Table 142 - Buffer Event Types
Worked Example of Event Decoding
Each event log entry is a 16 byte record consisting of a number of sub
structures: Example hex data on the wire: 01 15 71F53854 9600 00 00 00 00
00 40 00 00

Status

Notes
While the returned data is the same, the trigger is different in each case.
A change in the upper 16 bits (considered 'pre-alarm' data) triggers a measurement alarm status event.
A change in the overall alarm state (true or false) triggers a voted alarm status change.
The voted alarm status changes are categorized as OK, Alert, or Danger, which is based on which alarm
output they relate to (encoded as bits 14/15).
The special relay source alarm status is used where a dedicated module fail or 'inhibit active' relay has
been configured and reflects a change in status of this monitoring.

Notes
Buffer events indicate a change in status of these buffers (example: armed to populating or population to
data ready)
