PLC自動(dòng)控制系統(tǒng)經(jīng)過(guò)10多年生產(chǎn)實(shí)踐，并經(jīng)多次改進(jìn)后正常運(yùn)行至今，運(yùn)行效果良好，*地提高了生產(chǎn)效率，確保生產(chǎn)指標(biāo)。
同時(shí)降低了工人的勞動(dòng)強(qiáng)度，減少崗位定員，降低了人力資源成本；改善了生產(chǎn)作業(yè)環(huán)境，減少了設(shè)備故障，降低了設(shè)備維護(hù)成本，深受崗位操作人員歡迎。
據(jù)統(tǒng)計(jì)，該系統(tǒng)每年直接或間接為企業(yè)創(chuàng)效50多萬(wàn)元，并取得良好的社會(huì)效益。
工業(yè)界對(duì)于分布式控制系統(tǒng)（DCS）與可編程邏輯控制器（PLC）兩者孰優(yōu)孰劣的爭(zhēng)論已經(jīng)持續(xù)了至少40年。然而，隨著技術(shù)的發(fā)展，爭(zhēng)論并未停止。由于兩者功能特性越來(lái)越接近，價(jià)格差異也在縮小，曾經(jīng)一度很清晰的選擇，現(xiàn)在似乎變得越來(lái)越模糊。要想理解這兩者之間的爭(zhēng)論，就一定要明確這兩種平臺(tái)之間的根本性差異。
要想理解這兩者之間的爭(zhēng)論，就一定要明確這兩種平臺(tái)之間的根本性差異。例如，DCS體系結(jié)構(gòu)源自一種完整的系統(tǒng)方法，其焦點(diǎn)在于基于網(wǎng)絡(luò)實(shí)現(xiàn)分布式控制，協(xié)助作業(yè)人員監(jiān)視并操控工廠中的任何一個(gè)區(qū)域。通過(guò)高性能的確定性網(wǎng)絡(luò)實(shí)現(xiàn)*、同步并且完整的過(guò)程數(shù)據(jù)正是DCS體系結(jié)構(gòu)的核心。
