The ConnectedTo ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of IsPhysicallyConnectedTo ReferenceType.

The semantic of this ReferenceType is to link together Assets. This Reference indicates that the Asset the Reference points to is a part connected to the Asset, which is the starting point of the Reference by means of an electrical cable. Typically, the Assets are at different physical locations, even if the physical location is not a great distance. An example for this Reference is a sensor connected by a cable to an interface module or an electric motor connected to a drive inverter. Another example might be a monitor is ConnectedTo the PC, or the PC is ConnectedTo the Monitor.

The SourceNode of this ReferenceType shall be an instance of AssetConnectorType (or subtypes) or an Asset.

The TargetNode of this ReferenceType shall be an instance of AssetConnectorType (or subtypes) or an Asset.

The ConnectedTo ReferenceType is formally defined in Table 208.
