Bring in data from MQTT to ctrlX Data Layer or OPC UA

Bring in data from MQTT to ctrlX Data Layer or OPC UA

Hi,

I am currently using a sensor that publishes data via MQTT to a HiveMQ MQTT Broker.

From ctrlX Node-RED app I created a HiveMQ MQTT Broker and used the mqtt subscribe node to subscribe to the topics and created a simple monitoring dashboard.

Next, I wanted to try to visualize the sensor data in webIQ but the problem is webIQ is using OPC UA, and the sensor data is not available in OPC UA/ ctrlX Data Layer.

Is there any way we can publish the data from MQTT (either from Node-RED or Cedalo MQTT broker) to OPC UA/ ctrlX Data Layer?

Hi ahmadkhairi,

we will release this function also as a ready made app soon, so you, or your customer, don't need to build your own app like described below.

@ahmadKhairi I have been accomplishing this using a custom Python app which registers nodes on the datalayer. You can then write to these via Node-Red and read them over OPC UA in WebIQ.

See: https://github.com/boschrexroth/ctrlx-automation-sdk/tree/main/samples-python/datalayer.provider.all...

hi.. Thanks for the suggestion. Haven't tried running python scripts with the ctrlX Core yet. Maybe will give this a try soon
