| PropagateWrite | Determines whether UAServerNode.Write events propagate to the parent node (defaults to True). (Inherited from OpcLabs.EasyOpc.UA.NodeSpace.UAServerNode) |
| ReadAttributeData | The variable data (value, timestamp, status code) seen by OPC reads. |
| SamplingInterval | The current sampling interval, computed as the shortest of the sampling intervals of current data subscriptions. In milliseconds. |
| Site | (Inherited from System.ComponentModel.Component) |
| State | An arbitrary object associated with the node. (Inherited from OpcLabs.BaseLib.NodeSpace.Node) |
| UseDataPolling | Determines whether data polling (internally invoked reads) will be used to handle data subscriptions to this variable. |
| ValueRank | The OPC UA value rank of the variable value. |
| WritableSourceTimestamp | Determines whether the source timestamp of the variable is writable. |
| WritableStatusCode | Determines whether the status code of the variable is writable. |
| WriteAttributeData | The variable data (value, timestamp, status code) modified by OPC writes. |
| WriteLoopback | Determines whether successfully written data will become the read data for subsequent operations. |
