資源簡介

B通過ActiveX的DLL與S7-1200/1500以太網通訊該類通訊組件適用于基于PC高級語言的工業自動化控制系統，用于PC與可編程控制器(PLC)、智能儀表等進行數據通訊。組件采用動態鏈接庫文件(*.DLL)的形式，在PC系統的項目工程里引用該組件，調用相應的屬性與方法函數，即可快速實現PC與PLC的數據高效交換。 DLL通訊組件無須安裝，直接復制到工程文件目錄，方便打包安裝部署；無須任何配置，直接調用函數，與應用開發無縫銜接；多年工程經驗的軟件團隊開發測試，經過本公司及客戶的海量實際應用檢驗，穩定可靠；采用穩定高效的內部協議，無須編寫PLC內部程序配合，直接訪問PLC的內存，通訊響應快速；內建動態管理的多獨立線程連接，同時支持外部應用的多線程結構調用；兼容WINDOWS系統下的所有開發環境，包括各種版本的VB.NET、C#、VC++，以及DEIPHI 、VB、LabView等；支持幾乎所有PLC的CPU自帶通訊口、通訊擴展模塊。
