The Historian Data Importer utility can only be used with files in what formats?

The Historian Data Importer utility is specifically designed to integrate data into the AVEVA Historian Server, and its compatibility is limited to certain file formats that are optimized for this purpose. Fast Load format and InTouch History files are recognized as the appropriate types because they are structured in a way that aligns with the internals of the Historian, enabling efficient data ingestion and preserving data integrity during the import process.

Fast Load format is particularly designed for high-performance scenarios where bulk data transfer is essential, allowing for efficient loading of large datasets. InTouch History files, on the other hand, are used to store historical process data generated by the AVEVA InTouch HMI, reflecting a direct connection to AVEVA's ecosystem, making them ideal for historical data analytics in conjunction with the Historian Server.

While the other choices, such as binary, XML, CSV, Excel, JSON, and YAML formats, may be common file types for data storage and generation in various applications, they do not possess the structural compatibility or optimized features that the Historian Data Importer requires for effective data management and retrieval in the context of AVEVA applications.
