SCXI-1141電壓通道模塊,NI說明書文檔
電纜的機械和材料參數(shù)。因此用CAN-bus網(wǎng)絡(luò)替換RS-485網(wǎng)絡(luò)是非常方便節(jié)省成本的，原有的網(wǎng)絡(luò)布局不需要作任何的改動，只需要用CAN節(jié)點來替換RS-485節(jié)點即可。此系統(tǒng)與KJ93礦井安全生產(chǎn)監(jiān)控系統(tǒng)的最主要的差別就是把原有系統(tǒng)中的KJJ26信息傳輸接口、監(jiān)控系統(tǒng)軟件和KJF20型工作站分別更換為CAN接口適配器、適用于CAN通信協(xié)議的監(jiān)控系統(tǒng)軟件和基于CAN的工作站。

步驟2：安裝設(shè)備描述文件
將設(shè)備描述文件DM3E-556.xml復(fù)制到編程環(huán)境對應(yīng)的安裝目錄下
OMRON\SysmacStudio\IODeviceProfiles\EsiFiles\UserEsiFiles
步驟3：添加主站和從站并配置參數(shù)
1）打開Sysmac Studio的編程環(huán)境，新建工程，選擇對應(yīng)型號的控制器和軟件版本
2）在配置和設(shè)置——EtherCAT 主站下添加節(jié)點目前變頻器市場競爭已到白熱化程度，變頻器的通訊聯(lián)網(wǎng)功能已屬于必不可少項， 而國內(nèi)變頻器絕大部分設(shè)備的出廠協(xié)議為Modbus RTU協(xié)議，此協(xié)議簡單通用，但不夠智能，在接入到樓宇系統(tǒng)時，需要使用網(wǎng)關(guān)將其轉(zhuǎn)換成BACnet協(xié)議，再集成到樓控系統(tǒng)，這樣既增加集成商的設(shè)備成本（外購網(wǎng)關(guān)），又增加集成商的人力成本（現(xiàn)場工程師調(diào)試安裝網(wǎng)關(guān)及配置參數(shù)），而設(shè)備廠家要支持BACnet協(xié)議，必須持續(xù)投入長時間人力物力的研發(fā)，為解決這一問題，本公司推出一套使設(shè)備廠家快速接入BACnet系統(tǒng)的解決方案，設(shè)備廠家可在不到一個月的時間就支持BACnet MSTP協(xié)議。According to the three-layer structure of ibwp system, ibwpt is the method layer (middle layer), and ibwpt is the method, way and means to realize ibwp system engineering based on ibwp theory. Ibwpt is formed in the application of ibwp theory, so the method layer is based on ibwp theory both in fact and in logical structure, that is, ibwp theory is the theoretical basis of ibwpt: this can also be clearly seen from the study of the law of things' development. As mentioned above, ibwp theory mainly reveals the marginal disciplines formed by the intersection and integration of modern science such as information science and Architectural Science in the information age. This intersection and integration must have its own ways, ways, methods and means. These paths, ways, methods and means formed in the intersection and integration are ibwpt. Today's information age has created intelligent buildings and produced ibwp theory and technology. The relationship between ibwp theory and ibwpt is the relationship between basic theory and practical technical methods.
