||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.|
