Great explanation of MQTT + Sparkplug B. Question: how does an HMI retrieve the current values when it comes online? It appears MQTT will only transmit when the value changes.

@industry40tvonline 3 жыл бұрын

Thanks for watching, and for the feedback Sumit. Great question. So it all depends on the MQTT broker implementation. Some brokers create DBIRTH messages on behalf of all connected devices whenever a new application such as HMI comes online. Such that the HMI that has just connected receives that initial DBIRTH message and then starts to wait for event change as well.

Great video! Where is the MQTT-broker located? Is it just a server hosted by hivemq? Can a MQTT-broker be a physical component located in a company and running as a server on its own? Or is it always provided by a company like hivemq?

@industry40tvonline 2 жыл бұрын

An MQTT broker can be hosted even on a device such as a Raspberry pi, or a company's on-prem server, and you can even host it in your own cloud-base VM. Thanks for your comment.

Very Informative Video Sir, btw I have a HMI that can be connected to MQTT. I plan to use MQTT to directly save data from hmi to PC, do you have tutorial video for that? Thank you very much

Hi Kudzai, from 23:40, you mentioned the "Last Will and Testament" but in the Sparkplug B Specification (see below) it is mentioned only once and not even once in the MQTT v3.1.1 specification. The below text says it is a MQTT v3.1.1 feature but how come that it is not mentioned in the MQTT specification? Do you maybe know? I have seen it is in the HiveMQ documentation, but I find it strange that its not mentioned in the MQTT specification and therefore, for me as a student, hard to understand. "The Sparkplug™ specification defines the use of the MQTT V3.1.1 “Last Will and Testament” feature to provide MQTT session state information to any other interested MQTT client in the infrastructure. The session state awareness is implemented around a set of defined “Birth” and “Death” Topic Namespace and Payload definitions in conjunction with the MQTT connection “Keep Alive” timer".

Thanks Kudzai. Can we do this on Nodered?

Isn't the broker setting up itself as a single point of failure? Is there a way we can implement redundancy?

@industry40tvonline 3 жыл бұрын

True the broker can be a single point of failure. You can employ a cluster of MQTT brokers installed on different machines acting as a single broker for redundancy.

@@industry40tvonline so will I have to subscribe to 2 topics with 2 instances for each data point? Won't that just increase the engineering effort and complexity of the application?

@industry40tvonline 3 жыл бұрын

@@dpdAL no, you won't have to do multiple subscriptions. The multiple brokers will be acting as a single logical broker, when one goes down, your traffic is automatically routed to other instances. Setting that up is not even hard, one-touch provisioning with most broker providers.
