Stalled Discovery

Symptom: When performing a discovery, the progress bar should go from 0% to fully discovered gradually
and increase at regular increments (the time this takes depends on how much there is to discover). A stalled
discovery can be identified when the discovery progress decreases to a lower percentage value and the
discovery progress bar stops loading for an extended period of time.
Cause: When this issue occurs, the progress bar value initially increases because a slave device that was
queried does reply. However, the value of the progress bar then goes down because the data request from
the slave device was unsuccessful. The EZ Gateway then continues to try to discover other addresses, but
the progress bar remains stuck at the lower value.
Resolution: Wait for the discovery to complete. There is no timeframe for how long discovery can take
because there are many factors that could prevent a slave device from sending data. Examples of these
factors include: conflicting slave addresses, Secondary Addresses that are close in value to each other,
and multiple devices responding at the same time. The user can check the status of the discovery process
by accessing the FS-GUI page: click the word "Diagnostics" on the bottom of the EZ Gateway M-Bus landing
page, navigate to User Messages, and then click the Driver tab. Scroll to the bottom to see the latest
messages from the gateway.
