·雙絞線：是綜合布線系統(tǒng)中zui常用的一種傳輸介質(zhì)，尤其在星型網(wǎng)絡(luò)拓?fù)渲?，雙絞線是*的布線材料。雙絞線電纜中封裝著一對(duì)或一對(duì)以上的雙絞線，為了降低信號(hào)的干擾程度，每一對(duì)雙絞線一般由兩根絕緣銅導(dǎo)線相互纏繞而成。雙絞線可分為非屏蔽雙絞線（UTP）和屏蔽雙絞線（STP）兩大類。其中，STP又分為3類和5類兩種，而UTP分為3類、4類、5類、超5類四種，同時(shí)，6類和7類雙絞線也會(huì)在不遠(yuǎn)的將來(lái)運(yùn)用于計(jì)算機(jī)網(wǎng)絡(luò)的布線系統(tǒng)。
 
·RJ-45接頭：每條雙絞線兩頭通過(guò)安裝RJ-45連接器（俗稱水晶頭）與網(wǎng)卡和集線器（或交換機(jī)）相連。
 
·同軸電纜：是由一根空心的圓柱網(wǎng)狀銅導(dǎo)體和一根位于中心軸線的銅導(dǎo)線組成，銅導(dǎo)線、空心圓柱導(dǎo)體和外界之間用絕緣材料隔開。與雙絞線相比，同軸電纜的抗*力強(qiáng)，屏蔽性能好，所以常用于設(shè)備與設(shè)備之間的連接，或用于總線型網(wǎng)絡(luò)拓?fù)渲?。根?jù)直徑的不同，又可分為細(xì)纜和粗纜兩種。
 

I/A Series Batch 5.3 I/A Series Batch 8.1 Suite See below for I/A Batch Advantage #s Foxboro's I/A Series Batch Suite is the industry's most functionally complete family of unified batch automation components. It provides a true scalable client/server environment with capabilities for materials tracking and traceability, short-term scheduling, dynamic batch and equipment management, batch history, and reporting. This powerful array of features produces key benefits that dramatically improve your plant's economic performance. The I/A Series Batch Suite architecture offers a scalable solution with the added feature of high availability. It can be implemented in a single node and grow to encompass multiple nodes. A multi-node system can be connected through an enterprise Ethernet network and interfaced to an ERP system such as SAP. Multi node has more operator stations (runtime clients).
