EtherCAT全數位運動控制平台發展與應用

從傳統工業演變至自動化工業，廠區自動化設備的擴增提升了製品的產量與精密度，也讓硬體線路配置變得更加繁複，運用乙太網路控制自動化技術（EtherCAT）進行控制與網路通訊，不僅可將原本複雜的佈線改以網路線取代，即可進行高速資料與控制訊息的傳輸，提升資料的正確性與抗干擾能力；在5G來臨的時代，工廠將會迎來重大變革，結合大數據與IoT形成智慧型工廠，使得資料傳輸網路化成為重要的議題。本文將介紹工研院機械所以EtherCAT技術整合運動控制函式庫，開發出全數位運動控制平台（EMP），並結合開放式通訊協定OPC UA與MQTT之相關應用。

The evolution from traditional industry to an automate industry caused the automation equipment to expand, which improved productivity and precision of the product, However it also made the wiring more complicated. By using Ethernet for Control Automation Technology (EtherCAT), we can replace the very complex wiring with Ethernet cable and to reach high-speed control and transmission of data; Thus, data accuracy and anti-interference ability can be enhanced. In the era of 5G, there is an essential revolution in the factory in combining the use of big data and IoT to build a smart factory; Therefore, the data transmission network will be a critical issue. The MMSL in the Industrial Technology Research Institute integrated EtherCAT technology and motion control command library to develop an EtherCAT Motion Control Platform (EMP). This article will introduce the development and application of EMP integrating with open communication protocol OPC UA and MQTT.
