Micro-PWC CONFIGURATION GUIDE
232 Historical Database
5.2.3.2 Edit Data Storage Definitions
To change an existing data storage definition, click the desired entry in the list box on the Historical Tag
Configuration window (
Figure 5-2 ), then click Edit below the list box. The Historical Collections Storage
Options window ( Figure 5-11 ) will be displayed. Configuration is performed in the same manner as that for
adding data storage definitions, described in Section 5.2.3.1, Add .
5.2.3.3 Delete Data Storage Definitions
To delete a data storage definition, click the desired entry in the list box on the Historical Tag Configuration
window (
Figure 5-2 ), then click Delete. The entry will be removed from the list box. At least one storage
node must be specified; attempts to remove the last entry from the list box will result in an error message.
5.2.4 Convenience Buttons
In addition to the usual OK and Cancel, five other buttons appear at the bottom of the Historical Tag Con-
figuration window (
Figure 5-2 ). These include Replace, Add, Prev, Next and Default. These buttons pro-
vide a convenient way to configure multiple historical database points without exiting the Historical Tag
Configuration window.
5.2.4.1 Replace
If the configuration of an existing historical database point has been changed, click Replace. The existing
configuration on the system for that historical database point will be replaced by the revised configuration.
5.2.4.2 Add
To create a new historical database point from the Historical Tag Configuration window, using the current
parameter configuration, click Add. The Historical Tag Configuration window is ready to receive new input.
Alternatively, if an existing historical database point has already been configured, select it for Edit, change
the tagname and any other characteristics as desired, then click Add. The new point will be created. This
feature allows creation of a group of historical database points with the same characteristics, without hav-
ing to reconfigure the same parameters for every point, and without leaving the Historical Tag Configura-
tion window.
5.2.4.3 Prev/Next
Use the Prev and Next buttons to move to configuration displays for the historical database points which
are adjacent to the one currently on display. Historical tagnames are listed in alphanumeric order; the
actual order of the points is that shown in the list box of the Historical Database Configuration window
(
Figure 5-1 ).
