Symbol Set Objects

The Symbol Set tool allows you to represent changing runtime conditions with changing symbols. By clicking on this tool, then clicking on the graphics page, you can define the symbols which are to display for each condition.

After a symbol set has been added to the page, it can be moved, re-sized, re-shaped, brought to the front etc., and its properties can be edited, just like any other type of object.

To add a Symbol Set:

Click the Symbol tool.
Move the mouse pointer to the desired position on the page, and click with the left mouse button.
When you click the mouse button, the object properties dialog is displayed.
Fill out the relevant properties for the symbol set, and click OK.
Note: There are several radio buttons in Symbol Sets Appearance (described below). When selected, these radio buttons change the appearance of the right hand side of the dialog.

[Type] On / Off

Select this radio button to display one symbol when a particular expression is TRUE, and another when it is FALSE. For example, you could display a red symbol when a particular variable tag is in alarm, and a green symbol when it is not.

See Symbol Set Properties - Appearance General (On/Off).

[Type] Multi-state

This option is useful when you have several possible conditions, occurring together in different combinations, at different times. Select this option to display different symbols for each combination.

For example, three digital variable tags (A,B, and C) can each be ON or OFF at any time. You can display a different symbol for each ON/OFF combination. In other words, you could display a different symbol for each of the following ON/OFF combinations ABC, ABC, ABC, ABC, ABC, ABC, ABC, ABC.

See Symbol Set Properties - Appearance General (Multi-state).

[Type] Array

The Array option allows you to enter an expression which returns an integer. For each unique integer (from 0 to 255), you can display a unique symbol. For example, you could display a different symbol for each threshold of an analog alarm.

See Symbol Set Properties - Appearance General (Array).

[Type] Animated

Select this radio button to display an actual animation (several different symbols in sequence).

When selected, the radio buttons on the dialog box change the appearance of the right hand side of the dialog. These radio buttons are only documented once below.
