“Netvox began developing LoRa-based products six months ago, successfully converting eight Zigbee sensors to use Semtech’s LoRa Technology,” said Kent Shen, Vice President at Netvox. “We are very pleased to have received a great level of interests with our LoRa-based demonstrations at the LoRa Alliance’s™ 9th All Members Meeting in Suzhou and have decided to convert all 250 Zigbee products to adopt the open LoRaWAN protocol.”
“Netvox recognized the benefits and opportunities of expanding its IoT products to utilize Semtech’s LoRa Technology, as more verticals are looking for long-range, low-power capabilities and solutions for their IoT applications,” said Mike Wong, Vice President of Semtech’s Wireless and Sensing Products Group. “Semtech’s LoRa Technology is becoming the technology of choice for building IoT applications and Netvox should play an important role in making our world a smarter planet.”

OPC UA 學習筆記 在工業智慧自動控制的領域中，不但眾所熟知的PAC、PLC(Programmable Logic Controller)、PC Base controller、DDC等控制設備和小型HMI (Human-Machine Interface)或大型SCADA(Supervisory Control And Data Acquisition)工業軟體，需要在不同種類的工業控制器，網絡系統中運作。 而在製程自動化的領域，當希望把DCS(Distributed Control System)中所有的製程數據傳送到上層的MES生產流程與ERP企業資源管理系統時，還必須按照各個供應商的機種開發特定的通訊介面應用程式，才能達成資料整合，並協助企業決策及提升效能，這在今天所推廣的IIOT工業物聯網趨勢，萬物互聯的效應的帶動下，顯得不合時宜。 1996年8月由OPC協會制定OPC(OLE for Process Control)的工業標準，是由全球首屈一指的自動化軟、硬體公司與微軟(Microsoft)公司共同合作的技術結晶，採用主從式(Client-Server)的架構處理資訊傳輸，也就是藉由一個稱之為OPC Server介面的元件，建立與OPC Client交換資訊的管道，達成資料傳遞與分享的功能。 PAC (Programmable Automation Controller,) PLC Programmable Logic Controller DDC HMI (Human-Machine Interface) SCADA (Supervisory Control And Data Acquisition) DCS (Distributed Control System) MES ERP OPC (OLE for Process Control) OLE OPC UA (OPC Unified Architecture) 一次補一堆名詞 OPC foundation 介紹影片 參加OPC foundation 會員可以有測試tool 來檢驗是否合乎標準。 後續要要注意的有 OPC UA 規範 / 相關的 opensource有哪些 / 可以溝通後那要用語言資料交換？ 想了解哪些OPC UA 相關的題目，歡迎留言，持續更新 !! 2019 /06 QN
