Custom Properties

Use custom properties to extend the functionality of a graphic. A custom property can contain:

• A value that can be read and written to.

• An expression that can be read.

• An object equipment.item that can be read and written to if the equipment.item allows being written to.

• A property of an element or graphic.

• A custom property of a graphic.

• A reference to a tag.

For example, for a tank graphic called TankSym you can create a custom property called TankLevel that is calculated from an equipment.item reference to Tank_001.PV. You can then reference the tank level by TankSym.TankLevel.

Custom properties appear in the Properties Editor when no elements are selected. You can edit default initial values of custom properties in the editor directly or use the Edit Custom Properties dialog box to do so.
