A06B-6151-H030#H580被用于需要高可靠性、高穩(wěn)定性和高性能的系統(tǒng)中，以滿足對(duì)實(shí)時(shí)性、數(shù)據(jù)處理能力和擴(kuò)展性的要求。
VME總線標(biāo)準(zhǔn)是一種高性能、高可靠性的計(jì)算機(jī)總線標(biāo)準(zhǔn)，具有以下特點(diǎn)：
模塊式設(shè)計(jì)：VME總線系統(tǒng)由多個(gè)功能模塊（稱為VME模塊）組成，每個(gè)模塊都具有自己的處理器、內(nèi)存、I/O接口等。這種模塊化設(shè)計(jì)使得用戶可以輕松地將不同功能模塊組合在一起，創(chuàng)建出滿足特定需求的系統(tǒng)。
高可靠性：VME總線的機(jī)械接口采用后插式接口技術(shù)，使得設(shè)備板卡能夠快速地更換。此外，VME模塊通常采用金屬化封裝，具有良好的抗振和電磁干擾性能，從而保證系統(tǒng)的穩(wěn)定性和可靠性。
多節(jié)點(diǎn)共享：VME總線支持多節(jié)點(diǎn)并行共享，方便系統(tǒng)中各個(gè)節(jié)點(diǎn)之間的數(shù)據(jù)交互。這種并行共享機(jī)制可以大大提高系統(tǒng)的數(shù)據(jù)傳輸效率和處理能力。
高性能：VME總線采用DMA（Direct Memory Access，直接內(nèi)存訪問）技術(shù)，支持大量的數(shù)據(jù)傳輸。同時(shí)，VME總線的地址線長(zhǎng)度可以達(dá)到40位或64位，支持更大的內(nèi)存尋址空間和更高的數(shù)據(jù)傳輸速率。

A06B-6151-H030#H580

The A06B-6151-H030#H580 is used in systems that require high reliability, high stability and high performance to meet the requirements for real-time performance, data processing capabilities and scalability.
VME bus standard is a high performance, high reliability computer bus standard, with the following characteristics:
Modular design: The VME bus system consists of a number of functional modules (called VME modules), each module has its own processor, memory, I/O interface, etc. This modular design allows users to easily combine different functional modules to create systems that meet specific needs.
High reliability: The mechanical interface of the VME bus adopts rear plug interface technology, which enables the equipment board to be replaced quickly. In addition, VME modules are usually metallized and have good vibration and electromagnetic interference resistance, thus ensuring system stability and reliability.
Multi-node sharing: The VME bus supports multi-node parallel sharing, which facilitates the data interaction between each node in the system. This parallel sharing mechanism can greatly improve the data transmission efficiency and processing capability of the system.
High performance: VME bus adopts DMA (Direct Memory Access) technology to support a large amount of data transmission. At the same time, the address line length of the VME bus can reach 40 bits or 64 bits, supporting larger memory addressing space and higher data transfer rates.
