7 Creating Web Pages with
TAC XBuilder
7.1 Mapping MicroNet Point Signals to Web Pages
Within XBuilder, each imported MicroNet point has an associated sig-
nal, termed a “point signal”, which represents the current value of the
point. For a description of MicroNet points, refer to Chapter 9, “Micro-
Net Objects in XBuilder”, on page 63. You can use MicroNet point sig-
nals within web pages in your project.
Mapping a MicroNet point to a web page can be as easy as dragging a
signal from XBuilder’s network view and dropping it onto the appropri-
ate web page in the system view. The way the point information on a
page is displayed to the user, and the way it can be used, depends on the
type of web page on which it resides.The procedures for mapping point
signals are described below.
7.1.1 Using Signals Folders
If the value of a point signal is to be used in several places, it is a good
idea to create a signal object in a Signals folder and link to it using short-
cuts.
To create and use a signals folder
1
In the system view, select and right-click a folder, point to New
and click Folder .
2
Rename the folder to “Signals”.
3
Drag the signals as required from the MicroNet network to the
Signals folder.
4
Drag any of these signals to a values page, graphics page and so
on, to create the required shortcuts.
7.1.2 Mapping MicroNet Point Signals to Values Pages
In the following example, we will map MicroNet point information to a
values page.
Tip
It is strongly recommended that Signals folders are created along with
a point signal for each MicroNet point, and that each signal is dragged
from the Signals folder to wherever it is needed. In this way, if a spe-
cific signal needs to be changed, it need only be changed once (in the
Signals folder).
