The SlotType represents a physical slot to which a module can be attached, e.g., in a modular Asset like a PLC backplane or modular IO device.
The SlotType is formally defined in Table 37.

Id is from AssetConnectorType and is mandatory in SlotType. It shall start at 1 and increment by 1 for each physical slot in a rack or device.
The optional LogicalId represents the “logical slot number” that might be assigned to a physical ID. For example, module 3 is physically plugged into slot 3, but internally it is used as slot 8.
Each Slot that has a module plugged into it shall have a HasPhysicalComponent Reference (see OPC 10000-23) or a subtype of it, or an IsPhysicallyConnectedTo Reference or a subtype of it, indicating the Asset that occupies the Slot.
