To create a new historical database point, click Add on the Historical Database Configuration window. The
Historical Tag Configuration window will be displayed with default values (
Figure 5-12 ).

5.2.7 Find Historical Database
The Find button is located in the lower left corner of the Historical Database Configuration window
(
Figure 5-2 ), and can be used to ascertain the presence of a given point in the historical database. If the
point does exist, the Find button quickly locates it on the Historical Tagname list and highlights it. Once
located, the point configuration can be viewed, edited or deleted as desired.
To use this feature, click Find. A window appears. Click the entry box and enter the desired historical data-
base tagname. If only a portion of the tagname is entered, the first entry where the first letters of the tag-
name matches the entered string will be chosen. For example, if the string HR is entered, and the first
tagname to begin with these characters is HRANO1, then this is the tagname that would be highlighted in
the Historical Tagname list.
Click Apply to locate the first instance of the string; the Find window will remain open; click Apply again to
locate the next instance of the string, or enter a new string to be located. Click OK to perform the Find
operation and close the Find window.

The Delete button is used to delete a point or group of adjacent points in the historical database. Click the
tagname of the point to be deleted; it will be highlighted. If more than one point is to be deleted, position the
pointer on the first tagname to be deleted, then press the left mouse button and drag the pointer until all the
points to be deleted are highlighted. Click Delete. A confirmation box will ask:

Click Yes to delete all highlighted points, or click No to exit the operation without deleting anything.
