OSI PI Collector and Distributor Supported Data Types

The following table maps OSI PI data types to their Historian data type equivalents:


OSI PI Tag Types	Recommended Historian Data Type
`INT32`	`Single Integer, Double Integer`
`FLOAT16, FLOAT32`	`Float`
`FLOAT64`	`Double Float`
`PISTRING`	`Variable String`
`DIGITAL`	`Single Integer` The accompanying digital states are transferred from OSI PI into Historian upon initialization of the collector.

Data Quality Mapping

Data quality mapping from Historian to OSI PI Data Archive is restricted to good/bad. OSI PI's subtypes are not currently mapped by Historian.
