Name | Description | |
---|---|---|
![]() | DefaultAccessPath | Default access path. An empty string. |
![]() | DefaultRequestedDataType | Default requested data type. Equals to OpcLabs.BaseLib.ComInterop.VarTypes.Empty. |
Name | Description | |
---|---|---|
![]() | AccessPath | Specifies the access path for the OPC item. The default is "" (an empty string). |
![]() | AliasName | When non-empty, specifies the name of the alias that will be used in place of this object. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | ArgumentString | The node descriptor in form of an argument string, i.e. a key=value pairs separated by semicolons. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | BrowsePath | Specifies the browse path for the OPC node. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | BrowsePathStartingNodeDescriptor | The starting node descriptor of the browse path. (Inherited from OpcLabs.EasyOpc.DataAccess.DANodeDescriptor) |
![]() | HasBrowsePath | Determines whether there is a non-null browse path in the descriptor. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |

![]() | IsAliased | Determines whether this object is aliased. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | IsNull | Determines whether the node descriptor is null, i.e. specifies neither node ID nor a browse path. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | IsRoot | Determines whether this object describes a root of the address space. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | ItemId | Contains OPC item identifier (empty string for the root, null reference if unknown). (Inherited from OpcLabs.EasyOpc.DataAccess.DANodeDescriptor) |
![]() | NodeId | Contains node identifier (empty string for the root, null reference if unknown). (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() | NodePath | Contains node path (empty string for the root, null reference if unknown). Only used with OPC XML. (Inherited from OpcLabs.EasyOpc.NodeDescriptor) |
![]() ![]() | Null | A null item descriptor (contains a null node ID and a null browse path). |
![]() | RequestedDataType | Specifies the data type requested. Setting this property to OpcLabs.BaseLib.ComInterop.VarTypes.Empty means that the server's canonical data type should be used. |
