- 41:00 - Q&A
- 41:28 - Can you share information on MQTT basics, Sparkplug basics to get started?
- 42:16 - What requirements are there for MQTT brokers to support OPC UA PubSub? Is there a specific version of MQTT, Sparkplug, etc.? Or can any MQTT broker work with OPC UA PubSub?
- 45:06 - Could you please explain a bit more regarding Kafka & how it connects to the broker & streams data to the Azure Event Hubs?
- 46:57 - Can we publish the code that is used for the demonstration to get a hub? The OPC UA server that we are using is KEPServerEX or is it another Node.js application?
- 49:29 - Could you please provide more information on the comparison of MQTT vs OPC UA for real-time communication?
- 54:22 - Is Node-Red supporting OPC UA server PubSubs? Is there a similar setup that will work with AWS?
- 56:29 - Does it make sense to use a Sparkplug with an OPC UA PubSub?
- 57:05 - Is there a way we can publish the MQTT information straight to the IoT hub?
- 57:50 - What field did you use for the timestamps in TSI? Have you seen any problems with aligning the timestamps from the sensor collector data to Azure?
- 58:49 - Is the dark net OPC UA to MQTT network Program available for public use?
- 59:23 - Does the Analytics work in real time?
Webinar Overview
The OPC UA Client/Server model of communication is useful for closed-loop command and control interactions between field devices and applications at the industrial edge, especially where the number of connections is not very high. It falls short when it comes to integrating your production data with external systems such as cloud-based analytics and other IT applications that know nothing about OPC UA.
As the number of connected components increases rapidly in Industrial IoT scenarios, this model cannot scale to meet such connectivity demands. The solution to these challenges is to use OPC UA’s PubSub communication model with an MQTT message broker.
Watch Kudzai Manditereza to learn how to go about it as we describe and demonstrate an end-to-end implementation of this solution. Additionally, read the blog The Key Differences Between OPC UA And MQTT Sparkplug.
