Tools, such as Smart P&ID, Smart Instrumentation, and SmartPlant Test Tool, that operate in an integrated environment must implement the SmartPlant Adapter interface, among other requirements. Part of the SmartPlant Adapter interface is the SupportsFeature function, by which a tool claims which SmartPlant tool features it supports.
For testing, you can cause SmartPlant Test Tool to claim that it supports one or more of these features. To turn on claims of supported features, click Tools > Options, and click the features for which you want the SmartPlant adapter to respond true.
