PLC控制器是系統(tǒng)控制的中心,采集系統(tǒng)的全部工況信號(hào),實(shí)時(shí)控制相關(guān)的設(shè)備動(dòng)作;同時(shí)監(jiān)視生產(chǎn)過(guò)程參數(shù)和設(shè)備運(yùn)行狀態(tài),當(dāng)危險(xiǎn)工況出現(xiàn)時(shí),及時(shí)發(fā)出聲光報(bào)警,當(dāng)極限工況出現(xiàn)時(shí),聯(lián)鎖保護(hù)設(shè)備,保障生產(chǎn)過(guò)程安全。為此,我們選擇了以產(chǎn)品可靠性高著稱的羅克韋爾自動(dòng)化公司的新一代控制平臺(tái):A-B ControlLogix系列,同時(shí)考慮采用雙CPU模塊冗余,進(jìn)一步提高系統(tǒng)可靠性,避免因故障出現(xiàn)所引起的生產(chǎn)停頓或安全事故。
三、兩種雙CPU冗余方式的比較
ControlLogix提供有兩種CPU冗余解決方法,一種為純硬件冗余,另一種為軟件冗余。
硬件冗余的方法,是將兩個(gè)CPU模塊插在不同的兩個(gè)機(jī)架上,每個(gè)機(jī)架上除了CPU模塊,還要有通訊模塊CNBR、熱備模塊SRM和兩個(gè)熱備模塊間的連接光纜
