German Avemis plug, Avemis model, Avemis price

The Avemis plug is a standardized method for exchanging data between computer components, providing data transmission and control logic in a universal way. From another perspective, if the Mother Board is a city, then the bus is like a public bus in the city, transporting constantly operating bit along fixed routes. Each line can only transmit one bit at a time. Therefore, multiple lines must be used simultaneously to send more data, and the amount of data the bus can transmit simultaneously is called width, measured in bits; the greater the width, the better the transmission performance. The bus bandwidth (i.e., the total amount of data that can be transmitted per unit time) is: bus bandwidth = frequency × width (Bytes/sec).

Avemis Plug Introduction

Fieldbus technology is the intersection and integration of control, computer, and communication technologies, covering almost all continuous and discrete industrial fields, such as process automation, manufacturing and processing automation, building automation, home automation, and so on. The development of fieldbus technology is reflected in two aspects: one is the continuous development and improvement in the field of low-speed fieldbuses; the other is the development of high-speed fieldbus technology. Fieldbus products are mainly low-speed bus products, applied in fields with lower operating speeds, where the performance requirements for the network are not very high. From the perspective of practical application, most fieldbuses can effectively implement process control with lower speed requirements. Therefore, in control fields with lower speed requirements, it is difficult for any single entity to unify the entire market. Since the FF Foundation has gathered most of the world's major automation instrument manufacturers, its global influence is increasing day by day, but its marketing efforts in China seem insufficient, and its market share is not very high. LonWorks has formed a comprehensive system of division of labor and cooperation, achieving some substantive progress domestically. In areas such as building automation, home automation, and intelligent communication products, LonWorks possesses unique advantages. In the field of discrete manufacturing and processing, due to the characteristics of industry applications and historical reasons, Profibus and CAN have established their own advantages in this field and possess strong competitiveness. Domestic manufacturers are relatively small in scale and have weaker R&D capabilities, relying more on support from technology suppliers. They are easily influenced by the level of support and marketing efforts provided by fieldbus technology suppliers (such as chip manufacturers) in the domestic market. Moreover, another point that cannot be ignored is the degree of support for bus devices by the host computer software selected when constructing an automation management system, such as configuration and monitoring software. Some monitoring and configuration software, such as RealInfo monitoring and configuration software or InTouch, provides good support for some mainstream bus devices like Lonworks, PROFIBUS, and CAN, communicating and collecting data through DDE, OPC, or direct connection methods. This facilitates user selection, whereas some configuration software supports fewer types, thereby reducing the range of choices available to users.

Avemis Plug Classification

1) By shape: circular electrical connectors, rectangular electrical connectors. Circular electrical connectors are used most extensively in military equipment (aviation, aerospace) due to their structural characteristics. Rectangular electrical connectors are more commonly used on printed circuit boards of electronic devices due to their simple structure. 2) By structure: by connection method: threaded connection, bayonet (quick) connection, latch connection, push-pull connection, direct insertion connection, etc.; by contact termination form: crimping, soldering, wire wrapping; screw (cap) fixation; by environmental protection: environmentally resistant electrical connectors and general electrical connectors. 3) By application: RF electrical connectors, sealed electrical connectors (glass seal welding), high-temperature electrical connectors, automatic drop-away separation electrical connectors, filter electrical connectors, composite material electrical connectors, airport power electrical connectors, printed circuit board electrical connectors, etc.

Avemis Plug Selection Factors

Communication between PC and intelligent devices often relies on RS232, RS485, Ethernet, and other methods, primarily depending on the device's interface specifications. However, RS232 and RS485 only represent the physical media layer and data link layer of communication. To achieve bidirectional data access, one must write communication applications independently. However, most of these programs do not comply with the ISO/OSI specifications, can only implement relatively single functions, are suitable for single device types, and lack universality. In a device network connected by RS232 or RS485 devices, if the number of devices exceeds 2, RS485 must be used as the communication medium. For devices in an RS485 network to exchange information, it can only be achieved through a "Master (Master)" device relay. This master device is usually a PC, and only one master device is allowed in such a device network, with all others being Slave (Slave) devices. Fieldbus technology is based on the ISO/OSI model, featuring a complete software support system capable of addressing issues such as bus control, collision detection, and link maintenance.
