If there is no connection available to the MQTT broker for the edge gateway, your data is not lost. The edge gateway will then continue logging data and can store it locally for months at a time, depending on how much data you log. This data is locally not accessible. Once the connection has been restored, the logged data will be sent to the MQTT broker.

Requires IXrouter3 firmware 3.12 or higher or SecureEdge / SecureEdge Pro firmware 5.0 or higher (upgrade). Not supported on the IXagent.

Yes. However, note that it's still required for the MQTT broker to support encrypted connections. Unencrypted connections are not supported by Datalogging to MQTT broker.

Create two identical data sources for the same PLC. Check the Use custom broker option only on one of them and make sure that the PLC is capable of accepting two simultaneous connections.

Tags that are logged at the same time will be grouped together in a single data message. It is not possible to enforce a single structure. The data message will contain the data of all tags that are logged at that time. That can be one tag or that can be multiple tags. Make sure that your MQTT broker is able to handle both situations.

You'll need to upload a new, valid, certificate to your MQTT broker settings at Admin > MQTT in the IXON Cloud.

The Edge Gateway will automatically download the latest configuration from the IXON Cloud, which includes your uploaded certificate. So long as the MQTT connection fails, the Edge Gateway will repeat this process every few minutes, but it can also be manually triggered by rebooting the device (either locally or remotely in the IXON Cloud).

While the Edge Gateway has no MQTT connection, the Edge Gateway will continue logging data and can store it locally for months at a time, depending on how much data you log. This data is locally not accessible. Once the MQTT connection has been restored, the logged data will be sent to your MQTT broker.

If a new certificate has been uploaded to your aMQTT broker settings at Admin > MQTT in the IXON Cloud, these will need to be manually applied by rebooting the device (either locally or remotely in the IXON Cloud) or pushing a configuration to the device (if available).
