8.8 Ethernet and Cellular Push Retries
The DXM can be configured to send register data packets to a webserver. When the Ethernet or cell communications path is
not operating, the DXM retries the send procedure. The communications retry process is outlined below for each
configuration.
Regardless of the communications type (Ethernet or cellular), a failed attempt results in the register data packet being saved
on the local micro SD card
6
. The number of retries will depend upon the network connection type.
When there is bad cellular signal strength or there is no Ethernet connection, the transmission attempts are not counted as
failed attempts to send data. Only when there is a good network connection and there are 10 failed attempts will the
controller archive the data on the SD card. Data archived on the SD card must be manually retrieved.
8.8.1 Ethernet Push Retries
With an Ethernet-based network connection, the DXM retries a message five times. The five retry attempts immediately
follow each other. After all attempts are exhausted, the register data packet is saved on the micro SD card.
At the next scheduled time, the DXM attempts to send the saved packet as well as the newly created register data packet. If
it cannot send the new register data packet, the new register data packet is appended to the saved file on the micro SD card
to be sent later. After 10 rounds of retries, the data set is archived on the micro SD card under folder
_sxi
. No additional
attempts to resend the data are made; the data file must be manually retrieved.
Using SSL on Ethernet will have no retries, but will save each failed attempt to the micro SD card until 10 failed rounds. At
this time, the register data packet is archived.
8.8.2 Cellular Push Retries
In a cellular-connected system there are no retries. Failed transmissions are saved on the micro SD card.
After 10 successive failed attempts, the data is archived in the
_sxi
folder. Send attempts with a low signal quality are not
counted against the 10 count limit. For example, if the cellular antenna is disconnected for period that the DXM controller
would have sent 20 messages under normal circumstances, all 20 messages would be saved and will be retried when the
antenna is reconnected. If the signal quality was good, but the cellular network was not responding, the DXM archives the
register data packets after 10 failed attempts.
8.8.3 Event/Action Rule or Log File Push Retries
Event-based pushes caused by Action rules and locally stored log files sent using email follow the same process when
failures occur, based on the network connection. The failed Event-based messages are resent with the next cyclical schedule
or the next event message that triggers a push message.

Enable HTTP logging to save data on the SD card; this is the factory default. See SETTINGS -> LOGGING in the DXM Configuration Tool.
