TDM1.2-050-300全部裝置由一個(gè)中央控制室（Central Control Room CCR）和十四個(gè)外站（Outstation）構(gòu)成，中央控制室用于監(jiān)視管理所有的工藝裝置和公用設(shè)施，是聯(lián)合裝置中最關(guān)鍵的部分。每個(gè)裝置會(huì)有若干個(gè)外站，所有現(xiàn)場(chǎng)儀表信號(hào)都先傳送到外站，再?gòu)耐庹舅偷街醒肟刂剖?。DCS、SIS、F&G系統(tǒng)的控制器都放在外站里，每個(gè)外站都有一個(gè)操作員，平常不設(shè)人員值班，僅僅是用來(lái)方便現(xiàn)場(chǎng)操作人員就近使用的，如進(jìn)行儀表調(diào)試（包括回路測(cè)試）等。 二、FF現(xiàn)場(chǎng)總線特點(diǎn) 基金會(huì)現(xiàn)場(chǎng)總線（Foundation Fieldbus）通常稱為FF現(xiàn)場(chǎng)總線，它分為H1和H2兩級(jí)總線。H1采用符合IEC 61158-2標(biāo)準(zhǔn)的現(xiàn)場(chǎng)總線物理層；H2則采用高速以太網(wǎng)為其物理層。 H1現(xiàn)場(chǎng)總線物理層的主要電氣特性如下：采用位同步數(shù)字化傳輸方式；傳輸TDM1.2-050-300波特率為31.25kbit/s；驅(qū)動(dòng)電壓9～32V DC；信號(hào)電流±9mA；電纜型式屏蔽雙絞線；接線拓?fù)浣Y(jié)構(gòu)可采用線形、樹(shù)形、星形或者符合形；電纜長(zhǎng)度小于等于1900m（無(wú)中繼器時(shí)）；分支電纜的長(zhǎng)度30～120m；掛界設(shè)備數(shù)量小于等于32臺(tái)（無(wú)中繼器時(shí)）；可用中繼器小于等于4臺(tái)；適用防爆方法有本質(zhì)安全防爆方法等。 三、FF現(xiàn)場(chǎng)總線的網(wǎng)絡(luò)構(gòu)成 1、網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu) 現(xiàn)場(chǎng)采用雞爪形（Chickens Foot）拓?fù)浣Y(jié)構(gòu)，每個(gè)段僅有一個(gè)雞爪，在SECCO項(xiàng)目中不允許使用復(fù)式雞爪形拓?fù)浣Y(jié)構(gòu)。 2、總線供電 H1現(xiàn)場(chǎng)總線在一根屏蔽雙絞線電纜上完成對(duì)多臺(tái)現(xiàn)場(chǎng)儀表的供電和雙向數(shù)字通訊。控制系統(tǒng)所配備的H1網(wǎng)卡通常只負(fù)責(zé)與現(xiàn)場(chǎng)儀表的雙向通訊。而總線的供電則需由專門的FF配電器完成。 H1總線以段為單位，每塊H1網(wǎng)卡有兩個(gè)端口，每個(gè)端口連接一個(gè)段，而每一段需配一臺(tái)FF配電器?？偩€的兩端還需各配一個(gè)終端電阻，以消除高頻信號(hào)的回聲。 現(xiàn)場(chǎng)總線網(wǎng)絡(luò)有許多需要外置電源供電的二線制現(xiàn)場(chǎng)設(shè)備，一般工作電壓為9～32V，典型為24V。每臺(tái)設(shè)備吸收電流在10～25mA之間。為了確保足夠的電壓維持運(yùn)行，就必須在現(xiàn)場(chǎng)總線區(qū)域配置時(shí)知道每臺(tái)設(shè)備的功耗、位置、電纜的阻抗和電源電壓等情況，分別計(jì)算出干線、支線上的電壓降，最終得到現(xiàn)場(chǎng)設(shè)備上的電壓。 3、電纜線 現(xiàn)場(chǎng)總線的物理信號(hào)、終端、電源、本質(zhì)安全等與常規(guī)儀表不同，TDM1.2-050-300兩者使用的電纜必須加以區(qū)別?？晒┑耐ㄓ嵥俾蕿?1.25kb/s的H1現(xiàn)場(chǎng)總線的電纜線類型、規(guī)格、最大長(zhǎng)度等，應(yīng)根據(jù)工程需要來(lái)選擇電纜。一般首選A型用于新裝置；B型可作為替代器；C型、D型僅用于改造的裝置。 在工程中，必須注意電纜線的屏蔽與接地，首選A、B型屏蔽電纜。C、D型電纜也可將導(dǎo)線穿于金屬管中進(jìn)行屏蔽，使用屏蔽電纜后，需將各支線與干線的屏蔽連接起來(lái)，然后集中一起進(jìn)行接地；必須注意電纜線與設(shè)備連接的極性TDM1.2-050-300問(wèn)題，因此，現(xiàn)場(chǎng)總線使用的曼徹斯特信號(hào)是交替電壓，每bit改變1次或兩次極性。在非供電網(wǎng)絡(luò)中只存在這種交流電壓。
