Node Status Byte Definition Table

NODE
STATUS
STATUS DESCRIPTION
0
CONTROLLER
INACTIVE
The controller at this node has not responded to a
poll for at least 40 seconds.
If a controller does eventually respond at this
Node ID, its status will be changed to “0x04 -
CONTROLLER HEALTHY.”
1
CONTROLLER
STOPPED
RESPONDING
The controller at this node has not responded to a
poll in over 10 seconds.
If the controller does not respond to a poll within
another 30 seconds, its status will be changed to
“0x00 - CONTROLLER INACTIVE.”
If the controller does eventually respond to a poll,
its status will be changed back to “0x04 -
CONTROLLER HEALTHY”
2
CONTROLLER
HAS PROBLEM
The controller at this node has missed at least 3
consecutive polls.
If the controller does not respond to a poll within
another 10 seconds, its status will be changed to
“0x01 - CONTROLLER STOPPED
RESPONDING.”
If the controller does eventually respond to a poll,
its status will be changed back to “0x04 -
CONTROLLER HEALTHY.”
3
CONTROLLER
EXPECTED
SOON
This Node Status indicates that a controller is
temporarily disconnected or that it is being moved
to another Node ID.
Because a controller is “expected” to appear
soon, the Gateway will poll this node more
frequently than other ‘inactive’ nodes.
4
CONTROLLER
HEALTHY
The controller at this node is healthy and
responding to polls.
However, if the controller misses 3 consecutive
polls, its status will be changed to “0x02 -
CONTROLLER HAS PROBLEM.”
5
CONTROLLER
DOWNLOADING
This status is only applied to a controller that is
currently downloading and installing new firmware
to its flash memory.
To optimize polling and allow for the fastest
possible firmware installation, the Gateway will
temporarily halt the polling of this node until the
controller has finished its installation.
