PLC自動控制系統經過10多年生產實踐，并經多次改進后正常運行至今，運行效果良好，*地提高了生產效率，確保生產指標。

同時降低了工人的勞動強度，減少崗位定員，降低了人力資源成本；改善了生產作業環境，減少了設備故障，降低了設備維護成本，深受崗位操作人員歡迎。

據統計，該系統每年直接或間接為企業創效50多萬元，并取得良好的社會效益。

工業界對于分布式控制系統（DCS）與可編程邏輯控制器（PLC）兩者孰優孰劣的爭論已經持續了至少40年。然而，隨著技術的發展，爭論并未停止。由于兩者功能特性越來越接近，價格差異也在縮小，曾經一度很清晰的選擇，現在似乎變得越來越模糊。要想理解這兩者之間的爭論，就一定要明確這兩種平臺之間的根本性差異。

要想理解這兩者之間的爭論，就一定要明確這兩種平臺之間的根本性差異。例如，DCS體系結構源自一種完整的系統方法，其焦點在于基于網絡實現分布式控制，協助作業人員監視并操控工廠中的任何一個區域。通過高性能的確定性網絡實現*、同步并且完整的過程數據正是DCS體系結構的核心。
