控制處理機(jī)(CP60)：
控制處理機(jī)是一個可選的容錯站，和與之相連的現(xiàn)場總線組件(FBM)一起，可按組態(tài)好的控制方案對過程進(jìn)MCS40A-0015-5A3-4-00 模塊
*某些需要快速處理的回路的模擬量控制可放在FBM組件中處理，其處理速度為10-50毫秒（可組態(tài)），開關(guān)量控制也可放在FBM組件中處理，其處理速度為2-5毫秒。
I/A Series 通訊處理機(jī)
通訊處理機(jī)(COMM10), 它提供了四個 RS232-C 通訊接口，最多可連接四臺136列中英文打印機(jī)或彩色噴墨打印機(jī), 其異步通訊速率為9.6kbps。可分別打印報表及報警, 并可組態(tài)為互為后備。
通訊處理機(jī)給用戶提供下列功能：
*標(biāo)準(zhǔn)出錯和報警報文打印功能：
任何能夠產(chǎn)生報文的系統(tǒng)站，都有一個可能作輸出的I/O設(shè)備表。用戶可以按照它們的邏輯名稱去這些設(shè)備。如向通訊處理機(jī)傳送許多報文，則它們就地排隊，并按優(yōu)先級從處理機(jī)傳送到各特定設(shè)備，這就保證了對高優(yōu)先級的報警報文的迅速服務(wù)。
*報表和大批量打印機(jī)處理
如果設(shè)備被組態(tài)成為可鎖定的，報表就可以完整地打印到結(jié)束，在打印時，不混雜報警報文。為了及時地輸出，其他報文，包括報警，可改道送到后備設(shè)備。當(dāng)報表結(jié)束時，設(shè)備就解鎖，按優(yōu)先級次序的常規(guī)處理方法繼續(xù)。如果設(shè)備沒有定作可鎖定的，則較高優(yōu)先等級的報警報文將與報表輸出混雜在一起，而且不發(fā)生報文改道。
*報文后備
通訊處理機(jī)包含一個后備機(jī)構(gòu)，該后備機(jī)構(gòu)是用于設(shè)備故障或上鎖時，給未打印報文規(guī)定到后備設(shè)備的路徑。這個后備設(shè)備可以在就地通訊處理機(jī)中，也可在遠(yuǎn)方的通訊處理機(jī)中。通過組態(tài)過程，對于每一個連接的設(shè)備，可以規(guī)定第一后備設(shè)備和第二后備設(shè)備。在檢測到設(shè)備故障時，由通訊處理機(jī)自動通知執(zhí)行后備路經(jīng)進(jìn)程。
