在60年代，汽車生產(chǎn)流水線的自動(dòng)控制系統(tǒng)基本上都是由繼電器控制裝置構(gòu)成的。當(dāng)時(shí)汽車的每一次改型都直接導(dǎo)致繼電器控制裝置的重新設(shè)計(jì)和安裝。隨著生產(chǎn)的發(fā)展，汽車型號(hào)更新的周期愈來(lái)愈短，這樣，繼電器控制裝置就需要經(jīng)常地重新設(shè)計(jì)和安裝，十分費(fèi)時(shí)，費(fèi)工，費(fèi)料，甚至阻礙了更新周期的縮短。為了改變這一現(xiàn)狀，美國(guó)通用汽車公司在1969年公開招標(biāo)，要求用新的控制裝置取代繼電器控制裝置，并提出了十項(xiàng)招標(biāo)指標(biāo)，即：

(1）編程方便，現(xiàn)場(chǎng)可修改程序；

(2）維修方便，采用模塊化結(jié)構(gòu)；

(3）可靠性高于繼電器控制裝置；

(4）體積小于繼電器控制裝置；

(5）數(shù)據(jù)可直接送入管理計(jì)算機(jī)；

(6）成本可與繼電器控制裝置競(jìng)爭(zhēng)；

(7）輸入可以是交流115V；

(8）輸出為交流115V，2A以上，能直接驅(qū)動(dòng)電磁閥，接觸器等；

(9）在擴(kuò)展時(shí)，原系統(tǒng)只要很小變更；

(10）用戶程序存儲(chǔ)器容量至少能擴(kuò)展到4K。
