Diagnostic Structures

The Sentinel V –Diagnostic Structures refers to the dynamic ADCP data associated with fault handling
and diagnostics.

Sentinel V Event Log

Sentinel V Event Log output is included only in systems configured with 47.xx firmware.
A new data type has been added to the PD0 to report events including faults. It is a variable length message
with entries for each active fault. Faults will only be reported if they are active when the ensemble is sent.
