For those just starting with PLCs, mastering the programming language and understanding instructions is one of the fundamental conditions. Regardless of how different your programming habits are from others, you must learn this element of instructions, as programming cannot do without its components. Below, let’s take a look at the extent of the application of … Read more
The national standard of China (GB7665-2005) defines a sensor as: “a device or apparatus that can sense the measured quantity and convert it into a usable output signal according to certain rules.” Sensors, as an important means of information acquisition, along with communication technology and computer technology, constitute the three pillars of information technology. Below, … Read more
In RS485 communication systems, the choice of grounding method is crucial, directly affecting the system’s stability and anti-interference capability. Therefore, engineers need to choose the grounding method reasonably based on project requirements. Below we will discuss which grounding is suitable for the RS485 bus. 1. Single Point Reliable Grounding There can only be one grounding … Read more
In many tech products, heat sinks may be overlooked as less important accessories. However, in NVIDIA Jetson embedded products, the importance of heat sinks cannot be ignored. This article will discuss a heat sink failure case we experienced. A year ago, a middleman who purchased a batch of NVIDIA Jetson Xavier NX module heat sinks … Read more

Programming Language – History FORTRAN Past Events Fortran is an abbreviation of “Formula Translation”. It is the world’s first high-level programming language for computers, widely used in scientific and engineering computations. FORTRAN plays an important role in numerical, scientific, and engineering computations due to its unique features. (Versions prior to Fortran 90 are known as … Read more
On-board data bus technology is the interconnection technology used for onboard devices, subsystems, and modules. Understanding it from a computer perspective, various avionic devices are akin to individual microcomputers, while the bus serves as the channel and link connecting these microcomputers, forming a complete functional network for avionic equipment. Traditional bus technologies, represented by MIL-STD-1553b … Read more
