German olympus plug olympus model olympus price

olympus plugs are a standardized method for exchanging data (data) between computer components, providing data transmission and control logic in a universal way. From another perspective, if the motherboard (Mother Board) is a city, then the bus (bus) is like a public bus in the city, transporting bits (bit) that operate back and forth along fixed routes. These lines 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 (width), measured in bits; the greater the bus 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).

olympus 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 rates, where the requirements for network performance are not very high. From the perspective of actual application, most fieldbuses can achieve process control with lower rate requirements quite well. Therefore, in control fields with lower rate 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 smart 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 that when constructing an automation management system, the choice of host computer, such as the level of support for bus devices by configuration software, plays a role. Some monitoring and configuration software, such as KingView 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.

olympus Plug Classification

Industrial bus networks can be categorized into three types: 485 networks, HART networks, and FieldBus fieldbus networks. 485 Network: RS485/MODBUS is a popular industrial networking method, characterized by simple and convenient implementation, and there are particularly many instruments supporting RS485. Instrument manufacturers have also turned to support RS485/MODBUS for the simple reason that RS485 conversion interfaces are not only cheap but also diverse. At least in the low-end market, RS485/MODBUS will remain the primary industrial networking method. HART Network: HART is a transitional bus standard proposed by Emerson, mainly characterized by superimposing digital signals on 4-20 mA current signals. However, this protocol is not truly open; one must join its foundation to obtain the protocol, which requires a certain fee. HART technology is mainly monopolized by several large foreign companies. In recent years, some domestic companies have also been working on it, but they have not yet reached the level of foreign companies. Many smart instruments come with [HART round card] and support HART communication functions. However, from the domestic perspective, this function has not been truly used for device networking and monitoring; at most, handheld configurators are used to set parameters. In the long run, due to low HART communication rates and difficulties in networking, the application of HART instruments will show a downward trend. FieldBus Fieldbus Network: Fieldbus is one of the hot technologies in the automation field today, hailed as the computer LAN of the automation field. Its emergence marks the beginning of a new era in automation control technology. Fieldbus is a digital, serial, multi-station communication network connecting instruments at the control site with control devices in the control room. Its key hallmark is the ability to support bidirectional, multi-node, bus-style fully digital communication. Fieldbus technology has become a hotspot in the international development of automation and instrumentation. Its emergence has brought revolutionary changes to traditional control system structures, further advancing automatic control systems towards "intelligence, digitization, informatization, networking, and decentralization," forming a new type of networked communication fully distributed control system—Fieldbus Control System FCS (Fieldbus Control System). However, fieldbus has not yet formed a truly unified standard. Multiple standards such as ProfiBus, CANbus, and CC-Link coexist, each with its own niche. When unification will occur is uncertain. There are relatively few types of instruments supporting fieldbus, limited choices, higher prices, and smaller usage volumes.

PC communication with smart devices mostly relies on RS232, RS485, Ethernet, etc., depending mainly on the device's interface specifications. However, RS232 and RS485 only represent the physical media layer and link layer of communication. To achieve bidirectional data access, one must write communication applications oneself, but most such programs do not comply with ISO/OSI specifications, can only achieve 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 relay by a "Master (Master)" device. This master device is usually 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, having a complete software support system capable of solving problems such as bus control, conflict detection, and link maintenance.
