BK9103|PROFINET總線耦合器
1.
BK9103總線耦合器將PROFINET RT與模塊化、可擴(kuò)展的電子接線端子連接起來。一個(gè)單元由一個(gè)總線耦合器、1到64個(gè)端子（255個(gè)帶K總線擴(kuò)展）和一個(gè)端部端子組成。
總線耦合器識(shí)別它們所連接的端子，并自動(dòng)將輸入和輸出分配給過程圖像的單詞。BK9103總線耦合器支持10 Mbit/s和100 Mbit/s以太網(wǎng)。通過普通RJ45連接器連接。IP地址在DIP開關(guān)上設(shè)置（偏移到可自由選擇的起始地址）。在具有DHCP（用于將邏輯IP地址分配給物理節(jié)點(diǎn)地址[MAC-ID]的服務(wù)）的網(wǎng)絡(luò)中，總線耦合器從DHCP服務(wù)器獲得其IP地址。
BK9103包含一個(gè)3端口交換機(jī)。兩個(gè)端口在RJ45連接器上進(jìn)行外部操作，可以使用。因此，I/O站可以配置為線路拓?fù)?，而不是?jīng)典的星形拓?fù)?。在許多應(yīng)用中，這大大減少了布線工作量和布線成本。兩個(gè)耦合器之間的zui大距離為100米。多達(dá)20個(gè)BK9103總線耦合器是可級(jí)聯(lián)的，因此可以實(shí)現(xiàn)2公里的線路長(zhǎng)度。
PROFINET是PNO（PROFIBUS Nutzerorganization）的開放式工業(yè)以太網(wǎng)標(biāo)準(zhǔn)。TCP/IP等國際公認(rèn)的IT標(biāo)準(zhǔn)用于通信。PROFINET RT描述了控制器和現(xiàn)場(chǎng)設(shè)備之間的數(shù)據(jù)交換，可用于標(biāo)準(zhǔn)以太網(wǎng)。商用交換機(jī)用于網(wǎng)絡(luò)目的。
