Status and trend flags

Common to both types of History Export, the STATUS and STATUS_FLAG columns represent the state of the point at the time the record was recorded where STATUS is the sum of the possible states.

Status flags

State #	State (tag)	State #	State (tag)	State #	State (tag)
0	{ok}	4	{down}	32	{overridden}
1	{disabled}	8	{alarm}	64	{null}
2	{fault}	16	{stale}	128	{unackedAlarm}

For example:

STATUS	STATUS_TAG
15	{disabled, fault, down, alarm}
136	(a;ar,. imacledA;ar,}

Trend flags

The TRENDFLAGS and TRENDFLAGS_TAG columns record event information about the history record, using the same 'sum' method described above.

Trend #	Trend (tag)	Trend #	Trend (tag)	Trend #	Trend (tag)
1	{start}	4	{Hidden}	16	{Interpolated}
2	{OutofOrder}	8	{Modified}
