CANopen是工業應用中最重要的通訊之一。然而受限於封閉式網路，難與工廠自動化系統整合，也不易進行遠端即時監控。除此，架設CANopen網路時常面臨開發時程長、除錯、維護不易等問題。本研究設計並實作了一個智慧型CANopen網路閘道器以解決上述問題。此一閘道器實現了CANopen網路的組態管理，網路管理，節點管理以及運行管理等功能，同時藉由內建的嵌入式Web伺服器，提供了遠端管理、監控功能。遠端使用者可透過網頁對CANopen網路新增或移除節點，甚至搜尋CANopen網路上的所有節點。在運行前確認網路狀態，得知每個節點的通訊能力、控制CANopen網路所有節點運行或停止，最後可控制數位點的輸出輸入、伺服馬達的運轉、以及讀取溫度模組的溫度值。本研究的貢獻在於提出了一個低成本、多功能的智慧型CANopen網路閘道器。在未來的工業物聯網、智慧型製造系統中，成為不可或缺的角色。;CANopen is one of the most crucial protocols in industrial applications. However, because CANopen is limited to the fieldbus network, integrating CANopen into automation equipment and conducting real-time remote monitoring is difficult. In addition, CANopen network management is challenging for several reasons such as complex configuration, time-consuming debugging, and maintenance. Therefore, this study proposes a smart CANopen gateway for solving these problems. This gateway implements the following functions: configuration management, network management, node management, and operation management of the CANopen network. Moreover, this gateway provides remote control and monitors the CANopen network through a built-in embedded web server. End users can manage the remote nodes through the web browser. Furthermore, this gateway supports the Auto Discovery nodes of the CANopen network, confirms network configurations, ascertains each node’s response time, and instructs each node to run or stop. Finally, this study uses test platforms to control and monitor digital input and output as well as server motors to determine the values of temperature sensors. The contribution of this study is a low-cost and multifunctional smart CANopen network gateway, which will be indispensable for the future industrial Internet of Things and intelligent manufacturing systems.
