摘要
近年來因為網路通訊技術的快速發展，網路控制系統又能降低成本，易於擴充和維修容易等，因此傳統的點對點控制已經漸漸的被網路控制系統取代，網路即時監控已演變為產業自動化監控的新趨勢。 隨著網路技術的進步及網路教學的興起，雖然有許多關於網路監控的主題研究，都是侷限在PC電腦與PLC主機之間的接點狀態或資料暫存器數值之單點或群組讀取、寫入或控制。PLC並無提供網路功能，目前可安裝網路卡或是增加通信模組以達到一對多台區域網路控制，其控制範圍也僅限制在PLC內建的元件接點。 本文希望藉由PLC通訊碼的側錄解析，利用VB 2008高階程式語言開發一套人機介面，其功能可模擬廠商提供的程式編輯軟體環境，對PLC主機完成程式寫入的動作。本文說明如何實現PLC之遠端操作，並進一步說明所完成的遠端操作系統未來作為一項平台，俾發展網路教學系統功能應用。

In recent years because of the rapid development of network communication technology, and a network control system has advantages of cost reduction, ease of expansion and maintenance, so the traditional point-to-point control has been gradually replaced by network control system. And network real time monitoring has been evolved into the new trend of industrial automatic monitoring. As the network technology progress and the rise of Web-based teaching, although there are many topics of study on network monitoring, they are still limited at the host state or data buffer value of read, write, or control between PC and PLC contact. Since the PLC itself does not provide network functionality, therefore now adapter card can be installed or communication interface can be increased to achieve network control function. Its control is only restricted at the PLC built-in single device contacts. In the premise of control, the program provided by manufacturer is required to edit the software to write PLC program into the host. This article shows by means of PLC communication code side recorded resolution, high-order VB 2008 programming language is used to develop a set of human-machine interface of which function could simulate vendor’s program editing software environment and write into the given host PLC. This article describes how to implement the remote operation of PLC, and further describes the remote operating system as a platform in the future, so that develops Web-based teaching system functionality.
