”, and “double word” when writing programs? Today, we will start from the most fundamental binary … Read more
Q What is thought? It is the result or the system of viewpoints and concepts formed by the reflection of objective existence in human consciousness through cognitive activities. There are good and bad thoughts; correct thoughts can quickly achieve goals. PLC Programming Design Methods In short: Program = Data + Algorithm A good program structure … Read more
Why Choose ST for Writing FB? Clear Logic and Easy Maintenance The ST language expresses logic in text form, making it suitable for describing complex control processes. With a reasonable code structure and comments, developers can easily understand and maintain the code. Modular Programming FB itself is a modular programming unit, and ST allows developers … Read more
In PLC programming, the physical contact of the stop button is generally connected as normally closed, while in the program, it is written as normally open. This type of stop button only serves as a signal in this equipment.Why is the emergency stop in PLC programming opposite to that of a regular emergency stop button? … Read more
Reading time required 5minutes Quick read takes only 2 minutes Introduction As a PLC (Programmable Logic Controller) engineer, we face numerous complex control systems and engineering problems every day. Some of these issues may arise from equipment failures, while others may be due to process inefficiencies or improper program design. Regardless of the situation, we … Read more
In automation control, analog signals are ubiquitous. Whether it is temperature, pressure, flow, or even position signals, they can be converted into voltage or current analog signals. As a type of continuously variable input signal, accurately measuring and converting analog signals is the foundation of an excellent control system. Mastering a reliable method for analog … Read more
