電纜的機械和材料參數。因此用CAN-bus網(wǎng)絡(luò )替換RS-485網(wǎng)絡(luò )是非常方便節省成本的，原有的網(wǎng)絡(luò )布局不需要作任何的改動(dòng)，只需要用CAN節點(diǎn)來(lái)替換RS-485節點(diǎn)即可。此系統與KJ93礦井安全生產(chǎn)監控系統的最主要的差別就是把原有系統中的KJJ26信息傳輸接口、監控系統軟件和KJF20型工作站分別更換為CAN接口適配器、適用于CAN通信協(xié)議的監控系統軟件和基于CAN的工作站。

步驟2：安裝設備描述文件
將設備描述文件DM3E-556.xml復制到編程環(huán)境對應的安裝目錄下
OMRON\SysmacStudio\IODeviceProfiles\EsiFiles\UserEsiFiles
步驟3：添加主站和從站并配置參數
1）打開(kāi)Sysmac Studio的編程環(huán)境，新建工程，選擇對應型號的控制器和軟件版本
2）在配置和設置——EtherCAT 主站下添加節點(diǎn)目前變頻器市場(chǎng)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， 而國內變頻器絕大部分設備的出廠(chǎng)協(xié)議為Modbus RTU協(xié)議，此協(xié)議簡(jiǎn)單通用，但不夠智能，在接入到樓宇系統時(shí)，需要使用網(wǎng)關(guān)將其轉換成BACnet協(xié)議，再集成到樓控系統，這樣既增加集成商的設備成本（外購網(wǎng)關(guān)），又增加集成商的人力成本（現場(chǎng)工程師調試安裝網(wǎng)關(guān)及配置參數），而設備廠(chǎng)家要支持BACnet協(xié)議，必須持續投入長(cháng)時(shí)間人力物力的研發(fā)，為解決這一問(wèn)題，本公司推出一套使設備廠(chǎng)家快速接入BACnet系統的解決方案，設備廠(chǎng)家可在不到一個(gè)月的時(shí)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.
