The VisionSystemAssetType is an ObjectType that provides a representation of the machine vision system and organizes the items that constitute it into different folders depending on their function. This type is used to represent the entire machine vision system as an asset. It is formally defined in Table 21.

Note: In order to declare an arbitrary object (i.e., an instance of BaseObjectType or one of its subtypes) as a MachineryComponent which represents a particular component of the machine vision system, said instance shall be referenced by the instance of MachineryComponentsType with a HasComponent reference. It shall also be referenced from the folder representing a collection of the same type of components as it is representing e.g., a BaseObjectType instance (i.e., an instance of any arbitrary object type) representing a computing device, shall be referenced by the instance of MachineryComponentsType with a HasComponent reference, thereby representing a MachineryComponent. It shall also be referenced from the ComputingDevices folder, thereby representing a ComputingDevice.
