Tag Quality in Metrics |
Turn this option on if timestamps are needed in each metric data value. By default, this option is off.
Republish Payload After Disconnect
When QoS is 1 or 2 , this setting will force eACM to republish the most recently sent message if it lost the broker connection without confirmation that the message was received
Serialize Publishing
When QoS is 1 or 2 , this setting ensures packages are published in sequence and only after the previous message receipt is confirmed
Include Tag Quality in Metrics
...
If checked, the tag quality of each tag will be published in the metric alongside the value of each tag | |
Include backfill in Birth Message | If checked, all backfill data will be sent in the DBIRTH message instead of the first DDATA message |
Include Node Name in the Node Birth (NBIRTH) message | If checked, an internal string tag will be published in the |

NBIRTH message with the value |
...
Include initial value in Birth Message
...
matching the node name of this install | |
Include Node IP address in the Node Birth (NBIRTH) message | If checked, an internal string tag will be published in the NBIRTH message with the value matching the IP address of this node |
Out of Schedule Publish allowed | When checked, if a majority of tags in a device have a quality change, then an out of schedule publish will take place. This allows the publisher to send DDEATH and DBIRTH messages when it loses and regains connection to an end device. If set to false device messages will be limited to only publish at scheduled times. |
Delay Between Births |
...
The minimum amount of time to wait between rebirth messages, if a rebirth request is issued during the delay the next birth message will not be sent until after the delay | |
Publish Device Death | When enabled, DDEATH messages will be published when an end device loses connection |
