• Create a sketch of how the graphic looks. Include in this sketch a list of
database points and corresponding variables that will be represented in the
graphic. Note which points have defined alarms and note the data point
types.
• Create any new symbols (if not available in the Symbol index) that will be
used in the new graphic by selecting New Symbol.
• Save and then generate the new symbol. The generated symbol appears in
the Symbol index. The symbol can then be added to the graphic.
• Create the new graphic by adding labels, values, bar graphs (for a data point)
or/and symbols (for example, valve). Place Conditions on any selected
object, if needed. Expand the contents of the graphic by placing one or more
buttons that access other screens like other graphics or a Tank Detail
window.
• Adding geometric shapes such as lines and rectangles can also enhance the
graphic.
• Save and then generate the new graphic. Generating the graphic places the
graphic in the Graphic Index. Once placed in the Graphic Index, the graphic
becomes available for display in the Operate program.
• In Operate, open the graphic under Operate’s Display menu. All real-time
values are then displayed in the graphic. An example graphic in Operate is
seen on the previous page.
How a graphic is used in the Operate application
The previous example shows what a Site Overview graphic looks like. This
graphic is a representation of a group of tanks. All of the contents were created
using lines, rectangles, bitmaps, bar graphs, values, and labels.
In this example, each tank name has an associated button (append) which, when
clicked on, displays a Tank Detail window. Tank levels are indicated by dynamic
bar graphs representing the associated data point variables. Each valve indicates
current status with standard color codes.
Command buttons may be added to each tank or valve that would open a
standard FuelsManager Operator Command dialog box. Operator Commands are
defined for selected points in database edit. If defined, a dialog box is displayed
allowing the operator to enter a value or issue a command. In this example, the
operator can issue valve open/close commands. The pipeline objects are
animated such that they change color to indicate flow within the particular
segment.
Draw window
This section describes the basic Draw window and components. This window
consists of a drawing space, menu bar, and a toolbar.
Note! Only one graphic or symbol
may be opened at a time.
The Drawing space
The drawing space is the area where drawn objects are created and displayed.
When you start Draw, the drawing space is empty. You have the option to use a
grid to position objects or to draw with precision.
The Draw toolbar
A toolbar is displayed at the bottom of the window. The toolbar has been provided
for easy access to the drawing tools. It also displays the current pen/brush color
