HART Pass-through “Reason Code” definitions
The HART Pass-through
Reason Code
is a value that is reported when a Pass-
through reply message returns the general
Status
value as DR_DEAD(35). It
provides you with a diagnostic code to look up more detail on why the pass-
through message failed. This code is returned in Offset 3 of the reply message for
Pass-through Init or Query messages whenever the
Status
value at Offset 0 is set
to DR_DEAD(35).
