Thread Safety

The properties (Quality, Timestamp, and Value) are guaranteed to be thread safe. Access to these items are protected by a ReaderWriterLock. Multiple threads may simultaneously get the property values; however, only one thread may be accessing the property when setting it's value. These properties are only set from callback methods from the OPC Server.

Remarks

The IOpcValue interface contains the value, quality, and timestamp of a value returned from the OPC Server.
