Exceptions
ExceptionDescription

One of the arguments provided to a method is not valid.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

When writing, be aware that writing the server timestamp is not supported by some servers, including the OPC Foundation sample server.

In OPC UA PubSub, the server timestamp is only filled in when it is contained in the dataset message. In UADP, this means only when an actual DataValue has been received, which can be either when the DataValue encoding is used, or when DataValue is contained within a Variant.

If you are using VBA in Excel, beware that it reduces the precision of date/times from OLE Automation to seconds. In order to achieve milliseconds precision from VBA in Excel, use the OpcLabs.EasyOpc.UA.UADataValue.ServerTimestampDouble property instead.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.
