Meaning of the buttons placed in the dialog box is following:

Button	Meaning
Export	Saves values displayed in the table into a file. Clicking the button opens the menu allowing you to save values in a text file, CSV file or

to

copy them into the clipboard. It is also possible to save either all the values of the table (the All values item) or only selected values (lines).
Columns	Configuration of columns displayed in the table.
Edit	Edits selected value of the archive object.
Delete	Deletes selected value of the archive object.
Insert	Inserts a new value into the current table position.

Image Removed

Image Added	Shows values of the archive object in the graph.
Close	Closes the dialog box of the archive object.

Note: The buttons Edit, Delete, Insert are disabled if an archive object disallows this activity from HI.

The parameters Row and Column are enabled if the browsed archive object is a structure. When changing row (Row parameter) or column (Column parameter) of the particular archive object and clicking on button Image Removedbutton Image Added, it loads data from the archive. The change is indicated by the red colour color of the parameter Row or Column. You can see the current values in the object name in a title bar.

The button Image Removed button Image Added refreshes the displayed data of the archive object.

If the archive contains more values for a given time interval than may be displayed in the dialog box, you must use the paging functions. For easy orientation and moving within the multi-page list, you can use the buttons located below the list.

Table description

Besides particular values of an archive object, each table line contains other information concerning the given value. Their displaying depend depends on the table column settings. Table The table has the following structure:

Column	Contents
Time	Information about the time when the value was saved into the archive database. If the msec parameter is checked then the column displays time data with the millisecond accuracy.

Checked

The checked Year parameter allows

to display

displaying information about the current year.
Value	Value of the archive object (object Historical value type) in corresponding time. If it contains “???” string, this value is not valid.
Limits	Limit state of the value: InLimit, VL-Limit,L-Limit, H-Limit, VH-Limit, LimitsProblem
Value state	Process state of the value: Invalid, ProcAlarm, NoAckPAlarm, PrAlSilent, Weak, NoAckValue, Transient, Default, Manual, PrAlCrit.
Archive flags	Flags: START, STOP, BLOCK, UNBLOCK, DELETED, USERMODIFY, OLDVAL, PROCESMODIFY, LOADDATA, MONO_TIME, K, L, M.
Value flags	Flags of the value. This column displays only the flags with TRUE value.

Colors in a table:

White color - data from the archive database. An editing Editing is enabled.
Red color - data from the archive database. An editing Editing is disabled.
Grey - life live data from the graphs. An editing Editing is disabled.

The descriptions of of individual value states are explained in the following table.

Value state	Meaning
INLIMIT	The value is at once greater than the low limit (Low Limit) and less than the high limit (High Limit).
VL_LIMIT	The value is less than the lowest limit (Very Low Limit).
L_LIMIT	The value is less than the low limit (Low Limit).
H_LIMIT	The value is less than the high limit (High Limit).
VH_LIMIT	The value is less than the highest limit (Very High Limit).
LIMITSPROBLEM	Condition VLL < LL < HL < VHL is violated.
TRANSIENT	The command to set value was issued at the moment of the value writing into the archive database, but backward reading has not verified the value

setting

yet.
DEFAULT	The value in Default mode (default value).
WEAK	Suspicious value (Weak Value). This value is not valid in the system because all the validity conditions are not met, yet.
INVALID	Invalid object value.
ProcAlarm	The state

is occurred in case that

occurs if the given object has an active process alarm.
NoAckPAlarm	The state

is occurred in case that

occurs if the process alarm is not acknowledged by the operator in

process

the D2000 HI process.
PrAlSilent	The state

is occurred in case that

occurs if the given object hasn't any active process alarm, or the Silent option is enabled

at

in the configuration of object process alarms in the

process

D2000 CNF process.
NoAckValue	The state

is occurred in case that

occurs if the last object value change is not acknowledged by the operator in

process

the D2000 HI process.
Manual	The object value is in a Manual state

,

if it

is

was manually adjusted by the operator in

process

the D2000 HI process.
PrAlCrit	The status

is occurred in case that

occurs if the process alarm is defined as a critical one in the

process

D2000 CNF process.

LOADDATA

Obsolete: value was obtained from OS/2 database SQL Gupta via

On-line

Online archive database import.

Kotva

	af_mono_time
	af_mono_time

MONO_TIME

Value is stored with monotonous time. All values in D2000 version 6.5 and above have this flag. In the case of archive databases, created in previous D2000 versions, this flag is

newer

set for all values newer than the time of starting the new archive.
Note: Flag MONO_TIME is not displayed in HI.

Kotva

	af_k
	af_k

K

Archive flag only occurs in the periodic archives. To avoid unnecessary space consumption in the database, the periodic archives are archived when they change. I.e. if the value and its attributes (limits, value state, value flags) remain the same as in the previous period, it will not be written to the database. During the reading this value will be reconstructed as a copy of the previous value, with changed time and

set

the 'K' archive flag set.

Kotva

	af_l
	af_l

L

The flag is set while reading. A value with such a flag is read from the write cache and is not yet committed in the archive database.

Kotva

	af_m
	af_m

M

The flag is set while reading. A value with such a flag is read from the isochronous cache.
