Display Pages are the principle
user interface for SCAN1000-Scada and are customised to create a useful user
interface (HMI).
Displays are created by adding Drawing objects to a page and linking them to
dynamic data points to create customised user
displays for the project.
Drawing Objects
There are a wide range of objects available:
- Basic drawing shapes (rectangles, lines, etc)
- Dynamic meters, bar graphs, etc.
- Trend graphs and charts
- User controls (buttons, switches, etc)
There is also the facility to import pictures, drawings, ActiveX objects, etc.
Drawing Editor
Objects are selected from toolbars and menus and positioned on the display
page in a similar manner to other Windows drawing packages. The advantage is that
with this software, drawing objects can be made dynamic to reflect
changes in data, i.e. animated.
The Basic Objects toolbar includes simple objects such as lines, rectangles, text, as well as more
sophisticated dynamic objects such as meters and bar graphs:
Object Properties
Drawing objects have property
pages which can be used to customise and animate each drawing item:
Drawing Tools
A wide range of useful drawing tools are available for Display Page
development. An example is the 'Move' toolbar:
which includes tools to move and order selected objects.
Advanced Facilities
As well as the basic facilities seen so far, Display Pages can include
ActiveX objects, imported vector drawings and displays of complex objects
such as spreadsheets, charts
and trend graph displays.
Library
The project library can hold copies of user defined, complex objects.
These objects
can be designed to be animated when placed on a display page. This allows easy
re-use of designed objects on multiple pages.
Pop-Up Windows
Window objects are used to create pop-up pages, which
float over the normal display page. They can be used for User input, more
detailed information, etc.
