German Exsys plug Exsys model Exsys price

Exsys plug is a standardized method for exchanging data (data) between computer components, providing data transmission and control logic to each component in a universal way. From another perspective, if the motherboard (Mother Board) is a city, then the bus is like a public bus (bus) in the city, capable of transmitting bits (bit) that operate back and forth along fixed routes. These lines can only be responsible for transmitting one bit at a time. Therefore, multiple lines must be used simultaneously to send more data, and the number of data items that 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).

Exsys plug composition

The fieldbus control system consists of three parts: measurement system, control system, and management system, with the hardware and software of the communication part being its most distinctive feature. 1) Fieldbus control system: Its software is an important part of the system. Control system software includes configuration software, maintenance software, simulation software, device software, and monitoring software. First, select development configuration software and control operation human-machine interface software. Through the configuration software, complete the connections between function blocks, select function block parameters, and perform network configuration. During network operation, collect data from the system in real time, process data, and perform calculations. Optimize control and logical control alarms, monitoring, display, reports, etc. 2) Fieldbus measurement system: Its characteristics include multi-variable high-performance measurement, enabling measuring instruments to have computing capabilities and other functions. Due to the use of digital signals, it has high resolution, high accuracy, strong anti-interference, and strong anti-distortion capabilities. It also has status information of instrument equipment, allowing adjustments to the processing process. 3) Equipment management system: It can provide diagnostic information, management information, equipment operating status information (including smart instruments), and equipment manufacturing information provided by manufacturers. For example, Fisher—Rosemoune company launched the AMS management system, which is installed in the main computer to complete management functions, forming a comprehensive management system information library for field devices. Based on this, reliability analysis and predictive maintenance of equipment are realized, changing the passive management mode to a predictable management and maintenance mode. The AMS software is based on a T type structure with the field server as the platform, supporting modular, rich-function application software on the field server to provide users with a graphical interface. 4) Bus system computer service mode: The client/server mode is a relatively popular network computer service mode. The server represents the data source (provider), and the application client represents the data user, which obtains data from the data source and further processes it. The client runs on a PC or workstation. The server runs on a minicomputer or mainframe, using the intelligence, resources, and data of both parties to complete tasks. 5) Database: It can organically and dynamically store large amounts of data and applications, achieving full data sharing and cross-access with high independence. Industrial equipment parameters change continuously during operation, with large data volumes and high real-time requirements for operation and control. Therefore, a distributed and real-time database system with mutual access operations is formed. Mature options available on the market include relational databases such as Oracle, sybas, Informix, SQL Server; and real-time databases such as Infoplus, PI, ONSPEC. 6) Network system hardware and software: Network system hardware includes system management hosts, servers, gateways, protocol converters, hubs, user computers, and underlying intelligent instruments. Network system software includes network operating software such as NetWarc, LAN Mangger, Vines, server operating software such as Lunix, os/2, Window NT, application software databases, communication protocols, network management protocols, etc.

Exsys plug features

Field control equipment has communication functions, facilitating the construction of factory bottom-layer control networks. Open and consistent communication standards make the system open and devices interoperable. Standardization of function blocks and structures makes devices with the same function interchangeable. Downgrading control functions to the field gives the control system structure a high degree of dispersion. Fieldbus brings automatic control equipment and systems into the ranks of information networks, opening up broader fields for their application; multiple control devices can be connected on a pair of twisted pairs, saving installation costs; reducing maintenance expenses; improving system reliability; and providing users with more flexibility in system integration initiatives.

Exsys plug data exchange method

Data Bus (DataBus). It standardizes methods for data sharing and exchange in homogeneous and heterogeneous systems within a large integrated application system, serving as a standard for data exchange between systems. It can be used to transmit information between microprocessors and memory, and between microprocessors and input/output interfaces. The width of the data bus is an important indicator determining computer performance. Most microcomputer data buses are 32-bit or 64-bit. 1) Business entity data exchange: Each subsystem has a business entity layer in its architectural hierarchy. The data exchange mechanism establishes a layer transparent to all application systems at the business entity layer. Between subsystems, regardless of the specific technical implementation, sharing and interaction can occur through the business entity layer, establishing a structure for continuous integration and business expansion between subsystems, thereby realizing a scalable, complete, integrated information system. 2) WebService data exchange: It is a Web service standard. Web services provide solutions for sharing and exchanging data between heterogeneous systems and can also be used for data sharing and exchange using unified interface standards in product integration.
