The "Root" node of a GenTL frame grabber may contain features within the following sub-categories:
- Cognex meta-features: Cognex-specific features that are interpreted directly by VisionPro software.
- GenTL System features: Standard GenICam features that control the GenTL System module. These features are prefixed with the three letters "SY_", and are organized under the "SY_Root" category node.
- GenTL Interface features: Standard GenICam features that control the GenTL Interface module. These features are prefixed with the three letters "IF_", and are organized under the "IF_Root" category node.
- GenTL Local Port features: Standard GenICam features that control the GenTL Local Port module. These features are prefixed with the three letters "LP_", and are organized under the "LP_Root" category node.
- GenTL Remote Device features: Standard GenICam features that control the remote device. These features are the features of the camera itself, and are not specified by the GenTL standard. These features are all prefixed with the three letters "RD_", and are organized under the "RD_Root" category node. The "RD_" features are the ones that you will use most of the time. For example, if you want to read the current value of the "BalanceWhiteAuto" feature from your camera, you should read the "RD_BalanceWhiteAuto" feature in VisionPro.
- GenTL Data Stream features: Standard GenICam features that control the GenTL Data Stream module. These features are prefixed with the three letters "DS_", and are organized under the "DS_Root" category node.
