Group Items Group Items are collections of other items that behave as a single item. Group Items are added to a canvas by selecting one or more items and using the Make Group command on the Editor Menu.

Use the Drawing Wizard to quickly draw complex shapes from a symbol library.

Setting up Dynamic Content

The Graphic Editor provides these tools to link graphic items to tags in the SCADA database:

Data Bindings A mechanism to bind the visual appearance of graphic elements to tag value(s).
For example:
  • A text item showing an analog measured value or digital state,
  • A shape where the color indicates the state of a piece of equipment,
  • The position of a fill level indicator,
  • Rotation of turbine blades in a pump.
Operator Actions Areas of the graphic page that respond to operator interaction. For example, an operator might click on an item to:
  • Navigate to another graphic page
  • Open a dialog to enter a new setpoint
  • Open or close a valve
  • Display events associated with a tag
  • View alarms associated with a logical area of the tag database
  • Acknowledge an alarm
Graphic Item Functions Functions to read or write Data Bindings from an Operator Actions. Using these functions you can:
  • Display or hide items on a page, for example a pop-up window.
  • Change the text displayed in a text item.
  • Set the text displayed in the tooltip when the user moves the mouse over an item.
  • Allow or prevent a user from interacting with an item.
Global Bindings You can declare common code and variables in a Global Bindings area. Data Bindings and Operator Actions can reference common code and variables declared in the Global Bindings area.
