Description
0
FLAG_RESTART
BOOL
It indicates that the data has not been updated by the field since the reset of
the device.
1
FLAG_COMM_FAIL
BOOL
Indicates a communication failure in the path between the device where the
data is originated and the report device.
2
FLAG_REMOTE_SUBSTITUTED
BOOL
If TRUE, the data value is replaced in a remote communication device.
3
FLAG_LOCAL_SUBSTITUTED
BOOL
If TRUE, the data value is replaced by the device that generated this flag.
This behavior can happen due to a run in diagnosis or temporary due to
human intervention.
4
FLAG_FILTER
BOOL
Flag used to signal and prevent overload of the events communication
channels, such as oscillations in binary inputs (quick changes).
5
FLAG_OVERFLOW
BOOL
This identifier indicates a quality problem. The attribute value to which the
quality is associated with is beyond the capacity of representation.
6
FLAG_REFERENCE_ERROR
BOOL
This identifier indicates that the value may not be correct because its
reference is out of calibration.
7
FLAG_INCONSISTENT
BOOL
This identifier indicates an inconsistency, detected by an evaluation function.
8
FLAG_OUT_OF_RANGE
BOOL
This identifier indicates a quality error. The attribute value to which the quality
is associated with is beyond the capacity of the capacity of predefined values.
9
FLAG_INACCURATE
BOOL
This identifier indicates that the value does not meet the stated accuracy of
the source.
10
FLAG_OLD_DATA
BOOL
There is an outdated value (if an update does not occur in a specified period
of time).
11
FLAG_FAILURE
BOOL
This identifier indicates an internal or external fault, detected by a supervisory
function.
12
FLAG_OPERATOR_BLOCKED
BOOL
Operator blocked the updating.
13
FLAG_TEST
BOOL
This is an additional identifier used to set a test value, which is not applied for
operational purposes, but simulation.

DNP3 Conversion
Table 4-8 illustrates the quality conversion of DNP3 to internal points. Table 4-9 illustrates the
quality conversion of internal points to DNP3 for Hadron Xtorm Series available for HD8500.
