When you create a standard descriptor, a number of properties specific to that descriptor become available. The number of properties depend on whether the standard descriptor is connected to an IGSS object. When connected, a number of properties which are linked to the state or value of the IGSS object are available.
To edit the standard descriptor properties, double-click the object or right-click it and select Properties in the pop-up menu, then click the Attributes of <descriptor type> tab.
The properties are presented in a tree structure allowing you to expand or collapse the property groups, as required. Each property group contains a number of properties which can be edited by simply double-clicking the value. When the value is simply Yes or No, double-click it to alternate between the two.
