Node-red sparkplug b


We have an issue with the MQTT store and forward process being implemented within Ignition.

I have currently 299 tags on a test project, using Ignition’s Sample_SQLiteDatabase. I am using NodeRed to simulate MQTT Sparkplug B module to test out the Store-and-Forward mechanism. I am getting the data displayed in the Perspective session in Designer when I play it. However, when the comms is halted, we just get “No” data. We were expecting the store and forward feature to store the data once the connection is restored but it’s not working.

Can somebody help me with that.

Kind Regards,

I don’t think the nodered / Javascript sparkplug B libraries does not support the historian flag. At least not native…

You can try to compare packages received from nodered with another ignition mqtt transmission module.

Thank you for that.
