Parameters

value

Type: OSIsoft.AF.AssetAFValue
The value to be written, replaced, or removed in the PI Data Archive.

option

Type: OSIsoft.AF.DataAFUpdateOption
An enumeration value that specifies how to treat duplicate values in the archive. It can also be used to specify that an existing value should be removed.

bufferOption

Type: OSIsoft.AF.DataAFBufferOption
An enumeration value that specifies buffering option.

For successful data write through Buffer, this method requires that PI Buffer Subsystem (PIBufSS) needs to be correctly pre-configured with Buffering Manager. Currently, buffering data through PIBufSS has a limitation where error feedback from PI Data Archive cannot be returned to the caller.

Data write through Buffer will be fanned to Collective members.

Important
Exception reporting is not handled automatically by the AF SDK. Historically, exception reporting has been handled by the application writing data (i.e. Uniint-based interfaces).
