MQTT - Store and Forward Capability

Ignition
1

Hi,

I am using Ignition V8.0.10 and have set MQTT communication with a remote Edge device.

How can I test the Store and Forward function in case of communication loss? how can I verify?

Any help will be greatly appreciated

You can disable the Main Gateways MQTT Engine Module. The edge will see that the Primary Host quit listening and will begin storing data as long as your transmission module History is configured.
To test, you should see missing data within tag history configured for this MQTT tags in your main gateway.
Once you reconnect the MQTT Engine Module, the edge sees that the Primary Host is back and forwards all stored data. You should find all missing data filled in.
