11.3.1.1 Viewing an Historical Database Value
To view the value stored in the Historical Database for any Historical Database point (either a database
point or a Manual Data Entry point) enter the name of the point in the Tagname entry box in the window.
There are two ways to enter a tagname in the entry box:
• Type the name of the Historical Database point in the tagname box, then click the Find button
(to the right of the Time entry box) to display information about the point,
- or -
• click the Find button (to the right of the Tagname entry box) to access another window
containing an alphabetical list of all names of all Historical Database points (see
Figure 11-14 ).
Use the Next and Prev buttons to view the rest of the list. To select a tagname, click on the
name, then click OK. The Historical Tags window will close; the name of the selected point will
be displayed in the Tagname entry box in the Manual Data Entry window, and information
about the point will be displayed.
The following information is displayed about the point whose tagname is entered in the Tagname entry
box: the point’s Historical Database legend (if configured), instrument tagname.atom (or Manual for a Man-
ual Data Entry point), the collection rate, and the collection option (or data type for a Manual Data Entry
point).
The time-stamp of the sample in the database that was the newest at the instant that the value is dis-
played, and the value stored for that time will also be displayed. (The Historical Database for database
points will continue to be updated, so newer data can be viewed after it has been collected using the Next
button, described below.)
To view the value with the same time-stamp for the next point in the alphabetical list of Historical Database
points click Next. If the database does not contain a value for the next point with that same time-stamp, the
time-stamp will be displayed, but without a value. A value can be inserted as described below.
To move back through the alphabetical list one tagname at a time, click the Prev button to the right of the
tagname Find button.
To view the value for a different time for the point already in the tagname entry box:
• Click the time entry box and enter the time-stamp of the value you want to view; then click on
the Time Find button to display the value for that time-stamp.
