PI Destination

The PI Destination node writes data to an OSI PI Historian Server.

Configuration

Basic

Clear Time Range Before Write

If enabled, the time range of the written values will be cleared, so only the inserted values are existent in the provided time range.

Default: enabled

Insert Options

This option is only available if “Clear Time Range Before Write” is not checked. This options defines the behavior on how the data is inserted.

Available options

Replace
Insert
No Replace
Replace Only
Insert No Compression

Write Partial Data

If this function is activated, the data will be written even if not all configured data of the data group are available.

Connection

PI Connection: Select a PI Configuration configured in the Global Configurations

Signals

Define the signals to write to the PI Historian.

Flow Name: The name of the signal in the incoming data group.
Signal Name (Optional): The name of the signal in the PI Historian. If this field is empty the Signal Name is the same as the Flow Name.

Options

Replace

Add the value to the archive. If any values exist at the same time, will overwrite one of them and set its Substituted flag.

Insert

Add the value to the archive. Any existing values at the same time are not overwritten.

No Replace

Add the value to the archive only if no value exists at the same time. If a value already exists for that time, the passed value is ignored.

Replace Only

Replace an existing value in the archive at the specified time. If no existing value is found, the passed value is ignored.

Insert No Compression

Add the value to the archive without compression. If this value is written to the snapshot, the previous snapshot value will be written to the archive, without regard to compression settings. Note that if a subsequent snapshot value is written without the InsertNoCompression option, the value added with the InsertNoCompression option is still subject to compression.
